Features#


A date picker can be built using <input type="date">, but this is very limited in functionality, lacking in internationalization capabilities, inconsistent between browsers, and difficult to style. DatePicker helps achieve accessible and international date and time pickers that can be styled as needed.

  • Dates and times – Support for dates and times with configurable granularity.
  • International – Support for 13 calendar systems used around the world, including Gregorian, Buddhist, Islamic, Persian, and more. Locale-specific formatting, number systems, hour cycles, and right-to-left support are available as well.
  • Time zone aware – Dates and times can optionally include a time zone. All modifications follow time zone rules such as daylight saving time.
  • Accessible – Each date and time unit is displayed as an individually focusable and editable segment, which allows users an easy way to edit dates using the keyboard, in any date format and locale. Users can also open a calendar popover to select dates in a standard month grid. Localized screen reader messages are included to announce when the selection and visible date range change.
  • Touch friendly – Date segments are editable using an easy to use numeric keypad, and all interactions are accessible using touch-based screen readers.
  • Customizable – As with all of React Aria, the DOM structure and styling of all elements can be fully customized.

Read our blog post for more details about the internationalization, accessibility, and user experience features implemented by DatePicker.

Anatomy#


Event date9 / 17 / 2021GroupLabelButtonFieldSeptember 2021SMTWTF5789101314151619202122232412326272930628S11182541217CalendarDialog

A date picker consists of a label, and group containing a date field and a button. Clicking the button opens a popup containing a calendar. The date field includes segments representing each unit of a date and time (e.g. years, months, days, etc.), each of which is individually focusable and editable using the keyboard. The calendar popup offers a more visual way of choosing a date.

DatePicker also supports optional description and error message elements, which can be used to provide more context about the field, and any validation messages. These are linked with the input via the aria-describedby attribute.

If the date picker does not have a visible label, an aria-label or aria-labelledby prop must be passed instead to identify it to assistive technology.

Note that most of this anatomy is shared with DateRangePicker, so you can reuse many components between them if you have both.

Concepts#

DatePicker makes use of the following concepts:

Composed components#

A DatePicker uses the following components, which may also be used standalone or reused in other components.

Label
A label provides context for an input element.
DateField
A date field allows a user to enter and edit date values using a keyboard.
Button
A button allows a user to perform an action.
Popover
A popover displays content in context with a trigger element.
Dialog
A dialog is an overlay shown above other content in an application.
Calendar
A calendar allows a user to select a single date from a date grid.

styleCSSProperties( (values: CalendarCellRenderProps )) => CSSPropertiesThe inline style for the element. A function may be provided to compute the style based on component state.

Styling#


React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin className attribute which can be targeted using CSS selectors. These follow the react-aria-ComponentName naming convention.

.react-aria-DatePicker {
  /* ... */
}
.react-aria-DatePicker {
  /* ... */
}
.react-aria-DatePicker {
  /* ... */
}

A custom className can also be specified on any component. This overrides the default className provided by React Aria with your own.

<DateInput className="my-date-input">
  {/* ... */}
</DateInput>
<DateInput className="my-date-input">
  {/* ... */}
</DateInput>
<DateInput className="my-date-input">
  {/* ... */}
</DateInput>

In addition, some components support multiple UI states (e.g. focused, placeholder, readonly, etc.). React Aria components expose states using DOM attributes, which you can target in CSS selectors. These are ARIA attributes wherever possible, or data attributes when a relevant ARIA attribute does not exist. For example:

.react-aria-DateSegment[data-placeholder] {
  /* ... */
}

.react-aria-DateSegment[aria-readonly] {
  /* ... */
}
.react-aria-DateSegment[data-placeholder] {
  /* ... */
}

.react-aria-DateSegment[aria-readonly] {
  /* ... */
}
.react-aria-DateSegment[data-placeholder] {
  /* ... */
}

.react-aria-DateSegment[aria-readonly] {
  /* ... */
}

The className and style props also accept functions which receive states for styling. This lets you dynamically determine the classes or styles to apply, which is useful when using utility CSS libraries like Tailwind.

<DateSegment
  className={({ isPlaceholder }) =>
    isPlaceholder ? 'bg-gray-300' : 'bg-gray-600'}
/>
<DateSegment
  className={({ isPlaceholder }) =>
    isPlaceholder ? 'bg-gray-300' : 'bg-gray-600'}
/>
<DateSegment
  className={(
    { isPlaceholder }
  ) =>
    isPlaceholder
      ? 'bg-gray-300'
      : 'bg-gray-600'}
/>

Render props may also be used as children to alter what elements are rendered based on the current state. For example, you could render the placeholder as a separate element to always reserve space for it.

<DateSegment>
  {({ text, placeholder, isPlaceholder }) => (
    <>
      <span style={{ visibility: isPlaceholder ? 'visible' : 'hidden' }}>
        {placeholder}
      </span>
      {isPlaceholder ? '' : text}
    </>
  )}
</DateSegment>
<DateSegment>
  {({ text, placeholder, isPlaceholder }) => (
    <>
      <span
        style={{
          visibility: isPlaceholder ? 'visible' : 'hidden'
        }}
      >
        {placeholder}
      </span>
      {isPlaceholder ? '' : text}
    </>
  )}
</DateSegment>
<DateSegment>
  {(
    {
      text,
      placeholder,
      isPlaceholder
    }
  ) => (
    <>
      <span
        style={{
          visibility:
            isPlaceholder
              ? 'visible'
              : 'hidden'
        }}
      >
        {placeholder}
      </span>
      {isPlaceholder
        ? ''
        : text}
    </>
  )}
</DateSegment>

isHovered[data-hovered]Whether the button is currently hovered with a mouse.
isPressed[data-pressed]Whether the button is currently in a pressed state.
isFocused:focusWhether the button is focused, either via a mouse or keyboard.
isFocusVisible[data-focus-visible]Whether the button is keyboard focused.
isDisabled:disabledWhether the button is disabled.

Popover#

The Popover component can be targeted with the .react-aria-Popover CSS selector, or by overriding with a custom className. Note that it renders in a React Portal, so it will not appear as a descendant of the DatePicker in the DOM. It supports the following states and render props:

NameCSS SelectorDescription
placement[data-placement="left | right | top | bottom"]The placement of the tooltip relative to the trigger.
isEntering[data-entering]Whether the popover is currently entering. Use this to apply animations.
isExiting[data-exiting]Whether the popover is currently exiting. Use this to apply animations.

Dialog#

A Dialog can be targeted with the .react-aria-Dialog CSS selector, or by overriding with a custom className.

Calendar#

A Calendar can be targeted with the .react-aria-Calendar CSS selector, or by overriding with a custom className.

CalendarGrid#

A CalendarGrid can be targeted with the .react-aria-CalendarGrid CSS selector, or by overriding with a custom className. When a function is provided as children, a default <CalendarGridHeader> and <CalendarGridBody> are rendered. If you need to customize the styling of the header cells, you can render them yourself. See the Calendar docs for an example.

CalendarGridHeader#

A CalendarGridHeader can be targeted with the .react-aria-CalendarGridHeader CSS selector, or by overriding with a custom className.

CalendarHeaderCell#

A CalendarHeaderCell can be targeted with the .react-aria-CalendarHeaderCell CSS selector, or by overriding with a custom className.

CalendarGridBody#

A CalendarGridBody can be targeted with the .react-aria-CalendarGridBody CSS selector, or by overriding with a custom className.

CalendarCell#

A CalendarCell can be targeted with the .react-aria-CalendarCell CSS selector, or by overriding with a custom className. It supports the following states:

NameCSS SelectorDescription
dateThe date that the cell represents.
formattedDateThe day number formatted according to the current locale.
isHovered[data-hovered]Whether the cell is currently hovered with a mouse.
isPressed[data-pressed]Whether the cell is currently being pressed.
isSelected[data-selected]Whether the cell is selected.
isSelectionStart[data-selection-start]Whether the cell is the first date in a range selection.
isSelectionEnd[data-selection-end]Whether the cell is the last date in a range selection.
isFocused:focusWhether the cell is focused.
isFocusVisible[data-focus-visible]Whether the cell is keyboard focused.
isDisabled[data-disabled]

Whether the cell is disabled, according to the calendar's minValue, maxValue, and isDisabled props. Disabled dates are not focusable, and cannot be selected by the user. They are typically displayed with a dimmed appearance.

isOutsideVisibleRange[data-outside-visible-range]

Whether the cell is outside the visible range of the calendar. For example, dates before the first day of a month in the same week.

isOutsideMonth[data-outside-month]Whether the cell is outside the current month.
isUnavailable[data-unavailable]

Whether the cell is unavailable, according to the calendar's isDateUnavailable prop. Unavailable dates remain focusable, but cannot be selected by the user. They should be displayed with a visual affordance to indicate they are unavailable, such as a different color or a strikethrough.

Note that because they are focusable, unavailable dates must meet a 4.5:1 color contrast ratio, as defined by WCAG.

isInvalid[aria-invalid]Whether the cell is part of an invalid selection.

Text#

The help text elements within a DatePicker can be targeted with the [slot=description] and [slot=errorMessage] CSS selectors, or by adding a custom className.

Reusable wrappers#


If you will use a DatePicker in multiple places in your app, you can wrap all of the pieces into a reusable component. This way, the DOM structure, styling code, and other logic are defined in a single place and reused everywhere to ensure consistency.

This example wraps DatePicker and all of its children together into a single component which accepts a label prop, which is passed to the right place. It also shows how to use the description and errorMessage slots to render help text (see below for details).

import type {DatePickerProps, DateValue} from 'react-aria-components';
import {Text} from 'react-aria-components';

interface MyDatePickerProps<T extends DateValue> extends DatePickerProps<T> {
  label?: string;
  description?: string;
  errorMessage?: string;
}

function MyDatePicker<T extends DateValue>(
  { label, description, errorMessage, ...props }: MyDatePickerProps<T>
) {
  return (
    <DatePicker {...props}>

      <Group>

Usage#


The following examples show how to use the MyDatePicker component created in the above example.

Value#

A DatePicker displays a placeholder by default. An initial, uncontrolled value can be provided to the DatePicker using the defaultValue prop. Alternatively, a controlled value can be provided using the value prop.

Date values are provided using objects in the @internationalized/date package. This library handles correct international date manipulation across calendars, time zones, and other localization concerns. DatePicker supports values of the following types:

  • CalendarDate – a date without any time components. May be parsed from a string representation using the parseDate function. Use this type to represent dates where the time is not important, such as a birthday or an all day calendar event.
  • CalendarDateTime – a date with a time, but not in any specific time zone. May be parsed from a string representation using the parseDateTime function. Use this type to represent times that occur at the same local time regardless of the time zone, such as the time of New Years Eve fireworks which always occur at midnight. Most times are better stored as a ZonedDateTime.
  • ZonedDateTime – a date with a time in a specific time zone. May be parsed from a string representation using the parseZonedDateTime, parseAbsolute, or parseAbsoluteToLocal functions. Use this type to represent an exact moment in time at a particular location on Earth.
import {parseDate} from '@internationalized/date';

function Example() {
  let [value, setValue] = React.useState(parseDate('2020-02-03'));

  return (
    <>
      <MyDatePicker
        label="Date (uncontrolled)"
        defaultValue={parseDate('2020-02-03')} />
      <MyDatePicker
        label="Date (controlled)"
        value={value}
        onChange={setValue} />
    </>
  );
}
import {parseDate} from '@internationalized/date';

function Example() {
  let [value, setValue] = React.useState(
    parseDate('2020-02-03')
  );

  return (
    <>
      <MyDatePicker
        label="Date (uncontrolled)"
        defaultValue={parseDate('2020-02-03')}
      />
      <MyDatePicker
        label="Date (controlled)"
        value={value}
        onChange={setValue}
      />
    </>
  );
}
import {parseDate} from '@internationalized/date';

function Example() {
  let [value, setValue] =
    React.useState(
      parseDate(
        '2020-02-03'
      )
    );

  return (
    <>
      <MyDatePicker
        label="Date (uncontrolled)"
        defaultValue={parseDate(
          '2020-02-03'
        )}
      />
      <MyDatePicker
        label="Date (controlled)"
        value={value}
        onChange={setValue}
      />
    </>
  );
}

Events#

DatePicker accepts an onChange prop which is triggered whenever the date is edited by the user. The example below uses onChange to update a separate element with a formatted version of the date in the user's locale and local time zone. This is done by converting the date to a native JavaScript Date object to pass to the formatter.

import {getLocalTimeZone} from '@internationalized/date';
import {useDateFormatter} from '@react-aria/i18n';

function Example() {
  let [date, setDate] = React.useState(parseDate('1985-07-03'));
  let formatter = useDateFormatter({dateStyle: 'full'});

  return (
    <>
      <MyDatePicker label="Birth date" value={date} onChange={setDate} />
      <p>Selected date: {formatter.format(date.toDate(getLocalTimeZone()))}</p>
    </>
  );
}
import {getLocalTimeZone} from '@internationalized/date';
import {useDateFormatter} from '@react-aria/i18n';

function Example() {
  let [date, setDate] = React.useState(
    parseDate('1985-07-03')
  );
  let formatter = useDateFormatter({ dateStyle: 'full' });

  return (
    <>
      <MyDatePicker
        label="Birth date"
        value={date}
        onChange={setDate}
      />
      <p>
        Selected date:{' '}
        {formatter.format(date.toDate(getLocalTimeZone()))}
      </p>
    </>
  );
}
import {getLocalTimeZone} from '@internationalized/date';
import {useDateFormatter} from '@react-aria/i18n';

function Example() {
  let [date, setDate] =
    React.useState(
      parseDate(
        '1985-07-03'
      )
    );
  let formatter =
    useDateFormatter({
      dateStyle: 'full'
    });

  return (
    <>
      <MyDatePicker
        label="Birth date"
        value={date}
        onChange={setDate}
      />
      <p>
        Selected date:
        {' '}
        {formatter
          .format(
            date.toDate(
              getLocalTimeZone()
            )
          )}
      </p>
    </>
  );
}

Time zones#

DatePicker is time zone aware when a ZonedDateTime object is provided as the value. In this case, the time zone abbreviation is displayed, and time zone concerns such as daylight saving time are taken into account when the value is manipulated.

In most cases, your data will come from and be sent to a server as an ISO 8601 formatted string. @internationalized/date includes functions for parsing strings in multiple formats into ZonedDateTime objects. Which format you use will depend on what information you need to store.

  • parseZonedDateTime – This function parses a date with an explicit time zone and optional UTC offset attached (e.g. "2021-11-07T00:45[America/Los_Angeles]" or "2021-11-07T00:45-07:00[America/Los_Angeles]"). This format preserves the maximum amount of information. If the exact local time and time zone that a user selected is important, use this format. Storing the time zone and offset that was selected rather than converting to UTC ensures that the local time is correct regardless of daylight saving rule changes (e.g. if a locale abolishes DST). Examples where this applies include calendar events, reminders, and other times that occur in a particular location.
  • parseAbsolute – This function parses an absolute date and time that occurs at the same instant at all locations on Earth. It can be represented in UTC (e.g. "2021-11-07T07:45:00Z"), or stored with a particular offset (e.g. "2021-11-07T07:45:00-07:00"). A time zone identifier, e.g. America/Los_Angeles, must be passed, and the result will be converted into that time zone. Absolute times are the best way to represent events that occurred in the past, or future events where an exact time is needed, regardless of time zone.
  • parseAbsoluteToLocal – This function parses an absolute date and time into the current user's local time zone. It is a shortcut for parseAbsolute, and accepts the same formats.
import {parseZonedDateTime} from '@internationalized/date';

<MyDatePicker
  label="Event date"
  defaultValue={parseZonedDateTime('2022-11-07T00:45[America/Los_Angeles]')}
/>
import {parseZonedDateTime} from '@internationalized/date';

<MyDatePicker
  label="Event date"
  defaultValue={parseZonedDateTime(
    '2022-11-07T00:45[America/Los_Angeles]'
  )}
/>
import {parseZonedDateTime} from '@internationalized/date';

<MyDatePicker
  label="Event date"
  defaultValue={parseZonedDateTime(
    '2022-11-07T00:45[America/Los_Angeles]'
  )}
/>

DatePicker displays times in the time zone included in the ZonedDateTime object. The above example is always displayed in Pacific Standard Time because the America/Los_Angeles time zone identifier is provided. @internationalized/date includes functions for converting dates between time zones, or parsing a date directly into a specific time zone or the user's local time zone, as shown below.

import {parseAbsoluteToLocal} from '@internationalized/date';

<MyDatePicker
  label="Event date"
  defaultValue={parseAbsoluteToLocal('2021-11-07T07:45:00Z')}
/>
import {parseAbsoluteToLocal} from '@internationalized/date';

<MyDatePicker
  label="Event date"
  defaultValue={parseAbsoluteToLocal(
    '2021-11-07T07:45:00Z'
  )}
/>
import {parseAbsoluteToLocal} from '@internationalized/date';

<MyDatePicker
  label="Event date"
  defaultValue={parseAbsoluteToLocal(
    '2021-11-07T07:45:00Z'
  )}
/>

Granularity#

The granularity prop allows you to control the smallest unit that is displayed by DatePicker. By default, CalendarDate values are displayed with "day" granularity (year, month, and day), and CalendarDateTime and ZonedDateTime values are displayed with "minute" granularity. More granular time values can be displayed by setting the granularity prop to "second".

In addition, when a value with a time is provided but you wish to only display the date, you can set the granularity to "day". This has no effect on the actual value (it still has a time component), only on what fields are displayed. In the following example, two DatePickers are synchronized with the same value, but display different granularities.

function Example() {
  let [date, setDate] = React.useState(
    parseAbsoluteToLocal('2021-04-07T18:45:22Z')
  );

  return (
    <>
      <MyDatePicker
        label="Date and time"
        granularity="second"
        value={date}
        onChange={setDate}
      />
      <MyDatePicker
        label="Date"
        granularity="day"
        value={date}
        onChange={setDate}
      />
    </>
  );
}
function Example() {
  let [date, setDate] = React.useState(
    parseAbsoluteToLocal('2021-04-07T18:45:22Z')
  );

  return (
    <>
      <MyDatePicker
        label="Date and time"
        granularity="second"
        value={date}
        onChange={setDate}
      />
      <MyDatePicker
        label="Date"
        granularity="day"
        value={date}
        onChange={setDate}
      />
    </>
  );
}
function Example() {
  let [date, setDate] =
    React.useState(
      parseAbsoluteToLocal(
        '2021-04-07T18:45:22Z'
      )
    );

  return (
    <>
      <MyDatePicker
        label="Date and time"
        granularity="second"
        value={date}
        onChange={setDate}
      />
      <MyDatePicker
        label="Date"
        granularity="day"
        value={date}
        onChange={setDate}
      />
    </>
  );
}

If no value or defaultValue prop is passed, then the granularity prop also affects which type of value is emitted from the onChange event. Note that by default, time values will not have a time zone because none was supplied. You can override this by setting the placeholderValue prop explicitly. Values emitted from onChange will use the time zone of the placeholder value.

import {now} from '@internationalized/date';

<MyDatePicker
  label="Event date"
  granularity="second" />
<MyDatePicker
  label="Event date"
  placeholderValue={now('America/New_York')}
  granularity="second" />
import {now} from '@internationalized/date';

<MyDatePicker
  label="Event date"
  granularity="second" />
<MyDatePicker
  label="Event date"
  placeholderValue={now('America/New_York')}
  granularity="second" />
import {now} from '@internationalized/date';

<MyDatePicker
  label="Event date"
  granularity="second"
/>
<MyDatePicker
  label="Event date"
  placeholderValue={now(
    'America/New_York'
  )}
  granularity="second"
/>

International calendars#

DatePicker supports selecting dates in many calendar systems used around the world, including Gregorian, Hebrew, Indian, Islamic, Buddhist, and more. Dates are automatically displayed in the appropriate calendar system for the user's locale. The calendar system can be overridden using the Unicode calendar locale extension, passed to the I18nProvider component.

Selected dates passed to onChange always use the same calendar system as the value or defaultValue prop. If no value or defaultValue is provided, then dates passed to onChange are always in the Gregorian calendar since this is the most commonly used. This means that even though the user selects dates in their local calendar system, applications are able to deal with dates from all users consistently.

The below example displays a DatePicker in the Hindi language, using the Indian calendar. Dates emitted from onChange are in the Gregorian calendar.

import {I18nProvider} from '@react-aria/i18n';

function Example() {
  let [date, setDate] = React.useState<DateValue | null>(null);
  return (
    <I18nProvider locale="hi-IN-u-ca-indian">
      <MyDatePicker label="Date" value={date} onChange={setDate} />
      <p>Selected date: {date?.toString()}</p>
    </I18nProvider>
  );
}
import {I18nProvider} from '@react-aria/i18n';

function Example() {
  let [date, setDate] = React.useState<DateValue | null>(
    null
  );
  return (
    <I18nProvider locale="hi-IN-u-ca-indian">
      <MyDatePicker
        label="Date"
        value={date}
        onChange={setDate}
      />
      <p>Selected date: {date?.toString()}</p>
    </I18nProvider>
  );
}
import {I18nProvider} from '@react-aria/i18n';

function Example() {
  let [date, setDate] =
    React.useState<
      DateValue | null
    >(null);
  return (
    <I18nProvider locale="hi-IN-u-ca-indian">
      <MyDatePicker
        label="Date"
        value={date}
        onChange={setDate}
      />
      <p>
        Selected date:
        {' '}
        {date
          ?.toString()}
      </p>
    </I18nProvider>
  );
}

Minimum and maximum values#

The minValue and maxValue props can also be used to perform builtin validation. This prevents the user from selecting dates outside the valid range in the calendar, and marks the date field as invalid using ARIA. You should implement a visual indication that the date picker is invalid as well.

This example only accepts dates after today.

import {today} from '@internationalized/date';

<MyDatePicker
  label="Appointment date"
  minValue={today(getLocalTimeZone())}
  defaultValue={parseDate('2022-02-03')} />
import {today} from '@internationalized/date';

<MyDatePicker
  label="Appointment date"
  minValue={today(getLocalTimeZone())}
  defaultValue={parseDate('2022-02-03')} />
import {today} from '@internationalized/date';

<MyDatePicker
  label="Appointment date"
  minValue={today(
    getLocalTimeZone()
  )}
  defaultValue={parseDate(
    '2022-02-03'
  )}

Unavailable dates#

DatePicker supports marking certain dates as unavailable. These dates remain focusable with the keyboard in the calendar so that navigation is consistent, but cannot be selected by the user. When an unavailable date is entered into the date field, it is marked as invalid. The isDateUnavailable prop accepts a callback that is called to evaluate whether each visible date is unavailable.

This example includes multiple unavailable date ranges, e.g. dates when no appointments are available. In addition, all weekends are unavailable. The minValue prop is also used to prevent selecting dates before today.

import {isWeekend, today} from '@internationalized/date';
import {useLocale} from '@react-aria/i18n';

function Example() {
  let now = today(getLocalTimeZone());
  let disabledRanges = [
    [now, now.add({ days: 5 })],
    [now.add({ days: 14 }), now.add({ days: 16 })],
    [now.add({ days: 23 }), now.add({ days: 24 })]
  ];

  let { locale } = useLocale();
  let isDateUnavailable = (date: DateValue) =>
    isWeekend(date, locale) ||
    disabledRanges.some((interval) =>
      date.compare(interval[0]) >= 0 && date.compare(interval[1]) <= 0
    );

  return (
    <MyDatePicker
      label="Appointment date"
      minValue={today(getLocalTimeZone())}
      isDateUnavailable={isDateUnavailable}
    />
  );
}
import {isWeekend, today} from '@internationalized/date';
import {useLocale} from '@react-aria/i18n';

function Example() {
  let now = today(getLocalTimeZone());
  let disabledRanges = [
    [now, now.add({ days: 5 })],
    [now.add({ days: 14 }), now.add({ days: 16 })],
    [now.add({ days: 23 }), now.add({ days: 24 })]
  ];

  let { locale } = useLocale();
  let isDateUnavailable = (date: DateValue) =>
    isWeekend(date, locale) ||
    disabledRanges.some((interval) =>
      date.compare(interval[0]) >= 0 &&
      date.compare(interval[1]) <= 0
    );

  return (
    <MyDatePicker
      label="Appointment date"
      minValue={today(getLocalTimeZone())}
      isDateUnavailable={isDateUnavailable}
    />
  );
}
import {
  isWeekend,
  today
} from '@internationalized/date';
import {useLocale} from '@react-aria/i18n';

function Example() {
  let now = today(
    getLocalTimeZone()
  );
  let disabledRanges = [
    [
      now,
      now.add({
        days: 5
      })
    ],
    [
      now.add({
        days: 14
      }),
      now.add({
        days: 16
      })
    ],
    [
      now.add({
        days: 23
      }),
      now.add({
        days: 24
      })
    ]
  ];

  let { locale } =
    useLocale();
  let isDateUnavailable =
    (date: DateValue) =>
      isWeekend(
        date,
        locale
      ) ||
      disabledRanges
        .some((
          interval
        ) =>
          date.compare(
              interval[0]
            ) >= 0 &&
          date.compare(
              interval[1]
            ) <= 0
        );

  return (
    <MyDatePicker
      label="Appointment date"
      minValue={today(
        getLocalTimeZone()
      )}
      isDateUnavailable={isDateUnavailable}
    />
  );
}

Help text#

The description slot can be used to associate additional help text with a date picker. Additionally, the errorMessage slot can be used to help the user fix a validation error. It should be combined with the validationState prop to semantically mark the date picker as invalid for assistive technologies.

This example validates that the selected date is a weekday and not a weekend according to the current locale.

import {today, isWeekend} from '@internationalized/date';
import {useLocale} from 'react-aria';

function Example() {
  let [date, setDate] = React.useState(today(getLocalTimeZone()));
  let {locale} = useLocale();
  let isInvalid = isWeekend(date, locale);

  return (
    <MyDatePicker
      label="Appointment date"
      value={date}
      onChange={setDate}
      validationState={isInvalid ? 'invalid' : 'valid'}
      description={isInvalid ? undefined : 'Select a weekday'}
      errorMessage={isInvalid ? 'We are closed on weekends' : undefined} />
  );
}
import {isWeekend, today} from '@internationalized/date';
import {useLocale} from 'react-aria';

function Example() {
  let [date, setDate] = React.useState(
    today(getLocalTimeZone())
  );
  let { locale } = useLocale();
  let isInvalid = isWeekend(date, locale);

  return (
    <MyDatePicker
      label="Appointment date"
      value={date}
      onChange={setDate}
      validationState={isInvalid ? 'invalid' : 'valid'}
      description={isInvalid
        ? undefined
        : 'Select a weekday'}
      errorMessage={isInvalid
        ? 'We are closed on weekends'
        : undefined}
    />
  );
}
import {
  isWeekend,
  today
} from '@internationalized/date';
import {useLocale} from 'react-aria';

function Example() {
  let [date, setDate] =
    React.useState(
      today(
        getLocalTimeZone()
      )
    );
  let { locale } =
    useLocale();
  let isInvalid =
    isWeekend(
      date,
      locale
    );

  return (
    <MyDatePicker
      label="Appointment date"
      value={date}
      onChange={setDate}
      validationState={isInvalid
        ? 'invalid'
        : 'valid'}
      description={isInvalid
        ? undefined
        : 'Select a weekday'}
      errorMessage={isInvalid
        ? 'We are closed on weekends'
        : undefined}
    />
  );
}

Placeholder value#

When no value is set, a placeholder is shown. The format of the placeholder is influenced by the granularity and placeholderValue props. placeholderValue also controls the default values of each segment when the user first interacts with them, e.g. using the up and down arrow keys, as well as the default month shown in the calendar popover. By default, the placeholderValue is the current date at midnight, but you can set it to a more appropriate value if needed.

import {CalendarDate} from '@internationalized/date';

<MyDatePicker
  label="Birth date"
  placeholderValue={new CalendarDate(1980, 1, 1)}
/>
import {CalendarDate} from '@internationalized/date';

<MyDatePicker
  label="Birth date"
  placeholderValue={new CalendarDate(1980, 1, 1)}
/>
import {CalendarDate} from '@internationalized/date';

<MyDatePicker
  label="Birth date"
  placeholderValue={new CalendarDate(
    1980,
    1,
    1
  )}
/>

Hide time zone#

When a ZonedDateTime object is provided as the value to DatePicker, the time zone abbreviation is displayed by default. However, if this is displayed elsewhere or implicit based on the usecase, it can be hidden using the hideTimeZone option.

<MyDatePicker
  label="Appointment time"
  defaultValue={parseZonedDateTime('2022-11-07T10:45[America/Los_Angeles]')}
  hideTimeZone />
<MyDatePicker
  label="Appointment time"
  defaultValue={parseZonedDateTime(
    '2022-11-07T10:45[America/Los_Angeles]'
  )}
  hideTimeZone
/>
<MyDatePicker
  label="Appointment time"
  defaultValue={parseZonedDateTime(
    '2022-11-07T10:45[America/Los_Angeles]'
  )}
  hideTimeZone
/>

Hour cycle#

By default, DatePicker displays times in either 12 or 24 hour hour format depending on the user's locale. However, this can be overridden using the hourCycle prop if needed for a specific usecase. This example forces DatePicker to use 24-hour time, regardless of the locale.

<MyDatePicker
  label="Appointment time"
  granularity="minute"
  hourCycle={24} />
<MyDatePicker
  label="Appointment time"
  granularity="minute"
  hourCycle={24} />
<MyDatePicker
  label="Appointment time"
  granularity="minute"
  hourCycle={24}
/>

Advanced customization#


Composition#

If you need to customize one of the components within a DatePicker, such as Label or DateSegment, in many cases you can create a wrapper component. This lets you customize the props passed to the component.

function MyDateSegment(props) {
  return <MyDateSegment {...props} className="my-date-segment" />
}
function MyDateSegment(props) {
  return (
    <MyDateSegment {...props} className="my-date-segment" />
  );
}
function MyDateSegment(
  props
) {
  return (
    <MyDateSegment
      {...props}
      className="my-date-segment"
    />
  );
}

Hooks#

If you need to customize things even further, such as accessing internal state or customizing DOM structure, you can drop down to the lower level Hook-based API. DatePicker sends props to its child elements via public React contexts for each component. You can use this context to implement replacements for any component, using hooks from react-aria. This allows you to replace only the components you need to customize, and keep using the others.

DatePicker uses the following hooks. See the linked documentation for more details.

To replace a component used within a DatePicker, create your own component and use the useContextProps hook to merge the local props and ref with the ones sent via context by DatePicker. This example shows how you could implement a custom Calendar component that works with DatePicker.

import {CalendarContext, useContextProps} from 'react-aria-components';
import {useCalendar} from 'react-aria';

function MyCalendar(props) {
  // Merge local props and ref with props from context.
  let ref = React.useRef();
  [props, ref] = useContextProps(props, ref, CalendarContext);

  // Call useCalendarState and useCalendar.
  let state = useCalendarState({...props});
  let {calendarProps} = useCalendar(props, state, ref);

  // Render stuff
  // ...
}
import {
  CalendarContext,
  useContextProps
} from 'react-aria-components';
import {useCalendar} from 'react-aria';

function MyCalendar(props) {
  // Merge local props and ref with props from context.
  let ref = React.useRef();
  [props, ref] = useContextProps(
    props,
    ref,
    CalendarContext
  );

  // Call useCalendarState and useCalendar.
  let state = useCalendarState({ ...props });
  let { calendarProps } = useCalendar(props, state, ref);

  // Render stuff
  // ...
}
import {
  CalendarContext,
  useContextProps
} from 'react-aria-components';
import {useCalendar} from 'react-aria';

function MyCalendar(
  props
) {
  // Merge local props and ref with props from context.
  let ref = React
    .useRef();
  [props, ref] =
    useContextProps(
      props,
      ref,
      CalendarContext
    );

  // Call useCalendarState and useCalendar.
  let state =
    useCalendarState({
      ...props
    });
  let { calendarProps } =
    useCalendar(
      props,
      state,
      ref
    );

  // Render stuff
  // ...
}

This also works the other way. If you need to customize DatePicker itself, but want to reuse the components it contains, you can do so by providing the necessary contexts. The Provider component is an easier way to send multiple contexts at once. You can look at the DatePicker source code for more details on how to set this up.

import {ButtonContext, CalendarContext, LabelContext, useDatePicker} from 'react-aria';
import {Provider} from 'react-aria-components';

function MyDatePicker(props) {
  // ...
  let ref = useRef(null);
  let {
    labelProps,
    buttonProps,
    calendarProps
    // ...
  } = useDatePicker({/* ... */});

  return (
    <Provider
      values={[
        [LabelContext, labelProps],
        [ButtonContext, buttonProps],
        [CalendarContext, calendarProps]
        // ...
      ]}
    >
      {props.children}
    </Provider>
  );
}
import {
  ButtonContext,
  CalendarContext,
  LabelContext,
  useDatePicker
} from 'react-aria';
import {Provider} from 'react-aria-components';

function MyDatePicker(props) {
  // ...
  let ref = useRef(null);
  let {
    labelProps,
    buttonProps,
    calendarProps
    // ...
  } = useDatePicker({/* ... */});

  return (
    <Provider
      values={[
        [LabelContext, labelProps],
        [ButtonContext, buttonProps],
        [CalendarContext, calendarProps]
        // ...
      ]}
    >
      {props.children}
    </Provider>
  );
}
import {
  ButtonContext,
  CalendarContext,
  LabelContext,
  useDatePicker
} from 'react-aria';
import {Provider} from 'react-aria-components';

function MyDatePicker(
  props
) {
  // ...
  let ref = useRef(null);
  let {
    labelProps,
    buttonProps,
    calendarProps
    // ...
  } = useDatePicker({
    /* ... */
  });

  return (
    <Provider
      values={[
        [
          LabelContext,
          labelProps
        ],
        [
          ButtonContext,
          buttonProps
        ],
        [
          CalendarContext,
          calendarProps
        ]
        // ...
      ]}
    >
      {props.children}
    </Provider>
  );
}
