Features#

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

International – Support for locale-specific formatting, number systems, hour cycles, and right-to-left layout.
Time zone aware – Times can optionally include a time zone. All modifications follow time zone rules such as daylight saving time.
Accessible – Each time unit is displayed as an individually focusable and editable segment, which allows users an easy way to edit times using the keyboard, in any format and locale.
Touch friendly – Time segments are editable using an easy to use numeric keypad, and all interactions are accessible using touch-based screen readers.
Validation – Integrates with HTML forms, supporting required, minimum and maximum values, custom validation functions, realtime validation, and server-side validation errors.
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 TimeField.

Anatomy#

A time field consists of a label, and a group of segments representing each unit of a time (e.g. hours, minutes, and seconds). Each segment is individually focusable and editable by the user, by typing or using the arrow keys to increment and decrement the value. This approach allows values to be formatted and parsed correctly regardless of the locale or time format, and offers an easy and error-free way to edit times using the keyboard.

TimeField 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.

import {DateInput, DateSegment, FieldError, Label, Text, TimeField} from 'react-aria-components';

<TimeField>
  <Label />
  <DateInput>
    {(segment) => <DateSegment segment={segment} />}
  </DateInput>
  <Text slot="description" />
  <FieldError />
</TimeField>

import {
  DateInput,
  DateSegment,
  FieldError,
  Label,
  Text,
  TimeField
} from 'react-aria-components';

<TimeField>
  <Label />
  <DateInput>
    {(segment) => <DateSegment segment={segment} />}
  </DateInput>
  <Text slot="description" />
  <FieldError />
</TimeField>

import {
  DateInput,
  DateSegment,
  FieldError,
  Label,
  Text,
  TimeField
} from 'react-aria-components';

<TimeField>
  <Label />
  <DateInput>
    {(segment) => (
      <DateSegment
        segment={segment}
      />
    )}
  </DateInput>
  <Text slot="description" />
  <FieldError />
</TimeField>

If the time field 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 DateField, so you can reuse many components between them if you have both.

Concepts#

TimeField makes use of the following concepts:

@internationalized/date

Represent and manipulate dates and times in a locale-aware manner.

Forms

Validating and submitting form data, and integrating with form libraries.

Composed components#

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

Label

A label provides context for an input element.

Starter kits#

To help kick-start your project, we offer starter kits that include example implementations of all React Aria components with various styling solutions. All components are fully styled, including support for dark mode, high contrast mode, and all UI states. Each starter comes with a pre-configured Storybook that you can experiment with, or use as a starting point for your own component library.

Reusable wrappers#

If you will use a TimeField 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 TimeField 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 slot to render help text, and FieldError component to render validation errors.

import type {TimeFieldProps, TimeValue, ValidationResult} from 'react-aria-components';
import {FieldError, Text} from 'react-aria-components';

interface MyTimeFieldProps<T extends TimeValue> extends TimeFieldProps<T> {
  label?: string;
  description?: string;
  errorMessage?: string | ((validation: ValidationResult) => string);
}

function MyTimeField<T extends TimeValue>(
  { label, description, errorMessage, ...props }: MyTimeFieldProps<T>
) {
  return (
    <TimeField {...props}>
      <Label>{label}</Label>
      <DateInput>
        {(segment) => <DateSegment segment={segment} />}
      </DateInput>
      {description && <Text slot="description">{description}</Text>}
      <FieldError>{errorMessage}</FieldError>
    </TimeField>
  );
}

      </DateInput>
      {description && (
        <Text slot="description">{description}</Text>
      )}
      <FieldError>{errorMessage}</FieldError>
    </TimeField>
  );
}

    | ((
      validation:
        ValidationResult
    ) => string);
}

function MyTimeField<
  T extends TimeValue
>({
  label,
  description,
  errorMessage,
  ...props
}: MyTimeFieldProps<T>) {
  return (
    <TimeField
      {...props}
    >
      <Label>
        {label}
      </Label>
      <DateInput>
        {(segment) => (
          <DateSegment
            segment={segment}
          />
        )}
      </DateInput>
      {description && (
        <Text slot="description">
          {description}
        </Text>
      )}
      <FieldError>
        {errorMessage}
      </FieldError>
    </TimeField>
  );
}

<MyTimeField label="Event time" />

Value#

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

Time values are provided using objects in the @internationalized/date package. This library handles correct international date and time manipulation across calendars, time zones, and other localization concerns.

TimeField only supports selecting times, but values with date components are also accepted. By default, TimeField will emit Time objects in the onChange event, but if a CalendarDateTime or ZonedDateTime object is passed as the value or defaultValue, values of that type will be emitted, changing only the time and preserving the date components.

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

function Example() {
  let [value, setValue] = React.useState(new Time(11, 45));

  return (
    <>
      <MyTimeField
        label="Time (uncontrolled)"
        defaultValue={new Time(11, 45)} />
      <MyTimeField
        label="Time (controlled)"
        value={value}
        onChange={setValue} />
    </>
  );
}

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

function Example() {
  let [value, setValue] = React.useState(new Time(11, 45));

  return (
    <>
      <MyTimeField
        label="Time (uncontrolled)"
        defaultValue={new Time(11, 45)} />
      <MyTimeField
        label="Time (controlled)"
        value={value}
        onChange={setValue} />
    </>
  );
}

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

function Example() {
  let [value, setValue] =
    React.useState(
      new Time(11, 45)
    );

  return (
    <>
      <MyTimeField
        label="Time (uncontrolled)"
        defaultValue={new Time(
          11,
          45
        )}
      />
      <MyTimeField
        label="Time (controlled)"
        value={value}
        onChange={setValue}
      />
    </>
  );
}

Time values may also be parsed from strings using the parseTime function. This accepts ISO 8601 formatted time strings such as "04:45:23.123". The toString method of a Time object can also be used to convert a time object to a string.

Time zones#

TimeField 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';

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

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

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

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

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

TimeField 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';

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

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

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

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

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

Granularity#

The granularity prop allows you to control the smallest unit that is displayed by TimeField. By default, times are displayed with "minute" granularity. More granular time values can be displayed by setting the granularity prop to "second".

<MyTimeField
  label="Event time"
  granularity="second"  defaultValue={parseAbsoluteToLocal('2021-04-07T18:45:22Z')} />

<MyTimeField
  label="Event time"
  granularity="second"  defaultValue={parseAbsoluteToLocal(
    '2021-04-07T18:45:22Z'
  )}
/>

<MyTimeField
  label="Event time"
  granularity="second"  defaultValue={parseAbsoluteToLocal(
    '2021-04-07T18:45:22Z'
  )}
/>

HTML forms#

TimeField supports the name prop for integration with HTML forms. The value will be submitted to the server as an ISO 8601 formatted string, e.g. "08:45:00".

<MyTimeField label="Meeting time" name="meetingTime" />

<MyTimeField label="Meeting time" name="meetingTime" />

<MyTimeField
  label="Meeting time"
  name="meetingTime"
/>

Events#

TimeField accepts an onChange prop which is triggered whenever the time 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. TimeField allows editing the time components while keeping the date fixed.

import {useDateFormatter} from 'react-aria';

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

  return (
    <>
      <MyTimeField label="Time" value={date} onChange={setDate} />
      <p>
        Selected date and time:{' '}
        {(date?.toDate && formatter.format(date.toDate())) ||
          (date && date.toString()) || '--'}
      </p>
    </>
  );
}

import {useDateFormatter} from 'react-aria';

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

  return (
    <>
      <MyTimeField
        label="Time"
        value={date}
        onChange={setDate}
      />
      <p>
        Selected date and time:{' '}
        {(date?.toDate &&
          formatter.format(date.toDate())) ||
          (date && date.toString()) || '--'}
      </p>
    </>
  );
}

import {useDateFormatter} from 'react-aria';

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

  return (
    <>
      <MyTimeField
        label="Time"
        value={date}
        onChange={setDate}
      />
      <p>
        Selected date and
        time:{' '}
        {(date?.toDate &&
          formatter
            .format(
              date
                .toDate()
            )) ||
          (date &&
            date
              .toString()) ||
          '--'}
      </p>
    </>
  );
}

Validation#

TimeField supports the isRequired prop to ensure the user enters a value, as well as minimum and maximum values, and custom client and server-side validation. It can also be integrated with other form libraries. See the Forms guide to learn more.

To display validation errors, add a <FieldError> element as a child of the TimeField. This allows you to render error messages from all of the above sources with consistent custom styles.

import {Form, FieldError, Button} from 'react-aria-components';

<Form>
  <TimeField name="time" isRequired>    <Label>Meeting time</Label>
    <DateInput>
      {segment => <DateSegment segment={segment} />}
    </DateInput>
    <FieldError />  </TimeField>
  <Button type="submit">Submit</Button>
</Form>

import {
  Button,
  FieldError,
  Form
} from 'react-aria-components';

<Form>
  <TimeField name="time" isRequired>    <Label>Meeting time</Label>
    <DateInput>
      {(segment) => <DateSegment segment={segment} />}
    </DateInput>
    <FieldError />  </TimeField>
  <Button type="submit">Submit</Button>
</Form>

import {
  Button,
  FieldError,
  Form
} from 'react-aria-components';

<Form>
  <TimeField
    name="time"
    isRequired
  >    <Label>
      Meeting time
    </Label>
    <DateInput>
      {(segment) => (
        <DateSegment
          segment={segment}
        />
      )}
    </DateInput>
    <FieldError />  </TimeField>
  <Button type="submit">
    Submit
  </Button>
</Form>

  }
}

.react-aria-TimeField {
  .react-aria-FieldError {
    font-size: 12px;
    color: var(--invalid-color);
  }
}

By default, FieldError displays default validation messages provided by the browser. See Customizing error messages in the Forms guide to learn how to provide your own custom errors.

Minimum and maximum values#

The minValue and maxValue props can also be used to ensure the value is within a specific range. This example only accepts times between 9 AM and 5 PM.

<Form>
  <MyTimeField
    label="Meeting time"
    minValue={new Time(9)}
    maxValue={new Time(17)}    defaultValue={new Time(8)} />
  <Button type="submit">Submit</Button>
</Form>

<Form>
  <MyTimeField
    label="Meeting time"
    minValue={new Time(9)}
    maxValue={new Time(17)}    defaultValue={new Time(8)} />
  <Button type="submit">Submit</Button>
</Form>

<Form>
  <MyTimeField
    label="Meeting time"
    minValue={new Time(
      9
    )}
    maxValue={new Time(
      17
    )}    defaultValue={new Time(
      8
    )}
  />
  <Button type="submit">
    Submit
  </Button>
</Form>

The validate function can be used to perform custom validation logic. It receives the current field value, and should return a string or array of strings representing one or more error messages if the value is invalid.

This example validates that the selected time is on a 15 minute increment.

<Form>
  <MyTimeField
    label="Meeting time"
    validate={(time) =>
      time?.minute % 15 !== 0 ? 'Meetings start every 15 minutes.' : null}    defaultValue={new Time(9, 25)}
  />
  <Button type="submit">Submit</Button>
</Form>

<Form>
  <MyTimeField
    label="Meeting time"
    validate={(time) =>
      time?.minute % 15 !== 0
        ? 'Meetings start every 15 minutes.'
        : null}    defaultValue={new Time(9, 25)}
  />
  <Button type="submit">Submit</Button>
</Form>

<Form>
  <MyTimeField
    label="Meeting time"
    validate={(time) =>
      time?.minute %
            15 !== 0
        ? 'Meetings start every 15 minutes.'
        : null}    defaultValue={new Time(
      9,
      25
    )}
  />
  <Button type="submit">
    Submit
  </Button>
</Form>

Description#

The description slot can be used to associate additional help text with a date field.

<TimeField>
  <Label>Appointment time</Label>
  <DateInput>
    {segment => <DateSegment segment={segment} />}
  </DateInput>
  <Text slot="description">Please select a time between 9 AM and 5 PM.</Text></TimeField>

<TimeField>
  <Label>Appointment time</Label>
  <DateInput>
    {(segment) => <DateSegment segment={segment} />}
  </DateInput>
  <Text slot="description">
    Please select a time between 9 AM and 5 PM.
  </Text></TimeField>

<TimeField>
  <Label>
    Appointment time
  </Label>
  <DateInput>
    {(segment) => (
      <DateSegment
        segment={segment}
      />
    )}
  </DateInput>
  <Text slot="description">
    Please select a
    time between 9 AM
    and 5 PM.
  </Text></TimeField>

Format options#

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. By default, the placeholderValue is midnight, but you can set it to a more appropriate value if needed.

<MyTimeField label="Meeting time" placeholderValue={new Time(9)} />

<MyTimeField
  label="Meeting time"
  placeholderValue={new Time(9)}
/>

<MyTimeField
  label="Meeting time"
  placeholderValue={new Time(
    9
  )}
/>

Hide time zone#

When a ZonedDateTime object is provided as the value to TimeField, 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.

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

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

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

Hour cycle#

By default, TimeField 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 TimeField to use 24-hour time, regardless of the locale.

<MyTimeField
  label="Appointment time"
  hourCycle={24} />

<MyTimeField
  label="Appointment time"
  hourCycle={24} />

<MyTimeField
  label="Appointment time"
  hourCycle={24}
/>

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-TimeField {
  /* ... */
}

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

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

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 data attributes, which you can target in CSS selectors. For example:

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

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

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

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

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

.react-aria-DateSegment[data-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>

The states, selectors, and render props for each component used in a TimeField are documented below.

TimeField#

Name	CSS Selector	Description
`state`	`—`	State of the date field.
`isInvalid`	`[data-invalid]`	Whether the date field is invalid.
`isDisabled`	`[data-disabled]`	Whether the date field is disabled.

Label#

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

`isInvalid`	Whether the input value is invalid.
`validationErrors`	The current error messages for the input if it is invalid, otherwise an empty array.
`validationDetails`	The native validation details for the input.

Advanced customization#

Composition#

If you need to customize one of the components within a TimeField, 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"
    />
  );
}

Contexts#

All React Aria Components export a corresponding context that can be used to send props to them from a parent element. This enables you to build your own compositional APIs similar to those found in React Aria Components itself. You can send any prop or ref via context that you could pass to the corresponding component. The local props and ref on the component are merged with the ones passed via context, with the local props taking precedence (following the rules documented in mergeProps).

Component	Context	Props	Ref
`TimeField`	`TimeFieldContext`	`TimeFieldProps`	`HTMLDivElement`

This example shows a FieldGroup component that renders a group of time fields with a title and optional error message. It uses the useId hook to generate a unique id for the error message. All of the child TimeFields are marked invalid and associated with the error message via the aria-describedby attribute passed to the TimeFieldContext provider.

import {TimeFieldContext} from 'react-aria-components';
import {useId} from 'react-aria';

interface FieldGroupProps {
  title?: string;
  children?: React.ReactNode;
  errorMessage?: string;
}

function FieldGroup({ title, children, errorMessage }: FieldGroupProps) {
  let errorId = useId();
  return (
    <fieldset>
      <legend>{title}</legend>
      <TimeFieldContext.Provider
        value={{
          isInvalid: !!errorMessage,
          'aria-describedby': errorMessage ? errorId : undefined
        }}
      >        {children}
      </TimeFieldContext.Provider>
      {errorMessage && (
        <small id={errorId} className="invalid">{errorMessage}</small>
      )}
    </fieldset>
  );
}

<FieldGroup
  title="Schedule meeting time"
  errorMessage="End time must be after start time."
>
  <MyTimeField label="Start" defaultValue={new Time(13)} />
  <MyTimeField label="End" defaultValue={new Time(9)} />
</FieldGroup>

import {TimeFieldContext} from 'react-aria-components';
import {useId} from 'react-aria';

interface FieldGroupProps {
  title?: string;
  children?: React.ReactNode;
  errorMessage?: string;
}

function FieldGroup(
  { title, children, errorMessage }: FieldGroupProps
) {
  let errorId = useId();
  return (
    <fieldset>
      <legend>{title}</legend>
      <TimeFieldContext.Provider
        value={{
          isInvalid: !!errorMessage,
          'aria-describedby': errorMessage
            ? errorId
            : undefined
        }}
      >        {children}
      </TimeFieldContext.Provider>
      {errorMessage && (
        <small id={errorId} className="invalid">
          {errorMessage}
        </small>
      )}
    </fieldset>
  );
}

<FieldGroup
  title="Schedule meeting time"
  errorMessage="End time must be after start time."
>
  <MyTimeField
    label="Start"
    defaultValue={new Time(13)}
  />
  <MyTimeField label="End" defaultValue={new Time(9)} />
</FieldGroup>

import {TimeFieldContext} from 'react-aria-components';
import {useId} from 'react-aria';

interface FieldGroupProps {
  title?: string;
  children?:
    React.ReactNode;
  errorMessage?: string;
}

function FieldGroup(
  {
    title,
    children,
    errorMessage
  }: FieldGroupProps
) {
  let errorId = useId();
  return (
    <fieldset>
      <legend>
        {title}
      </legend>
      <TimeFieldContext.Provider
        value={{
          isInvalid:
            !!errorMessage,
          'aria-describedby':
            errorMessage
              ? errorId
              : undefined
        }}
      >        {children}

        <small
          id={errorId}
          className="invalid"
        >
          {errorMessage}
        </small>
      )}
    </fieldset>
  );
}

    defaultValue={new Time(
      9

Custom children#

TimeField passes props to its child components, such as the label, via their associated contexts. These contexts are exported so you can also consume them in your own custom components. This enables you to reuse existing components from your app or component library together with React Aria Components.

Component	Context	Props	Ref
`Label`	`LabelContext`	`LabelProps`	`HTMLLabelElement`
`Text`	`TextContext`	`TextProps`	`HTMLElement`

This example consumes from LabelContext in an existing styled label component to make it compatible with React Aria Components. The useContextProps hook merges the local props and ref with the ones provided via context by TimeField.

import type {LabelProps} from 'react-aria-components';
import {LabelContext, useContextProps} from 'react-aria-components';

const MyCustomLabel = React.forwardRef(
  (props: LabelProps, ref: React.ForwardedRef<HTMLLabelElement>) => {
    // Merge the local props and ref with the ones provided via context.
    [props, ref] = useContextProps(props, ref, LabelContext);
    // ... your existing Label component
    return <label {...props} ref={ref} />;
  }
);

import type {LabelProps} from 'react-aria-components';
import {
  LabelContext,
  useContextProps
} from 'react-aria-components';

const MyCustomLabel = React.forwardRef(
  (
    props: LabelProps,
    ref: React.ForwardedRef<HTMLLabelElement>
  ) => {
    // Merge the local props and ref with the ones provided via context.
    [props, ref] = useContextProps(
      props,
      ref,
      LabelContext
    );
    // ... your existing Label component
    return <label {...props} ref={ref} />;
  }
);

import type {LabelProps} from 'react-aria-components';
import {
  LabelContext,
  useContextProps
} from 'react-aria-components';

const MyCustomLabel =
  React.forwardRef(
    (
      props: LabelProps,
      ref:
        React.ForwardedRef<
          HTMLLabelElement
        >
    ) => {
      // Merge the local props and ref with the ones provided via context.
      [props, ref] =
        useContextProps(
          props,
          ref,
          LabelContext
        );
      // ... your existing Label component
      return (
        <label
          {...props}
          ref={ref}
        />
      );
    }
  );

Now you can use MyCustomLabel within a TimeField, in place of the builtin React Aria Components Label.

<TimeField>
  <MyCustomLabel>Name</MyCustomLabel>  <DateInput>
    {segment => <DateSegment segment={segment} />}
  </DateInput>
</TimeField>

<TimeField>
  <MyCustomLabel>Name</MyCustomLabel>  <DateInput>
    {segment => <DateSegment segment={segment} />}
  </DateInput>
</TimeField>

<TimeField>
  <MyCustomLabel>
    Name
  </MyCustomLabel>  <DateInput>
    {(segment) => (

State#

TimeField provides a TimeFieldState object to its children via TimeFieldStateContext. This can be used to access and manipulate the time field's state.

This example shows a TimeZoneName component that can be placed within a TimeField to display the full time zone name.

import {TimeFieldStateContext} from 'react-aria-components';
import {useDateFormatter} from 'react-aria';

function TimeZoneName() {
  let state = React.useContext(TimeFieldStateContext)!;  if ('timeZone' in state.value) {
    let formatter = useDateFormatter({
      timeZoneName: 'long',
      timeZone: state.value.timeZone
    });
    let timeZone = formatter
      .formatToParts(state.value.toDate())
      .find((p) => p.type === 'timeZoneName').value;
    return <small>{timeZone}</small>;
  }
  return null;
}

Methods

Method	Description
`setValue( (value: DateValue \| \| null )): void`	Sets the field's value.
`increment( (type: SegmentType )): void`	Increments the given segment. Upon reaching the minimum or maximum value, the value wraps around to the opposite limit.
`decrement( (type: SegmentType )): void`	Decrements the given segment. Upon reaching the minimum or maximum value, the value wraps around to the opposite limit.
`incrementPage( (type: SegmentType )): void`	Increments the given segment by a larger amount, rounding it to the nearest increment. The amount to increment by depends on the field, for example 15 minutes, 7 days, and 5 years. Upon reaching the minimum or maximum value, the value wraps around to the opposite limit.
`decrementPage( (type: SegmentType )): void`	Decrements the given segment by a larger amount, rounding it to the nearest increment. The amount to decrement by depends on the field, for example 15 minutes, 7 days, and 5 years. Upon reaching the minimum or maximum value, the value wraps around to the opposite limit.
