<Calendar aria-label="Event date" />
<Calendar aria-label="Event date" />
Value#
A Calendar
has no selection by default. An initial, uncontrolled value can be provided to the Calendar
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.
Calendar
supports values with both date and time components, but only allows users to modify the date. By default, Calendar
will emit CalendarDate
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 date and preserving the time components.
import {parseDate} from '@internationalized/date';
function Example() {
let [value, setValue] = React.useState(parseDate('2020-02-03'));
return (
<Flex gap="size-300" wrap>
<Calendar
aria-label="Date (uncontrolled)"
defaultValue={parseDate('2020-02-03')} />
<Calendar
aria-label="Date (controlled)"
value={value}
onChange={setValue} />
</Flex>
);
}
import {parseDate} from '@internationalized/date';
function Example() {
let [value, setValue] = React.useState(
parseDate('2020-02-03')
);
return (
<Flex gap="size-300" wrap>
<Calendar
aria-label="Date (uncontrolled)"
defaultValue={parseDate('2020-02-03')}
/>
<Calendar
aria-label="Date (controlled)"
value={value}
onChange={setValue}
/>
</Flex>
);
}
import {parseDate} from '@internationalized/date';
function Example() {
let [value, setValue] =
React.useState(
parseDate(
'2020-02-03'
)
);
return (
<Flex
gap="size-300"
wrap
>
<Calendar
aria-label="Date (uncontrolled)"
defaultValue={parseDate(
'2020-02-03'
)}
/>
<Calendar
aria-label="Date (controlled)"
value={value}
onChange={setValue}
/>
</Flex>
);
}
International calendars#
Calendar
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 Provider
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 Calendar
in the Hindi language, using the Indian calendar. Dates emitted from onChange
are in the Gregorian calendar.
import {Provider} from '@adobe/react-spectrum';
function Example() {
let [date, setDate] = React.useState(null);
return (
<Provider locale="hi-IN-u-ca-indian">
<Calendar aria-label="Date" value={date} onChange={setDate} />
<p>Selected date: {date?.toString()}</p>
</Provider>
);
}
import {Provider} from '@adobe/react-spectrum';
function Example() {
let [date, setDate] = React.useState(null);
return (
<Provider locale="hi-IN-u-ca-indian">
<Calendar
aria-label="Date"
value={date}
onChange={setDate}
/>
<p>Selected date: {date?.toString()}</p>
</Provider>
);
}
import {Provider} from '@adobe/react-spectrum';
function Example() {
let [date, setDate] =
React.useState(null);
return (
<Provider locale="hi-IN-u-ca-indian">
<Calendar
aria-label="Date"
value={date}
onChange={setDate}
/>
<p>
Selected date:
{' '}
{date
?.toString()}
</p>
</Provider>
);
}
Labeling#
An aria-label must be provided to the Calendar
for accessibility. If it is labeled by a separate element, an aria-labelledby
prop must be provided using the id
of the labeling element instead.
Internationalization#
In order to internationalize a Calendar
, a localized string should be passed to the aria-label
prop. For languages that are read right-to-left (e.g. Hebrew and Arabic), the layout of the Calendar
is automatically flipped. Dates are automatically formatted using the current locale.
Events#
Calendar
accepts an onChange
prop which is triggered whenever a date is selected 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. 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 '@adobe/react-spectrum';
function Example() {
let [date, setDate] = React.useState(parseDate('2022-07-04'));
let formatter = useDateFormatter({dateStyle: 'full'});
return (
<>
<Calendar aria-label="Event date" value={date} onChange={setDate} />
<p>Selected date: {formatter.format(date.toDate(getLocalTimeZone()))}</p>
</>
);
}
import {getLocalTimeZone} from '@internationalized/date';
import {useDateFormatter} from '@adobe/react-spectrum';
function Example() {
let [date, setDate] = React.useState(
parseDate('2022-07-04')
);
let formatter = useDateFormatter({ dateStyle: 'full' });
return (
<>
<Calendar
aria-label="Event date"
value={date}
onChange={setDate}
/>
<p>
Selected date:{' '}
{formatter.format(date.toDate(getLocalTimeZone()))}
</p>
</>
);
}
import {getLocalTimeZone} from '@internationalized/date';
import {useDateFormatter} from '@adobe/react-spectrum';
function Example() {
let [date, setDate] =
React.useState(
parseDate(
'2022-07-04'
)
);
let formatter =
useDateFormatter({
dateStyle: 'full'
});
return (
<>
<Calendar
aria-label="Event date"
value={date}
onChange={setDate}
/>
<p>
Selected date:
{' '}
{formatter
.format(
date.toDate(
getLocalTimeZone()
)
)}
</p>
</>
);
}
Validation#
By default, Calendar
allows selecting any date. The minValue
and maxValue
props can also be used to prevent the user from selecting dates outside a certain range.
This example only accepts dates after today.
import {today} from '@internationalized/date';
<Calendar
aria-label="Appointment date"
minValue={today(getLocalTimeZone())}
/>
import {today} from '@internationalized/date';
<Calendar
aria-label="Appointment date"
minValue={today(getLocalTimeZone())}
/>
import {today} from '@internationalized/date';
<Calendar
aria-label="Appointment date"
minValue={today(
getLocalTimeZone()
)}
/>
Unavailable dates#
Calendar
supports marking certain dates as unavailable. These dates cannot be selected by the user and are displayed with a crossed out appearance. 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 '@adobe/react-spectrum';
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) =>
isWeekend(date, locale) ||
disabledRanges.some((interval) =>
date.compare(interval[0]) >= 0 && date.compare(interval[1]) <= 0
);
return (
<Calendar
aria-label="Appointment date"
minValue={today(getLocalTimeZone())}
isDateUnavailable={isDateUnavailable}
/>
);
}
import {isWeekend, today} from '@internationalized/date';
import {useLocale} from '@adobe/react-spectrum';
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) =>
isWeekend(date, locale) ||
disabledRanges.some((interval) =>
date.compare(interval[0]) >= 0 &&
date.compare(interval[1]) <= 0
);
return (
<Calendar
aria-label="Appointment date"
minValue={today(getLocalTimeZone())}
isDateUnavailable={isDateUnavailable}
/>
);
}
import {
isWeekend,
today
} from '@internationalized/date';
import {useLocale} from '@adobe/react-spectrum';
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) =>
isWeekend(
date,
locale
) ||
disabledRanges
.some((
interval
) =>
date.compare(
interval[0]
) >= 0 &&
date.compare(
interval[1]
) <= 0
);
return (
<Calendar
aria-label="Appointment date"
minValue={today(
getLocalTimeZone()
)}
isDateUnavailable={isDateUnavailable}
/>
);
}
Controlling the focused date#
By default, the selected date is focused when a Calendar
first mounts. If no value
or defaultValue
prop is provided, then the current date is focused. However, Calendar
supports controlling which date is focused using the focusedValue
and onFocusChange
props. This also determines which month is visible. The defaultFocusedValue
prop allows setting the initial focused date when the Calendar
first mounts, without controlling it.
This example focuses July 1, 2021 by default. The user may change the focused date, and the onFocusChange
event updates the state. Clicking the button resets the focused date back to the initial value.
import {CalendarDate} from '@internationalized/date';
function Example() {
let defaultDate = new CalendarDate(2021, 7, 1);
let [focusedDate, setFocusedDate] = React.useState(defaultDate);
return (
<Flex direction="column" alignItems="start" gap="size-200">
<ActionButton onPress={() => setFocusedDate(defaultDate)}>
Reset focused date
</ActionButton>
<Calendar focusedValue={focusedDate} onFocusChange={setFocusedDate} />
</Flex>
);
}
import {CalendarDate} from '@internationalized/date';
function Example() {
let defaultDate = new CalendarDate(2021, 7, 1);
let [focusedDate, setFocusedDate] = React.useState(
defaultDate
);
return (
<Flex
direction="column"
alignItems="start"
gap="size-200"
>
<ActionButton
onPress={() => setFocusedDate(defaultDate)}
>
Reset focused date
</ActionButton>
<Calendar
focusedValue={focusedDate}
onFocusChange={setFocusedDate}
/>
</Flex>
);
}
import {CalendarDate} from '@internationalized/date';
function Example() {
let defaultDate =
new CalendarDate(
2021,
7,
1
);
let [
focusedDate,
setFocusedDate
] = React.useState(
defaultDate
);
return (
<Flex
direction="column"
alignItems="start"
gap="size-200"
>
<ActionButton
onPress={() =>
setFocusedDate(
defaultDate
)}
>
Reset focused
date
</ActionButton>
<Calendar
focusedValue={focusedDate}
onFocusChange={setFocusedDate}
/>
</Flex>
);
}

Visual options#
Disabled#
<Calendar aria-label="Event date" isDisabled />
<Calendar aria-label="Event date" isDisabled />
<Calendar
aria-label="Event date"
isDisabled
/>
Read only#
The isReadOnly
boolean prop makes the Calendar's value immutable. Unlike isDisabled
, the Calendar remains focusable.
<Calendar
aria-label="Event date"
value={today(getLocalTimeZone())}
isReadOnly
/>
<Calendar
aria-label="Event date"
value={today(getLocalTimeZone())}
isReadOnly
/>
<Calendar
aria-label="Event date"
value={today(
getLocalTimeZone()
)}
isReadOnly
/>
Visible months#
By default, the Calendar
displays a single month. The visibleMonths
prop allows displaying up to 3 months at a time.
<div style={{maxWidth: '100%', overflow: 'auto'}}>
<Calendar aria-label="Event date" visibleMonths={3} />
</div>
<div style={{maxWidth: '100%', overflow: 'auto'}}>
<Calendar aria-label="Event date" visibleMonths={3} />
</div>
<div
style={{
maxWidth: '100%',
overflow: 'auto'
}}
>
<Calendar
aria-label="Event date"
visibleMonths={3}
/>
</div>
Page behavior#
By default, when pressing the next or previous buttons, pagination will advance by the visibleMonths
value. This behavior can be changed to page by single months instead, by setting pageBehavior
to single
.
<div style={{maxWidth: '100%', overflow: 'auto'}}>
<Calendar aria-label="Event date" visibleMonths={3} pageBehavior="single" />
</div>
<div style={{ maxWidth: '100%', overflow: 'auto' }}>
<Calendar
aria-label="Event date"
visibleMonths={3}
pageBehavior="single"
/>
</div>
<div
style={{
maxWidth: '100%',
overflow: 'auto'
}}
>
<Calendar
aria-label="Event date"
visibleMonths={3}
pageBehavior="single"
/>
</div>
