DateField
A date field allows users to enter and edit date and time values using a keyboard. Each part of a date value is displayed in an individually editable segment.

Features#
A date field 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. DateField
helps achieve accessible and international date and time fields 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.
- Touch friendly – Date 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 DateField
.
Anatomy#
A date field consists of a label, and a group of segments representing each unit of a date and time (e.g. years, months, days, etc.). 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 date format, and offers an easy and error-free way to edit dates using the keyboard.
DateField
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 {DateField, DateInput, DateSegment, FieldError, Label, Text} from 'react-aria-components';
<DateField>
<Label />
<DateInput>
{(segment) => <DateSegment segment={segment} />}
</DateInput>
<Text slot="description" />
<FieldError />
</DateField>
import {
DateField,
DateInput,
DateSegment,
FieldError,
Label,
Text
} from 'react-aria-components';
<DateField>
<Label />
<DateInput>
{(segment) => <DateSegment segment={segment} />}
</DateInput>
<Text slot="description" />
<FieldError />
</DateField>
import {
DateField,
DateInput,
DateSegment,
FieldError,
Label,
Text
} from 'react-aria-components';
<DateField>
<Label />
<DateInput>
{(segment) => (
<DateSegment
segment={segment}
/>
)}
</DateInput>
<Text slot="description" />
<FieldError />
</DateField>
If the date 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 TimeField, so you can reuse many components between them if you have both.
Concepts#
DateField
makes use of the following concepts:
Composed components#
A DateField
uses the following components, which may also be used standalone or reused in other components.
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 DateField 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 DateField
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 {DateFieldProps, DateValue, ValidationResult} from 'react-aria-components';
import {FieldError, Text} from 'react-aria-components';
interface MyDateFieldProps<T extends DateValue> extends DateFieldProps<T> {
label?: string;

Value#
A DateField
displays a placeholder by default. An initial, uncontrolled value can be provided to the DateField
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. DateField
supports values of the following types:
CalendarDate
– a date without any time components. May be parsed from a string representation using theparseDate
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 theparseDateTime
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 aZonedDateTime
.ZonedDateTime
– a date with a time in a specific time zone. May be parsed from a string representation using theparseZonedDateTime
,parseAbsolute
, orparseAbsoluteToLocal
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 (
<>
<MyDateField
label="Date (uncontrolled)"
defaultValue={parseDate('2020-02-03')} />
<MyDateField
label="Date (controlled)"
value={value}
onChange={setValue} />
</>
);
}
import {parseDate} from '@internationalized/date';
function Example() {
let [value, setValue] = React.useState(
parseDate('2020-02-03')
);
return (
<>
<MyDateField
label="Date (uncontrolled)"
defaultValue={parseDate('2020-02-03')}
/>
<MyDateField
label="Date (controlled)"
value={value}
onChange={setValue}
/>
</>
);
}
import {parseDate} from '@internationalized/date';
function Example() {
let [value, setValue] =
React.useState(
parseDate(
'2020-02-03'
)
);
return (
<>
<MyDateField
label="Date (uncontrolled)"
defaultValue={parseDate(
'2020-02-03'
)}
/>
<MyDateField
label="Date (controlled)"
value={value}
onChange={setValue}
/>
</>
);
}
Time zones#
DateField
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 forparseAbsolute
, and accepts the same formats.
import {parseZonedDateTime} from '@internationalized/date';
<MyDateField
label="Event date"
defaultValue={parseZonedDateTime('2022-11-07T00:45[America/Los_Angeles]')}
/>
import {parseZonedDateTime} from '@internationalized/date';
<MyDateField
label="Event date"
defaultValue={parseZonedDateTime(
'2022-11-07T00:45[America/Los_Angeles]'
)}
/>
import {parseZonedDateTime} from '@internationalized/date';
<MyDateField
label="Event date"
defaultValue={parseZonedDateTime(
'2022-11-07T00:45[America/Los_Angeles]'
)}
/>
DateField
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';
<MyDateField
label="Event date"
defaultValue={parseAbsoluteToLocal('2021-11-07T07:45:00Z')}
/>
import {parseAbsoluteToLocal} from '@internationalized/date';
<MyDateField
label="Event date"
defaultValue={parseAbsoluteToLocal(
'2021-11-07T07:45:00Z'
)}
/>
import {parseAbsoluteToLocal} from '@internationalized/date';
<MyDateField
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 DateField
. 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 DateFields are synchronized with the same value, but display different granularities.
function Example() {
let [date, setDate] = React.useState(
parseAbsoluteToLocal('2021-04-07T18:45:22Z')
);
return (
<>
<MyDateField
label="Date and time"
granularity="second" value={date}
onChange={setDate}
/>
<MyDateField
label="Date"
granularity="day" value={date}
onChange={setDate}
/>
</>
);
}
function Example() {
let [date, setDate] = React.useState(
parseAbsoluteToLocal('2021-04-07T18:45:22Z')
);
return (
<>
<MyDateField
label="Date and time"
granularity="second" value={date}
onChange={setDate}
/>
<MyDateField
label="Date"
granularity="day" value={date}
onChange={setDate}
/>
</>
);
}
function Example() {
let [date, setDate] =
React.useState(
parseAbsoluteToLocal(
'2021-04-07T18:45:22Z'
)
);
return (
<>
<MyDateField
label="Date and time"
granularity="second" value={date}
onChange={setDate}
/>
<MyDateField
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';
<MyDateField
label="Event date"
granularity="second" />
<MyDateField
label="Event date"
placeholderValue={now('America/New_York')}
granularity="second" />
import {now} from '@internationalized/date';
<MyDateField
label="Event date"
granularity="second" />
<MyDateField
label="Event date"
placeholderValue={now('America/New_York')}
granularity="second" />
import {now} from '@internationalized/date';
<MyDateField
label="Event date"
granularity="second"
/>
<MyDateField
label="Event date"
placeholderValue={now(
'America/New_York'
)}
granularity="second"
/>
International calendars#
DateField
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 DateField
in the Hindi language, using the Indian calendar. Dates emitted from onChange
are in the Gregorian calendar.
import {I18nProvider} from 'react-aria';
function Example() {
let [date, setDate] = React.useState<DateValue | null>(null);
return (
<I18nProvider locale="hi-IN-u-ca-indian"> <MyDateField label="Date" value={date} onChange={setDate} />
<p>Selected date: {date?.toString()}</p>
</I18nProvider>
);
}
import {I18nProvider} from 'react-aria';
function Example() {
let [date, setDate] = React.useState<DateValue | null>(
null
);
return (
<I18nProvider locale="hi-IN-u-ca-indian"> <MyDateField
label="Date"
value={date}
onChange={setDate}
/>
<p>Selected date: {date?.toString()}</p>
</I18nProvider>
);
}
import {I18nProvider} from 'react-aria';
function Example() {
let [date, setDate] =
React.useState<
DateValue | null
>(null);
return (
<I18nProvider locale="hi-IN-u-ca-indian"> <MyDateField
label="Date"
value={date}
onChange={setDate}
/>
<p>
Selected date:
{' '}
{date
?.toString()}
</p>
</I18nProvider>
);
}
HTML forms#
DateField supports the name
prop for integration with HTML forms. The value will be submitted to the server as an ISO 8601 formatted string according to the granularity of the value. For example, if the date field allows selecting only a date then a string such as "2023-02-03"
will be submitted, and if it allows selecting a time then a string such as "2023-02-03T08:45:00"
will be submitted. See the Value section above for more details about the supported value types.
<MyDateField label="Birth date" name="birthday" />
<MyDateField label="Birth date" name="birthday" />
<MyDateField
label="Birth date"
name="birthday"
/>
Events#
DateField
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 {useDateFormatter} from 'react-aria';
import {getLocalTimeZone} from '@internationalized/date';
function Example() {
let [date, setDate] = React.useState(parseDate('1985-07-03'));
let formatter = useDateFormatter({ dateStyle: 'full' });
return (
<>
<MyDateField label="Birth date" value={date} onChange={setDate} />
<p>
Selected date:{' '}
{date ? formatter.format(date.toDate(getLocalTimeZone())) : '--'}
</p>
</>
);
}
import {useDateFormatter} from 'react-aria';
import {getLocalTimeZone} from '@internationalized/date';
function Example() {
let [date, setDate] = React.useState(
parseDate('1985-07-03')
);
let formatter = useDateFormatter({ dateStyle: 'full' });
return (
<>
<MyDateField
label="Birth date"
value={date}
onChange={setDate}
/>
<p>
Selected date: {date
? formatter.format(
date.toDate(getLocalTimeZone())
)
: '--'}
</p>
</>
);
}
import {useDateFormatter} from 'react-aria';
import {getLocalTimeZone} from '@internationalized/date';
function Example() {
let [date, setDate] =
React.useState(
parseDate(
'1985-07-03'
)
);
let formatter =
useDateFormatter({
dateStyle: 'full'
});
return (
<>
<MyDateField
label="Birth date"
value={date}
onChange={setDate}
/>
<p>
Selected date:
{' '}
{date
? formatter
.format(
date
.toDate(
getLocalTimeZone()
)
)
: '--'}
</p>
</>
);
}
Validation#
DateField 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 DateField. 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>
<DateField name="date" isRequired> <Label>Appointment date</Label>
<DateInput>
{segment => <DateSegment segment={segment} />}
</DateInput>
<FieldError /> </DateField>
<Button type="submit">Submit</Button>
</Form>
import {
Button,
FieldError,
Form
} from 'react-aria-components';
<Form>
<DateField name="date" isRequired> <Label>Appointment date</Label>
<DateInput>
{(segment) => <DateSegment segment={segment} />}
</DateInput>
<FieldError /> </DateField>
<Button type="submit">Submit</Button>

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 dates after today.
import {today} from '@internationalized/date';
<Form>
<MyDateField
label="Appointment date"
minValue={today(getLocalTimeZone())} defaultValue={parseDate('2022-02-03')} />
<Button type="submit">Submit</Button>
</Form>
import {today} from '@internationalized/date';
<Form>
<MyDateField
label="Appointment date"
minValue={today(getLocalTimeZone())} defaultValue={parseDate('2022-02-03')} />
<Button type="submit">Submit</Button>
</Form>
import {today} from '@internationalized/date';
<Form>
<MyDateField
label="Appointment date"
minValue={today(
getLocalTimeZone()
)} defaultValue={parseDate(
'2022-02-03'
)}
/>
<Button type="submit">
Submit
</Button>
</Form>
Custom validation#
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 date is a weekday and not a weekend according to the current locale.
import {isWeekend} from '@internationalized/date';
import {useLocale} from 'react-aria';
function Example() {
let { locale } = useLocale();
return (
<Form>
<MyDateField
label="Appointment date"
validate={(date) =>
date && isWeekend(date, locale) ? 'We are closed on weekends.' : null} defaultValue={parseDate('2023-10-28')}
/>
<Button type="submit">Submit</Button>
</Form>
);
}
import {isWeekend} from '@internationalized/date';
import {useLocale} from 'react-aria';
function Example() {
let { locale } = useLocale();
return (
<Form>
<MyDateField
label="Appointment date"
validate={(date) =>
date && isWeekend(date, locale)
? 'We are closed on weekends.'
: null} defaultValue={parseDate('2023-10-28')}
/>
<Button type="submit">Submit</Button>
</Form>
);
}
import {isWeekend} from '@internationalized/date';
import {useLocale} from 'react-aria';
function Example() {
let { locale } =
useLocale();

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 the current date at midnight, but you can set it to a more appropriate value if needed.
import {CalendarDate} from '@internationalized/date';
<MyDateField
label="Birth date"
placeholderValue={new CalendarDate(1980, 1, 1)} />
import {CalendarDate} from '@internationalized/date';
<MyDateField
label="Birth date"
placeholderValue={new CalendarDate(1980, 1, 1)} />
import {CalendarDate} from '@internationalized/date';
<MyDateField
label="Birth date"
placeholderValue={new CalendarDate(
1980,
1,
1
)}
/>
Hide time zone#
When a ZonedDateTime
object is provided as the value to DateField
, 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.
<MyDateField
label="Appointment time"
defaultValue={parseZonedDateTime('2022-11-07T10:45[America/Los_Angeles]')}
hideTimeZone />
<MyDateField
label="Appointment time"
defaultValue={parseZonedDateTime(
'2022-11-07T10:45[America/Los_Angeles]'
)}
hideTimeZone
/>
<MyDateField
label="Appointment time"
defaultValue={parseZonedDateTime(
'2022-11-07T10:45[America/Los_Angeles]'
)}
hideTimeZone
/>
Hour cycle#
By default, DateField
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 DateField
to use 24-hour time, regardless of the locale.
<MyDateField
label="Appointment time"
granularity="minute"
hourCycle={24} />
<MyDateField
label="Appointment time"
granularity="minute"
hourCycle={24} />
<MyDateField
label="Appointment time"
granularity="minute"
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-DateField {
/* ... */
}
.react-aria-DateField {
/* ... */
}
.react-aria-DateField {
/* ... */
}
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 DateField
are documented below.
DateField#
A DateField
can be targeted with the .react-aria-DateField
CSS selector, or by overriding with a custom className
. It supports the following states and render props:
Name | CSS Selector | Description |

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 DateField
, 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).
The components in a DateField support the following contexts:
Component | Context | Props | Ref |
DateField | DateFieldContext | DateFieldProps | HTMLDivElement |
This example shows a FieldGroup
component that renders a group of date 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 DateFields are marked invalid and associated with the error message via the aria-describedby
attribute passed to the DateFieldContext
provider.
import {DateFieldContext} 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>
<DateFieldContext.Provider
value={{
isInvalid: !!errorMessage,
'aria-describedby': errorMessage ? errorId : undefined
}}
> {children}
</DateFieldContext.Provider>
{errorMessage && (
<small id={errorId} className="invalid">{errorMessage}</small>
)}
</fieldset>
);
}
<FieldGroup
title="Dates"
errorMessage="Tickets must go on sale before event."
>
<MyDateField label="Event date" defaultValue={parseDate('2023-07-12')} />
<MyDateField
label="Ticket sale date"
defaultValue={parseDate('2023-08-03')}
/>
</FieldGroup>
import {DateFieldContext} 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>
<DateFieldContext.Provider
value={{
isInvalid: !!errorMessage,
'aria-describedby': errorMessage
? errorId
: undefined
}}
> {children}
</DateFieldContext.Provider>
{errorMessage && (
<small id={errorId} className="invalid">
{errorMessage}
</small>
)}
</fieldset>
);
}
<FieldGroup
title="Dates"
errorMessage="Tickets must go on sale before event."
>
<MyDateField
label="Event date"
defaultValue={parseDate('2023-07-12')}
/>
<MyDateField
label="Ticket sale date"
defaultValue={parseDate('2023-08-03')}
/>
</FieldGroup>
import {DateFieldContext} from 'react-aria-components';
import {useId} from 'react-aria';
interface FieldGroupProps {
title?: string;
children?:
React.ReactNode;
errorMessage?: string;
}
function FieldGroup(
{
title,
children,

}: FieldGroupProps
) {
let errorId = useId();
return (

'aria-describedby':
errorMessage

</DateFieldContext.Provider>
{errorMessage && (
<small

)}
/>

Custom children#
DateField 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 DateField.
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 DateField
, in place of the builtin React Aria Components Label
.
<DateField>
<MyCustomLabel>Name</MyCustomLabel> <DateInput>
{segment => <DateSegment segment={segment} />}
</DateInput>
</DateField>
<DateField>
<MyCustomLabel>Name</MyCustomLabel> <DateInput>
{segment => <DateSegment segment={segment} />}
</DateInput>
</DateField>
<DateField>
<MyCustomLabel>
Name
</MyCustomLabel> <DateInput>
{(segment) => (
<DateSegment
segment={segment}
/>
)}
</DateInput>
</DateField>
State#
DateField provides a DateFieldState
object to its children via DateFieldStateContext
. This can be used to access and manipulate the date field's state.
This example shows a DateFormat
component that can be placed within a DateField
to display the expected date format.
import {DateFieldStateContext} from 'react-aria-components';
import {useLocale} from 'react-aria';
function DateFormat() {
let state = React.useContext(DateFieldStateContext)!; let { locale } = useLocale();
let displayNames = new Intl.DisplayNames(locale, { type: 'dateTimeField' });
let format = state.segments.map((segment) =>
segment.type === 'literal' ? segment.text : displayNames.of(segment.type)
).join(' ');
return <small>{format}</small>;
}
<DateField defaultValue={today(getLocalTimeZone())}>
<Label>Date</Label>
<DateInput>
{(segment) => <DateSegment segment={segment} />}
</DateInput>
<DateFormat /></DateField>
import {DateFieldStateContext} from 'react-aria-components';
import {useLocale} from 'react-aria';
function DateFormat() {
let state = React.useContext(DateFieldStateContext)!; let { locale } = useLocale();
let displayNames = new Intl.DisplayNames(locale, {
type: 'dateTimeField'
});
let format = state.segments.map((segment) =>
segment.type === 'literal'
? segment.text
: displayNames.of(segment.type)
).join(' ');
return <small>{format}</small>;
}
<DateField defaultValue={today(getLocalTimeZone())}>
<Label>Date</Label>
<DateInput>
{(segment) => <DateSegment segment={segment} />}
</DateInput>
<DateFormat /></DateField>
import {DateFieldStateContext} from 'react-aria-components';
import {useLocale} from 'react-aria';
function DateFormat() {
let state = React
.useContext(
DateFieldStateContext
)!; let { locale } =
useLocale();
let displayNames =
new Intl
.DisplayNames(
locale,
{
type:
'dateTimeField'
}
);
let format = state
.segments.map(
(segment) =>
segment.type ===
'literal'
? segment.text
: displayNames
.of(
segment
.type
)
).join(' ');
return (
<small>
{format}
</small>
);
}

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. See useDateField for more details.
