DateCalendar is a React component that provides a customizable calendar interface for single date selection.

The component is built with accessibility in mind and follows ARIA best practices for calendar widgets. It provides keyboard navigation, screen reader support, and customizable labels for internationalization.

Usage example

import { DateCalendar } from '@wordpress/components'; function MyComponent() { const [ selected, setSelected ] = useState< Date >( new Date() ); return <DateCalendar selected={ selected } onSelect={ setSelected } />; }

Use custom labels for internationalization. All labels are optional and have sensible defaults:

{ labelNav?: () => string; // Navigation toolbar label labelGrid?: (date: Date) => string; // Month grid label (default: "LLLL y") labelGridcell?: (date: Date, modifiers?: Modifiers) => string; // Grid cell label labelNext?: (month: Date | undefined) => string; // Next month button label labelPrevious?: (month: Date | undefined) => string; // Previous month button label labelDayButton?: (date: Date, modifiers?: Modifiers) => string; // Day button label labelWeekday?: (date: Date) => string; // Weekday label } 

Important: For a correct localized experience, consumers should make sure the locale used for the translated labels and locale prop are consistent.

timeZone

• Type: string
• Required: No

The time zone (IANA or UTC offset) to use in the calendar. See Wikipedia for possible values.

When working with time zones, use the TZDate object exported by this package instead of the native Date object.

import { DateCalendar, TZDate } from '@wordpress/components'; export function WithTimeZone() { const timeZone = 'America/New_York'; const [ selected, setSelected ] = useState< Date | undefined >( new TZDate( 2024, 12, 10, timeZone ) // Use `TZDate` instead of `Date` ); return ( <DateCalendar timeZone={ timeZone } selected={ selected } onSelect={ setSelected } /> ); } 

role

• Type: 'application' | 'dialog' | undefined
• Required: No
• Default: 'application'

The role attribute to add to the container element.

Matcher Types

The calendar component uses a flexible matching system to determine which days should be disabled or have specific modifiers. Here are the available matcher types:

Boolean Matcher

const booleanMatcher: Matcher = true; // Will always match the day 

Date Matcher

const dateMatcher: Matcher = new Date(); // Will match today's date 

Array Matcher

const arrayMatcher: Matcher = [ new Date( 2019, 1, 2 ), new Date( 2019, 1, 4 ), ]; // Will match the days in the array 

Date After Matcher

const afterMatcher: DateAfter = { after: new Date( 2019, 1, 2 ) }; // Will match days after the 2nd of February 2019 

Date Before Matcher

const beforeMatcher: DateBefore = { before: new Date( 2019, 1, 2 ) }; // Will match days before the 2nd of February 2019 

Date Interval Matcher

const intervalMatcher: DateInterval = { after: new Date( 2019, 1, 2 ), before: new Date( 2019, 1, 5 ), }; // Will match the days between the 2nd and the 5th of February 2019 (exclusive) 

Date Range Matcher

const rangeMatcher: DateRange = { from: new Date( 2019, 1, 2 ), to: new Date( 2019, 1, 5 ), }; // Will match the days between the 2nd and the 5th of February 2019 (inclusive) 

Day of Week Matcher

const dayOfWeekMatcher: DayOfWeek = { dayOfWeek: 0 }; // Will match Sundays const weekendMatcher: DayOfWeek = { dayOfWeek: [ 0, 6 ] }; // Will match weekends 

Function Matcher

const functionMatcher: Matcher = ( day: Date ) => { return day.getMonth() === 2; // Will match when month is March };
