Intl.Locale.prototype.getCalendars()

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The getCalendars() method of Intl.Locale instances returns a list of one or more unique calendar identifiers for this locale.

Note: In some versions of some browsers, this method was implemented as an accessor property called calendars. However, because it returns a new array on each access, it is now implemented as a method to prevent the situation of locale.calendars === locale.calendars returning false. Check the browser compatibility table for details.

Syntax

getCalendars()

Parameters

None.

Return value

An array of strings representing all calendars commonly used for the Locale, sorted in descending preference. If the Locale already has a calendar, then the returned array contains that single value.

For a list of supported calendar types, see Intl.supportedValuesOf().

Examples

Obtaining supported calendars

If the Locale object doesn't have a calendar already, getCalendars() lists all commonly-used calendars for the given Locale. For examples of explicitly setting a calendar, see calendar examples.

const arEG = new Intl.Locale("ar-EG");
console.log(arEG.getCalendars()); // ["gregory", "coptic", "islamic", "islamic-civil", "islamic-tbla"]

const jaJP = new Intl.Locale("ja-JP");
console.log(jaJP.getCalendars()); // ["gregory", "japanese"]
