Intl.Locale.prototype.getCalendars()

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

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"]
