By default, Moment.js comes with English locale strings. If you need other locales, you can load them into Moment.js for later use.

To load a locale, pass the key and the string values to moment.locale.

More details on each of the parts of the locale bundle can be found in the customization section.

Once you load a locale, it becomes the active locale. To change active locales, simply call moment.locale with the key of a loaded locale.

moment.locale('fr');
moment(1316116057189).fromNow() // il y a une heure
moment.locale('en');
moment(1316116057189).fromNow() // an hour ago

As of 2.8.0, changing the global locale doesn't affect existing instances.

moment.locale('fr');
var m = moment(1316116057189);
m.fromNow(); // il y a une heure

moment.locale('en');
m.fromNow(); // il y a une heure
moment(1316116057189).fromNow(); // an hour ago

moment.locale returns the locale used. This is useful because Moment won't change locales if it doesn't know the one you specify.

moment.locale('fr'); // 'fr'
moment.locale('tq'); // 'fr'

You may also specify a list of locales, and Moment will use the first one it has localizations for.

moment.locale(['tq', 'fr']); // 'fr'

Moment will also try locale specifier substrings from most-specific to least-specific until it finds a locale it knows. This is useful when supplying Moment with a locale string pulled from the user's environment, such as window.navigator.language.

moment.locale('en-NZ'); // 'en'

Finally, Moment will search intelligently through an array of locales and their substrings.

moment.locale(['en-NZ', 'en-AU']); // 'en-au', not 'en'
