By default, Moment.js comes with English (United States) 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 .

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

    1. moment.locale('fr', {

    47.     // this function (look at locale/id.js for an example).

    55.         dow : 1, // Monday is the first day of the week.
    56.         doy : 4  // Used to determine first week of the year.
    57.     }
    58. });

    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.

    As of 2.21.0, Moment will console.warn if the locale is unavailable.

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

    1. moment.locale('fr');
    2. var m = moment(1316116057189);
    3. m.fromNow(); // il y a une heure
    5. moment.locale('en');
    6. m.fromNow(); // il y a une heure
    7. moment(1316116057189).fromNow(); // an hour ago

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

    1. 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.

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