Changing locale globally

By default, Day.js comes with English locale only.

If you need other locales, you can load them on demand.

require('dayjs/locale/de');

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

Changing the global locale doesn't affect existing instances.

dayjs.locale('de'); // use loaded locale globally
dayjs.locale('en'); // switch back to default English locale globally
