# Languages (locale) Country-specific app internationalisation. This is not an app, but instead it is a library that can be used by other applications or widgets to display messages. ## Usage Some menus that pop up are translated automatically, but if you're writing an application you can use the `locale` library to do all the translation for you. See https://www.espruino.com/Bangle.js+Locale for full examples. ```JS // Date to date string (long) >require('locale').date(new Date()) ="Donnerstag, 02. April 2020" // Date to date string (short) >require('locale').date(new Date(),1) ="02.04.2020" ``` Bangle.js has a `locale` library built in that is just a standard British English (`en_GB`) localisation - so you can use `locale` in your apps without requiring users to have this Language library installed.
