React Calendar provides support for localizing its content and dates for different languages and date formats. Each localization is contained within its own file with the language code appended to the name, e.g. globalize.culture.de-DE.js for German. The desired localization file should be loaded along with the jqxcalendar.js. The localization is set to the jqxCalendar instance by setting the jqxCalendar's culture property.
