NlsCalendar supports multi language (internationalization). Language file is located in lib/lang/ folder. To create new translation, just copy the nlscalendar_i18n_en.js and rename it. Then translates all the words in the file. To use the translation with calendar, just include the file in your page for example:

        
        //include the langauge file, this must come first before nlscalendar.js
        <script src="lib/lang/nlscalendar_i18n_de.js" langauge="Javascript"></script>

        <script src="lib/nlscalendar.js" language="Javascript"></script>
