How do I localize the jQuery UI Datepicker?

For those that still have problems, you have to download the language file your want from here:

https://github.com/jquery/jquery-ui/tree/master/ui/i18n

and then include it in your page like this for example(italian language):

<script type="text/javascript" src="/scripts/jquery.ui.datepicker-it.js"></script>

then use zilverdistel's code :D

I figured out the demo and implemented it the following way:

$.datepicker.setDefaults(  $.extend(    {'dateFormat':'dd-mm-yy'},    $.datepicker.regional['nl']  ));

I needed to set the default for the dateformat too ...

The string $.datepicker.regional['it'] not translate all words.

For translate the datepicker you must specify some variables:

$.datepicker.regional['it'] = {    closeText: 'Chiudi', // set a close button text    currentText: 'Oggi', // set today text    monthNames: ['Gennaio','Febbraio','Marzo','Aprile','Maggio','Giugno',   'Luglio','Agosto','Settembre','Ottobre','Novembre','Dicembre'], // set month names    monthNamesShort: ['Gen','Feb','Mar','Apr','Mag','Giu','Lug','Ago','Set','Ott','Nov','Dic'], // set short month names    dayNames: ['Domenica','Luned&#236','Marted&#236','Mercoled&#236','Gioved&#236','Venerd&#236','Sabato'], // set days names    dayNamesShort: ['Dom','Lun','Mar','Mer','Gio','Ven','Sab'], // set short day names    dayNamesMin: ['Do','Lu','Ma','Me','Gio','Ve','Sa'], // set more short days names    dateFormat: 'dd/mm/yy' // set format date};$.datepicker.setDefaults($.datepicker.regional['it']);$(".datepicker").datepicker();

In this case your datepicker is properly translated.
