i'm using code create booking system:

http://jsfiddle.net/9zjwdypc/

this example working fine, can't add internalization , others option.

i tried sample code:

$('#dpd1').datepicker({     language: 'it' });  $('#dpd1').datepicker({     format: "dd-mm-yyyy",     weekstart: 1,     language: "fr",     autoclose: true,     todayhighlight: true });  $('#dpd2').datepicker({     format: "dd-mm-yyyy",     weekstart: 1,     language: "fr",     autoclose: true,     todayhighlight: true });  $(window).load(function(){   var nowtemp = new date();   var = new date(nowtemp.getfullyear(), nowtemp.getmonth(), nowtemp.getdate(), 0, 0, 0, 0);    var checkin = $('#dpd1').datepicker({      onrender: function(date) {        return date.valueof() < now.valueof() ? 'disabled' : '';      }   }).on('changedate', function(ev) {      if (ev.date.valueof() > checkout.date.valueof()) {         var newdate = new date(ev.date)         newdate.setdate(newdate.getdate() + 1);         checkout.setvalue(newdate);      }      checkin.hide();      $('#dpd2')[0].focus();   }).data('datepicker');   var checkout = $('#dpd2').datepicker({      onrender: function(date) {         return date.valueof() <= checkin.date.valueof() ? 'disabled' : '';      }   }).on('changedate', function(ev) {      checkout.hide();   }).data('datepicker'); }); 

adding:

<script src="http://eternicode.github.io/bootstrap-datepicker/bootstrap-datepicker/js/locales/bootstrap-datepicker.fr.js"></script> 

the same using this:

$(document).ready(function(){     $.fn.datepicker.defaults.language = 'it'; });    

this error: typeerror: $.fn.datepicker.dates undefined

you have include french language file , try use italian language...
