Change months language

[Costoleta]

Hi guys,

I'm using the pikaday in an app that can be in English or Arabic, is the user who choose it and it can be changed anytime.
I would like to know how can I swipe from one language to another when the user change a language?
It is possible to have something like this?
selectedLanguage = function (IsRTL){
var months;
if(IsRTL){
months = {
previousMonth : 'Previous Month',
nextMonth : 'Next Month',
months :['يناير','فبراير','مارس','إبريل','مايو','يونيو','يوليو','أغسطس','سبتمبر','أكتوبر','نوفمبر','ديسمبر'],
weekdays : ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'],
weekdaysShort : ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'],
midnight : 'Midnight',
noon : 'Noon'
};
}
else {
months = {
previousMonth : 'Previous Month',
nextMonth : 'Next Month',
months : ['January','February','March','April','May','June','July','August','September','October','November','December'],
weekdays : ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'],
weekdaysShort : ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'],
midnight : 'Midnight',
noon : 'Noon'
};
}
return months;
}
