nowaday there is so many persian users for OTRS, but there is n o Persian ( Hijri Shamsi ) calendar out there,
I am asking for a Persian Calendar Module or sugessting to provide this calendar with JQuery,
I do not know that is it possible for OTRS to use from jquery to adding persian calendar or not, but I have found a Persian Calendar with JQuery that may help
you can find it http://hasheminezhad.com/datepicker with some sample ( and description in farsi )
usage of this calendar is so simple , all you need is that adding 2 javascript class (ui.datepicker-cc.js & ui.datepicker-cc-fa.js) in a page with other Jquery Library ( jquery.js & ui.core.js ) and use it.
you can download it at http://hasheminezhad.com/sites/default/files/hasheminezhad.com/datepicker-cc2.zip
and many many thanks from Mahdi hashemi Nezhad for providing this usefull library.
