Thread:Project:Support desk/calendar type/reply

All extensions which allow you to add a calendar to your wiki are collected in Category:Calendar extensions, but I don't know if any of them support Jalali calendars. If you have a Google account or if you can get one, you might be able to do it by adding http://code.google.com/p/jalali-gcal (a script) to your Google calendar. If that works, you can choose from a number of extensions that allow you to embed a Google calendar within your wiki (see Category:Calendar extensions).

Hope that helps.
