Persian Calender for MSP

Hello

In MSP 2010 in addition of Gregorian Calender there are two  Calender: Hijri and Thai.

Now I want to add Persian Calendar (Calender of my region) to MSP Calendars. Do you have any experience in this field? I know algorithms for programming Persian calender or changing other calendars to Persian but I want to know how to add Persian calendar and with what format.

there are some companies that changed hijri calender to Persian and when you open option in MSP you will see Persian calender instead of hijri calender. i want to know how they did this.

I know there is class for persian calender  in .net framework
