[Pharo-users] How To Implement A New Calendar

Hi all, In Iran we use a calendar different from Gergorian and Islamic calendars; it's called Jalali calendar[1]. The people in Afghanistan use the same calendar but with different month names. So, I was wondering how can I implement this calendar in Pharo? I've already done the conversion routines in Python[2] but that is nowhere near a real calendar. What I have in mind is a subclass (?) of `Date` which seamlessly supports all `Date` operations but using a different calendar system. I'd appreciate any hits/pointers.
