  The last time I checked (something like one year ago), our kernel32 
calendar function were hardcoded for Gregorian Calendar. Thus, to check 
this, you would need native Windows, change the locale to several Asian 
or Arabic ones (in Regional Settings, this shouldn't change the UI 
language) and create a monthcal control. If it still displays a 
Gregorian calendar, then, I think, no implementation is necessary. You 
could also check if there is no monthcal message to choose the calendar 
(locales can support multiple calendars. But AFAIR all support also the 
Gregorian one), but I think I've been checking this once and there 
wasn't (however, I might have been checking the datetime control instead).
