Hi Hooman, The Hijri calendar introduced in MSDN does not give you a totally accurate date, since as you know there are many many elements and dependancies around finding a correct Hijri date. It also does not work based on a specific region. It simply lets you adjust it manually by 2 days. It means it has always a probability of 1 or 2 days of error and seems that they prefer this descripency in return of the other advantages it gives: to cover every variant and every region, and the ability to fix the calendar in case that the observations change the authoritative estimated version of the calendar at any time. It is possible to implement the Hijri calendar the way ODC suggested, using online tables of Hijri adjustments for the past years but it still limits the divices to be online and yet it's impossible again to find assured correct dates in the future. With the current conditions in mind I think it is not out of sence to choose this particular calendar for the OS to be ordinarily useable rather than tailoring it for complex calendarical conversions.
