please help me how to change default calendar format to Hijri Date?

without almost a complete rewrite of calendar.php and associated functions, it can't be done. Plus it would be dependent on the country/culture you are trying to base the first day of the month on.

There are a few published functions for converting Gregorian/Julian to Hijri but I am not sure what how they are handling the first day.
