Why don't you just check out the source?

Why do you think you need to know this?

because the calendar in my country is diffrent with GMT calendar, for example in GMT today is 9/21/2011 but in my country today is 6/30/1390. and so in my country DAY_OF_WEEK is diffrent with GMT DAY_OF_WEEK! and I have searched in the Internet about it's source code but there isn't anything!!!!

What country/calendar is that, just out of curiosity?

But the internals of Calendar take care of that stuff for you. If you really want to check it out, the source if freely available. But I think it basically has to do with different locales having different implementations of Calendar (such as GregorianCalendar, BuddhistCalendar, or JapaneseImperialCalendar), which handle things like days of the week and whatnot differently. Or even the same implementation of Calendar taking things like locale and timezone into account for you automatically. The beauty of the class is that you don't really have to worry about it.

I was going to say that looks Islamic, but a quick Google showed that's a lunar calendar and should be around the 1430's.
But I suspect it's related?

Anyway, it is locale dependent. If your locale is included, and the local calendar is included, then you could be in luck. If not, then not.
