How do bosnians celebrate Christmas?

most bosnians are of the Muslim religion and Muslims have their own holidays so they dont celebrate Christmas.

December 25th 2011 UPDATE:

Actually to correct the above answer since its partially untrue. Bosnians can celebrate Christmas because some ARE Christians. Most are Orthodox which just celebrate Christmas on or near January 7 in the Gregorian calendar, which is celebrated around the same time on the Julian calendar (what Canadians and American's use). Very minimal are Muslim but as any religion it could pick up at any given time, and yes if they are Muslim they do not celebrate Christmas. Most are Orthodox though because they are Slavic like the Greeks, Russians, Ukrainians, etc. It all depends also on how devout they are as well, some just celebrate on both of just December 25th because its become "tradition" in the Western World.
