Hi!
Christmas Day falls on December 25. It is preceded by Christmas Eve on December 24, and in some countries is followed by Boxing Day on December 26. Some Eastern Orthodox Churches celebrate Christmas on January 7, which corresponds to December 25 on the Julian calendar. December 25 as a birthdate for Jesus is merely traditional, and is not thought to be his actual date of birth.Good luck!

Ha ! you just copy/pasted a paragraph from Wikipedia :P
