Sorta-kinda. I'm Eastern Orthodox and so we don't celebrate Christmas until January 7th, and we don't call it Christmas, although the message is essentially the same. Same with Easter which we call Pascha and which we celebrate on a different day than the West, although every 4 years it occurs on the same day as Western Easter. Due to my family, since they're non-Orthodox, I kind of celebrate both, although the Western holidays hold no religious significance for me.
