It is NOT a stupid question.\n\nThe ONLY celebration which Jesus commanded his followers to keep is the yearly memorial of his death, which happens after sundown on the date corresponding to the 14th day of Nisan on the Jewish calendar.  This year it will be on April 12th.\n\nSee Luke 22:19 - "Also, he (Jesus) took a loaf, gave thanks, broke it, and gave it to them, saying: “This means my body which is to be given in your behalf. KEEP DOING THIS IN REMEMBRANCE OF ME."
