One thing is sure that Jesus no longer exist on Christmas day even though it is claimed to be the birthday of Jesus. In fact, Christmas isn’t the birthday of Jesus but a Roman traditional holiday just like the Easter. Those days didn’t even exist in early period of Jesus believers in Israel but later proclaimed to be Christian days by Romans simply replacing their own traditional holidays.
The birthday of Jesus must be calculated on the Jewish calendar (lunar), not on Gregorian Roman calendar (solar). Anyway, Christmas today is the day of Santa Claus who successfully (?) replaced the position of Jesus. The Messiah is dead but the Shopping God took his place. People spend a lot of money just to make the season funnier. Of course, Christmas is the biggest day for merchants which gives them 30 times bigger sale on one single day.
