In time, it was seen that if the most important birth that ever took place could not be celebrated, we should not celebrate any birthday. Besides, neither the Israelites nor the early Christians celebrated birthdays. The Bible mentions only two birthdays, one of Pharaoh and the other of Herod Antipas. Each celebration was marred by an execution. Jehovah’s Witnesses do not celebrate birthdays because these observances have pagan origins and tend to exalt the ones having a birthday.—Genesis 40:20-22; Mark 6:21-28.
