Yes, Christmas is celebrated as the birthday of Jesus Christ, the central figure in Christianity. The date of his birth is not mentioned in the Bible, but the early Christians observed it on December 25th, and over time, the holiday came to be associated with the winter solstice and the celebration of light, hope, and the birth of a messiah. So, while Christmas is not Jesus' actual birthday, it has become a special day of remembrance and celebration for Christians around the world.
