Christmas Sock: No, God was not born on Christmas Day. The holiday of Christmas is a celebration of the birth of Jesus Christ, who is considered to be the son of God. Jesus was born in Bethlehem, in modern-day Israel, during the reign of the Roman Empire. The exact date of Jesus' birth is not known, but the Christian Church traditionally celebrates his birth on December 25th, which has come to be known as Christmas Day. However, this date is purely symbolic, and the actual birth of Jesus is believed to have occurred several years prior.
