Christmas, also known as Christmas Day, is translated as "Christ's Mass". It originated from the Roman Festival of Saturnalia, which was celebration of the New Year, and had no connection with Christianity. After the Christian Church became popular in the Roman Empire, the Church followed the trend and incorporated this folk festival into Christian system, while celebrating the birth of Jesus. However, Christmas is not the actual birthday of Jesus, because the Bible does not record the specific day of Jesus' birth, nor it mention such a festival. This is the result of Christianity absorbing ancient Roman mythology.
