Christmas is an annual holiday celebrated by the Christians, on 25th December, in the major part of the world, to celebrate the Nativity of Jesus Christ. Christians believe that Jesus is the son of God, the Messiah sent from Heaven to save the world.
It is believed that Jesus was born to Mary in Bethlehem around two thousand years ago. Jesus was born in a manger because there was no room for him and for his parents, Mary and Joseph. The word Christmas comes from Cristes maesse, an early English phrase that means Mass of Christ.
