why do we celebrate christmas in december 25

Christmas is celebrated on December 25th because it is believed to be the birthday of Jesus Christ, the central figure of Christianity. The date was chosen by the early Church as a way to commemorate his birth and to align with the existing celebrations of the winter solstice and the birth of other deities. The date was eventually standardized throughout the Christian world and has been celebrated annually ever since. It has become a time of joy and generosity, with people coming together to exchange gifts, spend time with family, and remember the birth of Jesus.
