why do we celebrate christmas on dec 25

Christmas is celebrated on December 25th to commemorate the birth of Jesus Christ. According to Christian tradition, Jesus was born in Bethlehem to the Virgin Mary and her husband Joseph. The day was originally celebrated in the Eastern Church as the Feast of the Nativity, but later became known as Christmas in the Western Church. The date was likely chosen to coincide with the winter solstice, which was already a time of celebration in many cultures. Today, Christmas has become a global holiday that celebrates the spirit of love, generosity, and goodwill towards others.
