Christmas is celebrated on December 25th to commemorate the birth of Jesus Christ. The Christmas season begins on this day and lasts until the second Sunday in January. Key events and symbols of the season include the Nativity scene, readings from the gospels of Matthew and Luke describing Jesus' birth, and religious feasts honoring Jesus, his family, and early Christian figures like Saint Stephen and Saint John. The liturgical color of the season is white to represent joy, glory, and innocence.
