Christmas officially ends on January 6th, which is the Feast of the Epiphany. It is also known as Three Kings' Day or Twelfth Night. This day celebrates the arrival of the Three Wise Men to visit baby Jesus and is traditionally marked by the sharing of a special cake called the galette des rois (King's Cake) in many parts of the world. After January 6th, the celebration of Christmas is considered to have come to an end.
