The twelve days of Christmas typically start on December 25th, Christmas Day, and end on January 6th, the Feast of Epiphany, also known as Three Kings' Day. It's a period of time when Christians around the world celebrate the birth of Jesus and reflect on the gift of faith and salvation. During this time, it's traditional for many people to exchange gifts and sing Christmas carols, reflecting on the joys of the season and looking forward to the new year ahead.
