The twelve days of Christmas are a traditional celebration that marks the period between Christmas and Epiphany, the day when the three wise men arrived in Bethlehem to pay tribute to the newborn Jesus. During the twelve days of Christmas, people enjoy holiday activities such as exchanging gifts, attending parties, and spending time with loved ones. The twelve days of Christmas are also associated with the twelve days of celebration in the Nativity story, when Jesus was visited by the shepherds and the wise men.
