Well, there are a few schools of thought on when to take down the Christmas tree. Some people believe that it should be taken down on January 1st, as a way to symbolically welcome in the new year. Others argue that it should be left up until the Epiphany, or Three Kings Day, which is on January 6th, as a way to commemorate the arrival of the wise men in Bethlehem. Still, others say that it's just a matter of personal preference, and that you can take it down whenever you want to!
