The question of when to take down a Christmas tree is a controversial one. Some people believe that it should be taken down on the first day of the year, while others argue that it should remain until the end of January. However, many experts advise that the best time to take down the tree is before January 7th, which is the day of Epiphany. Taking down the tree before this date is important because it symbolizes the end of the Christmas season and the beginning of a new year. Taking down the tree after January 7th is not recommended because it could cause bad luck.
