The Christmas tree should be taken down after the holiday season, typically by January 6th, which is known as the Feast of Epiphany. Taking the tree down too early can feel like a reminder that the joyous season is over, while leaving it up too long can cause the tree to become dry and brittle, creating a fire hazard. Therefore, it is best to enjoy the tree for as long as possible but to also be mindful of its safety and the passing of the holiday season.
