It's generally considered appropriate to take down the Christmas tree no later than January 6th, also known as the Feast of the Epiphany. This is a Christian holiday that marks the end of the Christmas season, and many families choose to take down their decorations on or before this date. However, it's ultimately up to you and your family to decide when to take down the tree. Some people prefer to leave it up longer, while others prefer to take it down sooner.
