"Keeping your Christmas tree up beyond the holiday season can be considered bad luck by some people. The tradition of taking down the tree and decorations after Christmas Day is believed to be a way to ensure good luck for the coming year. However, this tradition is not universally followed, and many people choose to keep their trees up longer for sentimental reasons or simply because they enjoy the festive atmosphere. Ultimately, whether or not you take down your tree is a personal decision, and there are no hard and fast rules about what is considered good or bad luck in this regard."
