Traditionally, Christmas trees are taken down after the holiday season is over, usually on January 6th, which is known as the Epiphany or Three Kings Day. However, the exact date can vary depending on personal or cultural traditions. Some people may choose to keep their Christmas tree up until New Year's Day, while others may take it down as early as Christmas Day. Ultimately, the decision is up to the individual or family. What matters most is that the Christmas tree is a symbol of joy and celebration, and should be enjoyed for as long as possible.
