That's a good question. In most places, Christmas decorations are taken down on January 6th, which is the Feast of the Epiphany. This is also known as Three Kings' Day. The Feast of the Epiphany marks the end of the Christmas season, and it's a time to celebrate the arrival of the wise men to Bethlehem. After January 6th, most people start taking down their decorations and putting them away until next Christmas. However, some people may choose to leave their decorations up for a bit longer, especially if they like the festive atmosphere.
