Typically, Christmas decorations are kept up until January 5th or 6th, which is known as the Epiphany. This marks the end of the Christmas season and is the traditional date for taking down decorations. Some people may choose to keep their decorations up for a few days or weeks longer, depending on their personal preferences. It's also common to see some homes with Christmas lights or decorations that remain up throughout the winter season. Ultimately, the decision of when to take down decorations is up to the individual and depends on their personal beliefs and customs.
