Traditionally, Christmas decorations are taken down on January 5th or 6th, but the specific date can vary depending on personal preference and local customs. In many cultures, January 6th is considered the end of the Christmas season, known as "Twelfth Night," and the start of the Epiphany. Taking down decorations on this day is seen as a symbolic gesture of returning to normal life and leaving the holiday season behind. However, there is no set rule for when to take down decorations, and some people may choose to keep them up longer for sentimental reasons.
