Traditionally, Christmas decorations are taken down after the holiday season, usually on or around the twelfth day of Christmas, which is January 5th. This practice is known as Epiphany or the Feast of the Three Kings, and is believed to be the day when the three wise men visited the baby Jesus. Many people choose to leave their decorations up until New Year's Eve, while others prefer to take them down right away. Ultimately, it's up to each individual to decide when they feel is the right time to pack up their holiday cheer.
