Is there a timeline to take down your holiday decorations? But if you’d like to extend the holiday season, I’ve got good news. If your home is the last one on the block still rocking the holiday lights, chances are someone has told you it’s 2021 and you can take them down already. Dating back to the fourth century, many Christians mark the end of the Christmas season on the Twelfth Night, also known as the Eve of the Epiphany. Tradition dictates that the Twelfth Night is the best time to take down your festive decorations as it’s believed that waiting too long after the Twelfth Night will bring bad luck.
