If you’ve been looking for a reason to keep your Christmas decorations up a bit longer, this is it.

When it comes to holiday decorations, there are two kinds of people: Those who take down their Christmas trees on December 26, and those who aren’t quite ready for the season to be over. And while taking down the tree is usually less fun than putting it up, there’s actually another good reason many people wait to do it. So, if you’ve been looking for an excuse to keep listening to Christmas music and admiring your festive decor, you’re in luck: Tradition says you should be celebrating Christmas (and leaving your decorated tree up) through January 6.

You’re probably familiar with the song about the 12 days of Christmas—but you may not have known that the 12 days don’t actually start until Christmas Day, meaning there are almost two full weeks of celebrating to do after Santa arrives. According to Christian tradition, January 6 marks the day the three kings actually arrived in Bethlehem and signals the end of the Christmas celebrations.

This day is called The Feast of Epiphany, The Twelfth Night, or Three Kings Day, and in some parts of the world, it signifies a celebration that’s just as big as the one on Christmas Day. And while we’ll welcome any excuse to leave the red and gold ornaments ($5, Target) and multicolor strand lights ($8, Target) up a little longer, tradition says it’s actually unlucky to take your tree down before this date. Now you know how long to leave the Christmas treeup. When you finally take down the tree, don’t just leave it on the curb; you can actually recycle live Christmas trees by finding a recycling program or having them chipped into mulch for your garden.

While the Christmas festivities technically end on Epiphany, the holidays aren’t over just yet. The day also marks the official start of the Mardi Gras season, so it’s tradition to serve King Cake on January 6. The tradition of Three Kings Day is actually where the name “king cake” comes from—and why there’s a tiny plastic baby hidden inside.
