You can put up your Christmas tree anytime that feels right for you, with common guidance leaning toward late November to early December. Here are practical touchpoints to consider:

• Traditional timing
  • Many people start decorating with a tree on the first day of Advent or in early December, aligning with the start of the Christmas countdown. If you’re following Advent-based tradition, Advent begins on the fourth Sunday before Christmas, which shifts each year. This year that places the earliest traditional start in late November to early December, depending on when Advent starts.

• Real-tree freshness
  • If you’re using a real tree, put it up in the first week of December or as soon as you’re comfortable, so it stays fresh through the season. Real trees typically last about four weeks with proper care.

• Personal preference
  • Some households prefer to start after Thanksgiving weekend in the U.S. or on the first weekend of December, while others enjoy decorating as soon as Halloween is over. There’s no right or wrong answer beyond what brings you the most joy.

• Practical tips
  • Consider how long you want to enjoy the decorations: if you want a longer festive window, you might set up in early December; if you enjoy Christmas ambiance earlier, late November can work. Also factor whether you’ll be away during peak times.

Bottom line: there’s no universal rule—set up your tree when it feels festive for you, commonly from late November to early December, with Advent timing offering a traditional anchor if you follow that calendar.
