Christmas Jumper Day is: Thursday, 10 December 2026
When is Christmas Jumper Day 2026?
This year Christmas Jumper Day lands on Thursday, 10 December 2026. It's always the second Thursday of December, so it slots in nicely just as the countdown to Christmas really gets going. Unlike Christmas Day, which never budges from 25 December, this one shifts about a little each year, which is exactly why it's worth checking in good time.
The reason is simple: the day is tied to a weekday rather than a fixed date. Because it follows the second Thursday of December, the actual date moves around depending on how the calendar falls. The rule itself stays put, though, so if you ever lose track, just count to the second Thursday of the month and you've found it.
What is Christmas Jumper Day?
Christmas Jumper Day is run by Save the Children, and the idea couldn't be friendlier. You pull on a festive jumper, make a small donation, and that money goes towards helping children both here in the UK and around the world. It's a bit of seasonal fun with a genuinely good cause underneath it.
What started as a modest idea has grown into one of the most cheerful days on the December calendar. Schools, offices and homes up and down the country join in every year, and all those small donations add up to a serious amount of support for children who need it. So while it looks like a bit of festive silliness, there's real warmth behind every jumper.
How to take part
Joining in is wonderfully easy. At work, someone usually rallies the team, everyone turns up in their best festive knitwear, and a small donation goes into the pot. Schools often do much the same, with children wearing jumpers instead of uniform for the day in exchange for a contribution. And if you're at home, there's nothing stopping you from popping one on anyway and donating online.
Save the Children make donating straightforward, whether you give as an individual or pool it together as a group. Half the fun is in the taking part, so feel free to add a bit of friendly competition, a prize for the most outrageous design, or a festive bake to go alongside. The point isn't to spend a fortune. It's to have a laugh, wear something daft and do a bit of good while you're at it.
Choosing your Christmas jumper
With the date sorted, the only thing left is the fun part: picking the jumper. Some people love a classic Fair Isle look with snowflakes and reindeer, while others go straight for the gloriously silly, the louder and dafter the better. Both are entirely in the spirit of the day, so there's no wrong answer here.
If you're after something timeless, our Christmas Jumpers have plenty to choose from, and there's a good selection of Ugly Christmas Jumpers for anyone who wants to raise a few eyebrows in the office. Getting the whole household involved? Matching Family Christmas Jumpers are a sure way to win the day at the school gates.
Whatever you choose, the main thing is to order in plenty of time so your jumper arrives before the big day. Now you know when Christmas Jumper Day is and how many days you've got left to plan, all that remains is to find a jumper you'll be glad to be seen in, and do a little good while wearing it.
