when is christmas jumper day 2025

Christmas Jumper Day 2025 is on Thursday 11 December 2025 in the UK, as set by Save the Children for their official fundraising event.

Key date for your diary

• Official Save the Children Christmas Jumper Day 2025 : Thursday 11 December 2025.

• Many schools and workplaces still choose a nearby day (often the Friday) if that suits them better, and Save the Children explicitly says you can celebrate on another day if 11 December does not work.

Why the date matters

• Christmas Jumper Day is a big charity fundraiser, especially across UK schools, offices and community groups, raising money for children through Save the Children.

• Joining in on the official day means you are part of the wider national push, with millions of people wearing festive jumpers at the same time.

Quick planning tips

• Mark Thursday 11 December 2025 in your calendar and start planning jumper themes, office or school photos, and donation links.

• If your group cannot do the Thursday, pick a nearby date and still treat it as your own “Christmas Jumper Day” fundraiser; Save the Children encourages this flexible approach.
