Christmas Jumper Day is an annual fundraising campaign in the UK in aid of Save the Children. On a specific Friday in December, Save the Children encourages people to make the world better with a sweater and raise funds for the charity by wearing a Christmas jumper and making a minimum donation of £1.
Those taking part can wear a Christmas jumper they already own, decorate an existing jumper with festive decorations, or even knit their own. Groups may take part in additional fundraising activities on the day. Save the Children launched Christmas Jumper Day in 2012 on Friday, 14 December. In 2013, Christmas Jumper Day took place on Friday, 13 December.
