One Day at Christmas is a charity event organised by the UK events industry, creating a wonderful Christmas Day experience for 3,500 people who are alone or isolated.
Originally started by Mash Media in 2015 at Excel London, the event has gathered huge momentum each year. In 2026, we are delighted to have 9 venues hosting simultaneously across the UK, taking place on Friday 4 December 2026
Last year, over 70 organisations from the UK events industry supported One Day at Christmas with sponsorship, gifts, entertainment and their time, helping to make a magical day for all.
