One Day at Christmas is a charity event organised by the UK events industry creating a wonderful Christmas day experience for people who are alone or isolated.
Originally started by Mash Media in 2017 at London’s Excel London, the event has gathered huge momentum each year. We are delighted to welcome three new venues in 2025 (P&J Live Aberdeen and Tobacco Dock London) which means the event will now be hosted simultaneously across 10 UK venues on Friday 5 December 2025.
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.
