Charities including Foundation4Peace, Global Action Plan, Jumble Aid, the National Autistic Society and World Vision are throwing their weight behind the campaign.
The campaign will ask the estimated three million people who will be on holiday on the five days of 'Twixtmas' ( 27 – 31 December) to use the time to perform small tasks for social good. It hopes to make 'Twixtmas' a recognised festive holiday.
Examples given include giving to a charity, unplugging your mobile charger, allowing someone you care about to speak to you for five minutes uninterrupted, or helping a neighbour.
More leftfield examples include being kind to an animal and 'go hug a tree'.
The campaign has been masterminded by not-for-profit organisation Flexible Thinking Forum and its agency Green Communications.
