As part of the campaign, artist Cat Ingall has created a message board packed with post-it notes suggesting kind acts such as speaking to an elderly neighbour or holding the door open for someone.
The board has been set up at Glasgow’s Buchanan Street subway station where commuters and passers-by are being asked to take a post-it and carry out the task written on it.
Minister for Europe, Migration and International Development Ben Macpherson helped start the campaign by handing out the POST-ITS.
Mr Macpherson said: “St Andrew’s Day is a perfect opportunity for everyone in Scotland to celebrate our national day in an inclusive, compassionate, internationalist spirit, and to affirm the shared values that unite us.
“I would encourage everyone to carry out #onekindact this St Andrew’s Day, by either attending one of the many events taking place across the country or by engaging in an act of kindness of their own.
“Coming together to do one kind act to make someone’s day showcases our kindness, inclusivity and compassionate spirit to the world.”
The message board of kindness marks the start of Scotland's Winter Festivals. Supported with £400,000 from the Scottish Government, the Festivals’ programme encourages communities to come together in celebration of Scotland’s national days, including Hogmanay and Burns Night.
The Scottish Government has also teamed up with The Fair Saturday Foundation for a second year with a programme of more than 100 nationwide events set to raise valuable funds for deserving social causes. Fair Saturday invites people to enjoy the arts and culture and contribute to positive social change as an antidote to the consumerism of Black Friday.
