CAFOD Family Fast Day is on Friday 23 February.
Over the past sixty years this has become part of Lent for many.
The idea is to give up the day’s main meal, by just having maybe soup, and send the cost to CAFOD.
CAFOD is the Catholic Agency for Overseas Development working alongside Christian Aid.
This year’s appeal will be going towards the funding of a three-year project to improve nutrition in Zimbabwe.
All money donated in Britain will be doubled by HM Government. So a £5 lunch can, with match funding and gift aid, raise £11.25.
A family deciding that lunch cots £24 will see their donation turn into £54.
