Boxing Day occurs every year on December 26th. If the day after Christmas falls on a Saturday or Sunday, the following Monday is designated as the official public holiday. It was the day when the alms box, collection boxes for the poor often kept in churches, were traditionally opened so that the contents could be distributed to poor people. Some churches still open these boxes on Boxing Day. Get access to all Boxing Day, happy boxing day, boxing day traditions, boxing day uk, boxing day premier league.
