This holiday, celebrated on Dec 26, derives from the Old English custom of giving Christmas “boxes” to tradesmen, postmen, and servants. The original boxes were usually made of earthenware and contained money, which could be retrieved only by breaking the boxes open. These days, a gift of money is usually contained in a greeting card and given before the holiday. Where celebrated (Great Britain, Canada, and Australia), Boxing Day is welcomed as a quiet day of recuperation from the season’s hectic festivities. It is also the biggest day of the year for soccer playoffs.
