When I was a little kid, I thought Boxing Day had something to do with special prize-fights and wondered how that squared with the Christmas spirit. Boxing Day, celebrated on December 26 in the U.K. and some other countries, stems from the practice whereby the wealthy would give their servants boxes of goodies (perhaps leftovers or unwanted gifts ;)?). It developed into a public holiday. Like other dated holidays, it is adjusted if it falls on a Saturday or a Sunday. Boxing Day is usually celebrated by shopping and stores have Boxing Day sales and even Boxing Week sales, much like Black Friday (the day after Thanksgiving) in the U.S. Sports do play a part, with special football (soccer) and rugby matches sheduled for Boxing Day.
