The holiday Boxing Day may get it's name from the 19th century English custom of giving Christmas boxes containing food or money to family servants and suppliers, the day after Christmas.
Another possibility is Boxing Day may have come from the opening of church poor boxes that day.
The most basic understanding is that gifts, or boxes, were given to those who were less fortunate, on the day after Christmas, while gifts to those with equal standing were given on Christmas day.
It is also known as, the Feast of St. Stephen, or St. Stephen's Day - the first Christian martyr.
It is most often celebrated in Australia, Britain, New Zealand, and Canada on December 26.
Although it is a statutory holiday in these countries it is not celebrated as such. Most countries host Boxing Day sales on that day which have little or nothing to do with the holiday at all.
