Boxing Day originated in England in the middle of the nineteenth century under Queen Victoria. December 26th, or Boxing Day is a holiday celebrated in Britain, Australia, New Zealand, Canada, and other Commonwealth countries. It is spent with family and friends at open gatherings with lots of food, fun, friendship and love. Boxing Day is so called because it was the custom on that day for tradesmen to collect their Christmas boxes or gifts in return for good and reliable service throughout the year.
The traditional celebration of Boxing Day included giving money and other gifts to charitable institutions, needy individuals, and people in service jobs.
I would add from myself, December 26th is called "Boxing Day" for the following reason. Lot of shops go on Sale at that date. Some of them give away their itens almost for free. People come to the shopes way before it's open. Once shop is open, they run into the shop and literally start grabbing all they can grab. Sometimes you have to fight the customer, so they start boxing..:) Once I witnessed such "Boxing day" in Future Shop in Canada. Shop was giving away CD and DVD players, some other devices for...1 Dollar! You can imagine that whole shop became a big Boxing Ring.. :)
