Wiki on Boxing Day
The name derives from the Anglo-Saxon tradition giving seasonal gifts (in the form of a "Christmas box") to less wealthy people and slaves.  In the United Kingdom this was later extended to various workpeople such as labourers, servants, tradespeople and postal workers. 
 Public holiday
Boxing Day is traditionally celebrated on 26 December, St. Stephen's Day, the day after Christmas Day. [ 1 ] [ 2 ] Unlike St. Stephen's Day, Boxing Day is a secular holiday and is not always on 26 December: the public holiday is generally moved to the following Monday if 26 December is a Saturday. If 25 December is a Saturday then both the Monday and Tuesday may be public holidays. However the date of observance of Boxing Day varies between countries.
In Ireland—when it was part of the United Kingdom of Great Britain and Ireland—the UK's Bank Holidays Act 1871 established the feast day of St Stephen as a non-moveable public holiday on 26 December. Since Partition, the name "Boxing Day" is used only by the authorities in Northern Ireland (which remained part of the United Kingdom). Their Boxing Day is a moveable public holiday in line with the rest of the United Kingdom.
The Banking and Financial Dealings Act of 1971 established "Boxing Day" as a public holiday in Scotland. In the Australian state of South Australia, 26 December is a public holiday known as Proclamation Day.
