Boxing Day is a secular holiday that is traditionally celebrated on 26 December, 2023, the day after Christmas Day, when servants and tradespeople would receive gifts from their superiors or employers, known as a "Christmas box". However, when 26 December falls on a Sunday, Boxing Day in many places is moved to 27 December.
Today, Boxing Day is better known as a bank or public holiday that occurs on 26 December, or the first or second weekday after Christmas Day, depending on national or regional laws. Boxing Day is observed in the United Kingdom, Hong Kong, Australia, Canada, New Zealand, and some other Commonwealth nations. In South Africa, Boxing Day was renamed to Day of Goodwill in 1994. In Ireland it is recognized as St. Stephen's Day or the Day of the Wren.
In Britain, Canada, New Zealand and some states of Australia, Boxing Day is primarily known as a shopping holiday, much like the day after Thanksgiving in the United States. It is a time where shops have sales, often with dramatic price reductions. For many merchants, Boxing Day has become the day of the year with the greatest revenue. Many retailers open very early (typically 5 am or even earlier) and offer doorbuster deals and loss leaders to draw people to their stores.
In some European countries, notably Germany, Poland, Lithuania, Scandinavia, and the Netherlands, 26 December is celebrated as the Second Christmas Day. In Canada, Boxing Day takes place on 26 December and is a federal public holiday. In Ontario, Boxing Day is a statutory holiday where all full-time workers receive time off with pay.
