Boxing Week
Boxing Week is a period of six days or more that starts with Boxing Day on December 26 and ends with New Year's Eve on December 31. The term was invented by the retail industry around the mid-2000s as an attempt to extend their Boxing Day sales.
Boxing Day is a national holiday in Great Britain. It is the time where British families spend time with each other, if they were not able to bond during Christmas Day. What used to be Boxing Day has evolved into Boxing Week for most stores. It is the biggest week of the year for clothing companies. Since it only has six days, and since some retailers extend their sales beyond that time period, it is not strictly a week. This results in huge lineups at retailers.
