The 11-day weekend was the name given by the British media to the period of time between Friday, 22 April and 2 May 2011.
As a moveable feast, the bank holidays for Easter (Good Friday and Easter Monday) can occur any day between 20 March and 26 April. Since the early May Day bank holiday was introduced in 1978 it has occasionally fallen on the Monday immediately after Easter Monday. As this was due to happen in 2011 many forward-thinking workers were able to book four days of holiday that in reality meant 11 days off work.
Curiously, there has been an 11-day weekend in the United Kingdom before: in Scotland between 25 December 1999 and 4 January 2000, a period which contained five bank holidays. This event happened at a time of year when it is now accepted that many days' productivity will be lost, whereas the 2011 “weekend” was during the Spring and at a time ofglobal recession. These economic “lost 11 days” echo an actual loss of 11 days that happened in 1752.
It was felt by many that this "11-day weekend", along with the unseasonably hot weather during the period, had detracted attention from and prevented serious debate about the AV referendum and contributed to its defeat.
