The spring bank holiday in the United Kingdom has its roots in the 19th century, when workers campaigned for better working conditions and more time off. The Bank Holidays Act of 1871 introduced four bank holidays, including one on the first Monday in August. However, in 1971, the date was changed to the last Monday in August.
In 1965, the UK government introduced the Whitsun bank holiday, which was held on the seventh Monday after Easter. However, this holiday was abolished in 1971 and replaced with the spring bank holiday, which is held on the last Monday in May.
The decision to move the holiday from Whitsun to the end of May was made to create a longer weekend for people to enjoy the warmer weather and participate in outdoor activities. The spring bank holiday has since become a popular time for people to take short breaks and holidays, and for communities to hold festivals and events.
