It’s that time of year again when the clocks go back for winter, gifting people across the UK an extra hour in bed. Hoorah!
When do the clocks go back?
This year the clocks will change at 2am on Sunday 29 October, going back by one hour, putting the UK back on Greenwich Mean Time (GMT).
Why do the clocks go back?
Changing the clocks began over 100 years ago after the government passed the Summer Time Act in 1916. This happened during the First World War.
It followed years of campaigning by builder William Willett who published a leaflet called “The Waste of Daylight”. Willet argued that moving the clocks back in the summer would save on energy costs. He added that it would give people longer to enjoy outdoors.
He was also a keen golfer and disliked the effect that sun-down had on his games in the summer by cutting them short.
Daylight saving time was eventually introduced by the government the year after Willett died. It was done in a bid to save fuel during the war.
When will the clocks go forward again?
The clocks will go forward by an hour on Sunday 25 March 2018. This will be when the UK reverts again to British Summer Time (BST). There will be less light in the mornings then, and more in the evenings.
Where else uses Daylight Saving Time (DST)?
Much of the world does not use DST. 65% of countries do not use this method. This means 80% of the world’s population does not change its clocks, according to the BBC.
Most countries in Europe use it apart from Belarus, Iceland, Georgia and Armenia. The whole of the United States employs DST apart from Hawaii and part of Arizona.
