When Do the Clocks Change?
Clocks across the United Kingdom will spring forward by one hour at 1:00 am on Sunday, 29 March 2026, marking the official start of British Summer Time. At 1:00 am, clocks will automatically jump to 2:00 am, meaning that people will lose one hour of sleep but gain an extra hour of evening daylight.
The clock change affects every aspect of daily life, from when the sun rises and sets to transportation schedules and digital device updates. Most modern smartphones, computers, and smart devices will update automatically, but analogue clocks, ovens, and car dashboards will need to be manually adjusted.
Why Do We Change the Clocks?
The tradition of changing clocks dates back to the Summer Time Act of 1916, introduced during the First World War to make better use of natural daylight and conserve energy. More than a century later, the practice continues despite periodic debates about whether it remains necessary or beneficial in the modern era.
The European Parliament voted to abolish seasonal clock changes in 2019, but implementation has been repeatedly delayed and the United Kingdom, no longer an EU member, is not bound by any future European decision on the matter. Periodic surveys of the British public have shown mixed opinions on the subject.
Health and Safety Tips
Sleep experts recommend gradually adjusting bedtimes in the days leading up to the clock change to minimise the impact on circadian rhythms. Studies have shown that the spring clock change is associated with a temporary increase in road accidents and workplace injuries as people adjust to the lost hour. Motorists are particularly advised to be extra vigilant on Monday morning when the effects of disrupted sleep patterns are most pronounced.
