The clocks will go back at 2am on Sunday, October 26, marking the official start of Greenwich Mean Time.
This means an extra hour in bed for most people, and potentially longer opening times for late-night bars and clubs should they choose to stay open.
Most smartphones and digital devices will update automatically, but analogue clocks and other digital clocks such as those in cars and ovens will need to be changed manually.
The tradition of changing the clocks began more than 100 years ago when parliament passed the Summer Time Act in 1916, creating British Summer Time.
The system was designed to stop people wasting valuable hours of light during summer months and to save fuel during the First World War.
The campaign was started in 1907 by William Willett, and Germany became the first country to adopt the clock-changing system in April 1916, with the UK following in May that year.
Despite the public remaining divided on whether the tradition should continue, all attempts to scrap the system in the UK have failed.
While Daylight Saving Time is observed in most of Europe, North America and Australasia, most places in Africa and Asia do not follow the practice.
The clocks will go forward again on March 29, 2026, marking the start of British Summer Time.
Until then, evenings will become progressively darker until the winter solstice. So brace yourselves!
