Next weekend, the clocks will 'spring forward', marking the start of longer and brighter evenings as we approach summer.

After what has seemed like an extended winter for many, millions of people are likely looking forward to the additional daylight hours.

Across the UK, clocks will advance by one hour at 1am on Sunday, March 29, a day earlier than in 2025, signifying the official start of British Summer Time (BST). They will then revert to standard time on the last Sunday in October.

Immediately after the clock change, certain regions of the UK will witness sunsets after 8pm, including County Fermanagh in Northern Ireland.

For London, however, it will take roughly another 19 days, until April 17, before a post-8pm sunset occurs.

In Edinburgh, the first sunset after 8pm is expected to occur around April 6, April 10 for Cardiff, and approximately April 12 for Birmingham, according to predictions.

Why do the clocks 'spring forward' in March?

The custom of initiating BST by advancing the clocks in spring was first established in 1916.

The original concept of maximising daylight hours was initially proposed by American inventor Benjamin Franklin in 1784 and subsequently explored in a pamphlet titled "The Waste of Daylight" by British writer William Willett in 1907.

In 1916, a year after Willett's death, Germany became the first country to implement daylight saving time.

The UK quickly followed suit, along with numerous other nations involved in the First World War (1914-1918), according to the Royal Museums Greenwich.
