As the countdown to spring intensifies, Britons across the nation are eagerly anticipating the end of gloomy mornings and evenings, with milder weather and longer daylight hours on the horizon. The most significant shift occurs when the clocks spring forward, transitioning from Greenwich Mean Time (GMT) to British Summer Time (BST). In 2026, this change is scheduled for March 29, with BST lasting until October 25, when the clocks will revert back to GMT.
Daylight Gains in March: A Gradual Increase
For those looking forward to more hours of daylight, a simple rule applies: the evenings gradually get lighter throughout March. According to timeanddate.com, the UK gains just shy of four minutes of additional daylight each day during this month. By the time March concludes, it won't just be an extra hour of daylight that people are enjoying; the cumulative effect leads to significantly shorter nights.
London's Daylight Timings
In London, on March 7, 2026, the sun rises at 6:32 am and sets at 5:51 pm, providing 11 hours, 18 minutes, and 30 seconds of daylight. By March 28, the day before BST begins, sunrise occurs at 5:45 am and sunset at 6:26 pm, extending daylight to 12 hours, 41 minutes, and 50 seconds. After the clocks spring forward on March 29, by March 31, sunrise will be at 6:38 am and sunset at 7:32 pm, resulting in 12 hours, 53 minutes, and 41 seconds of daylight.
Edinburgh's Daylight Patterns
Further north in Scotland, Edinburgh experiences similar gains, with about four and a half minutes more daylight each day in March. On March 7, sunrise is at 6:49 am and sunset at 5:59 pm, offering 11 hours, 10 minutes, and 30 seconds of daylight.

Extended Daylight Through Spring and Summer
This trend of lengthening daylight continues over the following months.

Edinburgh sees even more dramatic extensions, with daylight from 5:31 am to 8:49 pm on April 30, and from 4:36 am to 9:45 pm on May 31.
The Longest Day: Summer Solstice 2026
The peak of daylight occurs during the summer solstice. In London, on June 21, 2026, the sun rises at 4:43 am and sets at 9:21 pm, providing 16 hours, 38 minutes, and 22 seconds of daylight. Time and Date notes that this day is 8 hours and 49 minutes longer than the December solstice. In Edinburgh, the longest day offers 17 hours, 36 minutes, and 24 seconds of daylight, stretching from 4:26 am to 10:02 pm.
Impact on Sleep and the USA's Planned Switch
The Royal Observatory Greenwich clarifies that when British Summer Time begins, the clocks moving forward means we lose an hour of sleep. An easy mnemonic to remember is that clocks 'spring forward' in spring and 'fall back' in autumn. Meanwhile, the USA is set to make a similar switch, aligning with its own daylight saving schedule, though specific dates may vary by state and federal regulations.
As spring approaches, the anticipation for warmer weather and lighter evenings grows, with these detailed timings helping Britons plan their days and make the most of the extended daylight hours throughout 2026.
