Londoners can look forward to more daylight in the evenings as the clocks are set to change to mark the start of British Summer Time.
The clocks go forward at 1am on Sunday, March 26 - meaning we will get an hour less in bed on Saturday night.
This means there will be daylight for longer in the evenings but the mornings will be darker for a time.
Greenwich Mean Time will resume from the last Sunday in October, this year on October 29, when the clocks go back one hour again.
In summer, the sun rises and sets one hour later than it would without daylight saving.
Summer solstice, the longest day of the year, will be on Wednesday June 21.
Daylight Saving Time was created in 1907 by William Willet in a bid to stop people wasting valuable hours of light in summer months.
That year he published a pamphlet named ‘The Waste of Daylight’, detailing his proposals to put clocks forward in April and back in September.
But his idea did not make it into law until 1916, when the Government made an urgent bid to make savings from the coal industry by reducing the need for artificial light during World War One.
British Summer Time began on May 21 that year, ending on October 1, when The Summer Time Act 1916 was passed by Parliament.
Willet died aged 58 in March 1915, so never saw that his invention became a reality.
It was Germany that first adopted the clock-changing plan, taking on the idea on April 30, 1916.
