This year, Sunday March 31st marks the start of British Summer Time and clocks will go forward by one hour at 1 am – meaning that there’s more daylight in the evenings and less of it in the mornings.

BST is sometimes known as Daylight Saving Time.

Greenwich Mean Time (GMT) resumes from the last Sunday in October (October 27th, 2019) – when the clocks fall back one hour at 2 am.

Many use the phrase “spring forward, and fall (autumn) back” to remember when the clocks change.

This will mean getting one hour less in bed but will mean that there will be more daylight in the evenings from now on.

Many devices that are connected to the internet like tablets and phones will automatically update to the new time, but it is best to check to avoid getting caught out.

Daylight Saving Time was created by William Willett in 1907 to stop people wasting valuable hours of light in the summer months.

By setting the clocks back in winter, people get an earlier sunrise and earlier sunset.

In summer the sun rises and sets one hour later than it would without daylight saving.

In a pamphlet called “The Waste of Daylight” Willett wrote that clocks should be advanced by 80 minutes over four stages in April, and reversed the same way in September.

Germany became the first country to adopt the plan on April 30, 1916, in order to save on coal consumption, and on May 21, Britain followed.

The Summer Time Act of 1916 was passed by Parliament and the first day of British summer was reported as May 21, 1916.
