Here's everything you need to know about the autumn time change.

When do the clocks go back in 2021?

The clocks are due to go back in the early hours of Sunday, October 31.

What time will they change?

The clocks will set everyone back at 2am as the UK reverts to Greenwich Mean Time (GMT) by going back an hour to 1am.

This will mark the end of British Summer Time (BST).

Why does the time change?

The clocks go forward in the spring as we switch to British Summer Time (BST), which is also known as Daylight Saving Time.

This was first introduced by an Edwardian builder called William Willett in 1907.

William noticed that during the summer people were still trying to sleep once the sun had risen and wanted everyone to stop wasting precious daylight hours.

Back in 1907, the clocks were set to Greenwich Mean Time (GMT), meaning it was light by 3am and dark by 9pm in the midst of summer.

The builder, who was a keen supporter of the outdoors, proposed the clocks should be advanced by 80 minutes during April and then reversed in September.

British Summer Time (BST) in 1916 began in the UK on May 21 and then ended October 1.

Sadly, William did not live to see his idea in action as he passed away in early 1915.

Is there a future for Daylight Saving Time?

There have been many trials over the years from double summertime (GMT+2 hours) during the Second World War to permanent British Summer Time (GMT+ 1 hour) during the late 1960's.

The current system has been in place since 1972, with the changing of the clocks to begin at the end of March and to revert in October.

The debate of whether Daylight Saving Time could come to an end stretches far into the past but there are currently no plans to scrap British Summer Time(BST).
