When do the clocks go forward and when will they change back in 2020? We answer your time change questions

ONCE a year the clocks go forward an hour as Britain changes to daylight saving time.

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

When do the clocks change?

On March 29, 2020, the clocks will go forward one hour at 1am.

When the clocks turn forward an hour we enter British Summer Time or BST.

It means there's more daylight in the evenings, and less in the mornings.

It's also sometimes known as daylight savings time.

The clocks always go forward one hour on the last Sunday in March.

The UK observes the clock changing twice a year, when it goes back to GMT in October.

Will my phone update automatically?

Yes – if you have an iPhone then it will have automatically changed if you have your "date and time" options set to "set automatically".

For all other smartphones, network operators should change the time accordingly if you have automatic updates set to your phone.

However if you're still using a regular keypad brick-style mobile you might need to change your date and time manually.

Sadly, the clocks going forward means you lose an hour of sleep

Why do the clocks change twice a year?

The clocks go forward to make better use of daylight.

When changed to BST, we move an hour of daylight from the mornings to the evenings.

In the winter the clocks go back to signal the approach of winter and fewer daylight hours by ensuring there’s more daylight in the mornings and less in the evenings.

To help you remember which is which, think “spring forward, fall back”.

Why was the time change introduced?

British Summer Time came into existence with the Summer Time Act that was passed by Parliament in 1916.

Germany was the first country to adopt the plan on April 30, 1916, and on May 21, Britain followed suit, during the height of the First World War.

The campaign which led to the creation of BST and Daylight Savings Time (DST) was started by William Willett in 1907 in a bid to stop people wasting valuable hours of light in the summer months.

By setting the clocks back in winter, Brits 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 suggested clocks should be advanced by 80 minutes over four stages in April, and reversed the same way in September.

Supporters at the time of the proposal argued the scheme would save energy by reducing domestic coal consumption.

They also said it would increase supplies available for the huge manufacturing cost of the war effort.

It has been in place ever since – despite criticism from some groups.
