Why do clocks go back at 2 a.m.? When UK summer time ends this weekend and if you get an extra hour in bed

Every year the clocks flip in autumn and forward again in spring — but change still grabs some people.

Fortunately your smartphone and most modern alarm clocks update the time automaticallyso you shouldn’t run the risk of accidentally arriving at work an hour early.

However, you will still have to go around the house to adjust your analog clocks and watches.

Currently, the UK works on British Summer Time (BST)which gives us more daylight in the evening. When the clocks roll back, we’ll be back to Greenwich Mean Time (GMT).

Here’s everything you need to know about why clocks come and goand when they will change in 2022.

When do the clocks go back in 2022?

This year the clocks go back in the UK on Sunday October 30a day earlier than last year, giving us an extra hour of light in the fall and winter darkness.

The change always happens at 2am on the last Sunday in October, and it gives you an extra hour in bed – which could be welcome if you overdid it at a Halloween party on Saturday night.

By making the switch over the weekend, in the middle of the night, it ensures limited disruption to schools and businesses.

GMT is the standard time zone all others in the world are referenced against, and will remain in place until spring, when we return to BST.

The clocks always move forward at 1am on the last Sunday in March, which means that in 2023 BST will start on Sunday March 26th. This gives us more daylight in the evening, but will unfortunately reduce your Sunday morning sleep.

Why does the UK have British Summer Time?

Initially, the clocks were changed to save energy and get people out. Why waste electricity when there is perfectly good daylight to use?

Countryside for British Summer Time emerged at the beginning of the 20th century. Moving the clocks forward during the summer months would give us darker mornings but brighter and longer evenings.

The idea was proposed in Britain by the manufacturer Guillaume Willetsaid Dr Richard Dunn, Senior Curator for the History of Science at the Royal Observatory, Greenwich.

Willett was “furious at the ‘wastage’ of useful daylight during the summer. Although the sun rose for hours as he rode through Chislehurst and Petts Wood, people were still sleeping in their beds.

British Summer Time was adopted in Britain in 1916 to save fuel and money.

Since then, Britain has tried to move the clocks a number of times, including moving them two hours ahead of GMT during World War II. They were also brought forward for periods in the spring of 1947, depending on fuel shortages.

There was an experiment, between 1968 and 1971, that kept clocks one hour ahead of GMT all year round.

Britain then reverted to our now familiar system of GMT in winter and summer between March and October.

Could BST be phased out in the UK?

While no one seems to be complaining about the aforementioned extra hour in bed in the fall, some have campaigns for british time To be lead to in line with other European countries at reduce accidents.

That would give it two hours ahead of GMT in summer and one hour ahead of winter.

Errol Taylor, chief executive of the Royal Society for the Prevention of Accidents (RoSPA), said in 2019: “Clock changes were first introduced in 1916 to reflect the needs of a nation at war. However, our priority now must be the prevention of road accidents that cause serious injury and death.

We know the time change kills people. During the working week, accident rates peak at 8 a.m. and 10 a.m. and at 3 p.m. and 7 p.m., with the afternoon peak being higher. Road accident rates increase with the onset of darker evenings and worsening weather conditions.

“And it is vulnerable road users – like children returning from school and cyclists – who would benefit the most. Anything we can do to bring those rates down has to be worth it.

“While we respect the opinions of those who want to keep the current system, we must not lose sight of the fact that lives are at stake.”

Others want to give up going back to October.

“One of the main reasons for not maintaining British Summer Time all year round, which would mean not setting the clocks back to October, is for people in Scotland, where the sunrise may not have place before 10 a.m.,” says Dr Dunn.

“Among other things, this would mean that children would travel to and from school in the dark, putting them at increased risk. Brighter mornings in winter are also better for postal and construction workers. and agriculture, who usually start working much earlier than many others.

Others say we spend so much time indoors – in offices, for example – that daylight saving time doesn’t really matter anymore.
