This is when and why the clocks go forward for British Summer Time

It's time to dig out the instructions for the oven and try and reset the clock.

Here's everything you need to know about why the time changes in the spring as the clocks go forward by one hour for British Summer Time (BST).

When do the clocks change?

On Sunday, March 27 at 1am the time rolls forward an hour so it is instantly 2am.

You can then leave your clocks in British Summer Time mode - also known as Daylight Saving Time - until 2am on Sunday, October 30.

This will be when they will need to fall back when the country returns to Greenwich Mean Time.

Why do the clocks change in Spring and Autumn?

The idea was first proposed by Benjamin Franklin, but was later introduced to Britain by the builder William Willett.

Willett's pamphlet 'The Waste of Daylight' argued that if the clocks were changed twice a year people would sleep better, save money on artificial light, and enjoy more daylight.

The idea was introduced into UK law in 1916.

Now the clocks change on the last Sunday of March and October.

Are there any downsides?

That depends on how you look at it.

The evenings are longer, more time to spend sitting out in the garden after work, but you'll have to wait that bit longer for sunrise shot for your Instagram.

Plus you do lose an hour of sleep this Sunday... and on Mother's Day, that just feels a little unfair.

The clocks won't update themselves... well, some might!

Most of the clocks in your home will need to be updated manually.

Remember to change the time on your watch as well - if it's not a smart watch - as well as your car and heating systems. We might be going through a warm spell right now, but chilly mornings aren't quite a thing of the past just yet.

The clock on electronic devices and smart phones will most likely change themselves automatically.
