The clocks will soon go forward an hour.

It marks the change from the current Greenwich Mean Time to British Summer Time.

Whether you're focussing on the fact you're losing an hour in bed or gaining an extra daylight, here are some things you'll want to know.

1) When do the clocks change?

At 1am on Sunday, March 25, the time will spring forward an hour.

This will mark the beginning of British Summer Time.

You then won't need to touch them until 2am on Sunday, October 28.

That's when they need to go back again Greenwich Mean Time.

2) What is British Summer Time?

British Summer Time is what the name given to the time once the clocks have been put forward.

The impact of the change means we get more of an opportunity to enjoy the daylight once we finish work.

3) Are there any pitfalls?

It depends how you look at it.

With there being more sunlight in once the clocks have been adjusted you will also a shorter period of nightfall in the evenings.

This could mean that you might lose out on around an hour of sleep on Sunday.

Alternatively you could look at it as an opportunity to enjoy the lighter evenings.

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

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

That's the same for the time on your watch as well.

But when it comes to the clocks on your devices and smartphones, they should update themselves automatically.

5) Will it always be like this?

The change in time was introduced after the First World War.

It was thought it would reduce the use of coal.

An experiment a couple of years ago found when the clocks weren't changed back to Greenwich Mean Time in autumn showed there were more accidents.

They happened in the morning because of a lack of sunlight in some parts of Britain.

So it looks like the changing time zones are here to stay.
