The clocks are to change tonight as it becomes British Summer Time (BST), which often happens on the last weekend in March.
But which way do they go? In the spring, the clocks always go forward meaning the evenings become much lighter.
However this means that people will lose an hour of sleep, meaning an earlier night is needed.
In October, they go back to move to Greenwich Mean Time (GMT), meaning Britons get an extra hour.
When do the clocks change today?
Britons wanting to change their clocks themselves will need to do it on Sunday March 25 at 1am.
The change means it will become 2am instead on the Sunday.
Most electronic devices such as mobile phones and computers will do this automatically, although other devices such as ovens and cars often don’t.
The tradition of changing clocks came into place in 1916, after it was proper by builder William Willett to save money on lighting costs.
What affect does the clock change have on your health?
By changing the clocks, people have less sleep than they may need, and caught caught tiredness.
However a study by the University of Alabama also found that it heart attack risks increase by 10 per cent on the Monday that follows.
This is due to the sleep deprivation that the body is put through.
Professor Young, speaking to The Telegraph, added: “Exactly why this happens is not known but there are several theories.”
The clocks changing means that Britons will start to see the light much longer in the day.
This also means the days are longer as they lead into summer, something that often happens in the spring season.
Despite the recent bad weather and snow in the UK in the recent months, the clocks going forward will last for six months.
It means that the mornings will also be lighter for early birds and workers.
