The nights have been getting darker... So that means it's almost time to put the clocks back.
This is because the Autumn Equinox has been and gone, so British Summer Time (BST) will soon come to an end and we will more back to Greenwich Mean Time (GMT).
But when exactly do the clocks need to be changed, and what is the reason for this?
When do the clocks change?
The clocks will need to be changed on the last Sunday in October, as that is when British Summer Time will come to an end.
Therefore, you will need to put the clocks back by one hour on Sunday, October 29, in 2017, at 2am.
This means that 2am will go back to being 1am, giving you an extra hour in bed.
Moving the clocks backwards by one hour, takes us back to Greenwich Mean Time - meaning that it will get dark even earlier in the evenings.
Why do we do this?
Our daylight hours more than double during the course of the year.
Our maximum 16 hours and 50 minutes of sunlight on the longest day in June dwindles to just seven hours and 40 minutes in December.
British Summer Time, which is also known as Daylight Saving Time, was first proposed by William Willett in 1907 to make more use of the daytime and prevent people wasting it first thing in the morning during the summer.
So he published a pamphlet called The Waste of Daylight and spent the rest of his life trying to convince people that his scheme would work. But when he died in 1915, it still hadn't been taken seriously.
It was in 1916 that Germany introduced the scheme and Britain – which was at war with Germany and couldn’t afford to miss a way of saving fuel and money – quickly followed suit on May 21, 1916.
How long do the clocks stay on GMT?
The clocks will go forward again on the last Sunday of next March at 1am, meaning we lose an hour of sleep.
This is designed to make better use of the long sunlight hours over the summer months.
