To make up for the shortening days, the clocks will go back across the UK to give us an extra hour of much needed sunlight as we approach the darker months.
Here is everything you need to know about clock changes in the UK this year.
In autumn the clocks will go back at 2.00am on the final Sunday of October, which this year falls on Sunday, October 29.
It means an extra hour in bed for your Sunday lie-in and will give an extra hour of daylight as the darker nights roll in.
In the majority of cases, the days of manually changing your clocks are long gone.
Any device connected to the internet such as smartphones, televisions, laptops and tablets will change automatically.
However – be careful – alarm clocks, car radios and other devices not connected to the internet will need to be adjusted manually.
The principal reason we change the clocks is to get the most out of the daylight.
The first clock change was introduced by the German government in 1916 during the first world war as a means of saving energy – the longer the daylight hours lasted, the less electricity required.
Many European governments followed suit, including Britain, and so was born BST, with the current system in place since 1971.
