Every year, the clocks go back in October when British Summer Time ends.
They go forward in March each year to give an extra hour's daylight in the evenings.
But GMT (Greenwich Mean Time) begins at 2am on the last Sunday in October, when clocks should be set back an hour.
That means an extra hour in bed, but you'll soon notice the nights start drawing in.
This year's date is Sunday, October 29.
Most smart devices such as phones, computers and televisions should now update themselves in order to show the correct time, but others like your car, oven and microwave will need to be adjusted manually.
We will remain on GMT until March 25 2018 when the clocks go forward once again.
