It's already starting to look and feel like autumn outside and you might be wondering when the clocks go back.
This year, we change the clocks back one hour at 2am on Sunday, October 29, meaning we get an extra hour in bed (unless you are the parents of young children).
This means the mornings will be lighter for a while and it will be starting to get dark from early evening.
The UK will move from British Summer Time (BST) back to Greenwich Meantime Time (GMT) until the clocks go forward again in the spring.
How do I remember which direction to change the clocks?
To avoid confusion, simply memorise the simple phrase 'spring forward, fall back'.
The clocks always go forward an hour on the last weekend in March in spring, and go back on the final weekend of October in autumn.
Why do we change the clocks?
The moving of the clocks was first introduced during the First World War by Germany and Austria, and then by the allies, to save on coal usage.
It was invented by George Vincent Hudson, a New Zealand entomologist in 1895, while British businessman William Willett is also credited with the idea as a way of getting up earlier and so having more daylight hours after work.
While the UK has always had daylight savings time since it was first introduced, it came into widespread use across the world during the 1970s because of the energy crisis.
