It's time to dig out the instructions for the oven and try and reset the clock.
Here's everything you need to know about why the time changes in the autumn.
When do the clocks change?
On Sunday, October 25, at 2am the time rolls back an hour.
This reverted the clocks back to Greenwich Mean Time.
You can now leave them until 1am on Sunday, March 28, next year.
This will be when they will need to spring forward again for British Summer Time.
Why do the clocks change in Spring and Autumn?
The idea was first proposed by Benjamin Franklin, but was later introduced to Britain by the builder William Willett.
Willett's pamphlet, 'The Waste of Daylight', argued that if the clocks were changed twice a year people would sleep better, save money on artificial light, and enjoy more daylight.
The idea was introduced into UK law in 1916.
Now the clocks change on the last Sunday of March and October.
Are there any downsides?
That depends on how you look at it.
The mornings are brighter and sunset will be an hour earlier making your days shorter.
But you did get an extra hour of sleep this Sunday to make up for it.
Will it always be like this?
Well, that really depends on Brexit.
For now, clocks in the EU switch between winter and summer time.
However, plans were put forward and voted on last year to scrap daylight saving time in EU member states.
Plans have since been postponed, so there is no way of telling whether it will progress into law while the UK is still part of the EU - or whether it will become law at all.
The clocks won't update themselves... well, some might!
Most of the clocks in your home will need to be updated manually.
Remember to change the time on your watch as well - if it's not a smart watch.
However, the times on your devices and smart phones will most likely change themselves automatically.
