It will officially feel like winter this weekend when the clocks go back an hour on Sunday morning.
That changes at 2am on Sunday 30 October, when clocks go back one hour to 1am.
Most smartphones, tablets and computers will make this change automatically.
This is good news for many as it means an extra hour in bed, while mornings will be brighter and evenings darker in the coming months.
When the clocks go back, the UK is officially on Greenwich Mean Time (GMT) and marks the end of British Standard Time (BST).
An extra hour in bed may be a comfort, but the bad news is that change is signaled by shorter days and longer, colder nights with winter now on the way.
The practice of changing the clocks was first started by Germany during World War I to save energy by extending daylight hours in the summer.
There won’t be any light nights again until Wednesday 26 March 2023, when the clocks go forward again to 1am.
An expert at Queen’s University Belfast said earlier this month that scrapping the Sunday shift could save households more than £400 a year on electricity bills.
Professor Aoife Foley said removing winter daylight saving time would save £1.20 a day because of lower demand on the National Grid at peak times.
