The engulfing of autumn is firmly upon us as the days gradually get shorter.
The darker mornings, earlier sunsets and rainy days all herald the end of British Summer Time (BST), meaning the clocks will have to be put back.
And while that does mark the official start of the colder months and lead into winter, it does at least mean everyone will get an extra hour in bed when the time-change happens.
But that bit of additional sleep comes with knowing that the nights will grow even longer, with sunsets creeping down towards the nadir of 4pm (and even before) in some areas of the UK during the lowest ebbs of winter.
Here's everything you need to know about the clocks going back, including what day it will happen.
When do the clocks go back?
In the UK, the clocks always go back by one hour at 2am on the final Sunday of October.
This means that the clocks will go back on Sunday 30 October 2022.
It means that when the clock strikes 2am on that day, it will skip back to being 1am again.
One way of remembering which way the clocks will change is "spring forward, fall back".
When the clocks go back, the UK will return to being on Greenwich Mean Time (GMT) — so named because the recording line goes through the south London borough.
It will revert from having been an hour ahead of GMT while on BST.
The shift to what is sometimes known as Daylight Saving Time during the summer months creates more daylight in the evenings and less in the mornings.
But as the cooler climate comes in, the move back to GMT from October provides slightly brighter mornings but with the caveat of longer evenings.
Why do the clocks go back?
The act of turning the clocks back an hour in October has been a regular activity since the years of World War I.
It restores the UK's usual time pattern after having put the clocks forward an hour in March.
The idea of putting the clocks forward every summer was originally acted upon to help people use less fuel by allowing them to make use of an extra hour of light each evening.
The concept had gained traction at the turn of the 20th century but the need to conserve fuel for the war effort led to it being brought into law in 1916 as part of the Summer Time Act.
When it comes to putting the clocks back this weekend, many smart devices such as phones, TVs and tablets will automatically reset, but analogue clocks, watches and other appliances will need winding back.
It’s not just the UK that puts the clocks back every autumn.
All European countries, except for Belarus and Iceland, use daylight saving time during the summer months, switching their time on the same night as the UK.
However, a vote in the European Parliament in 2019 to scrap daylight saving time could see the majority of countries on the continent stop going through the bi-annual change — although the bloc has admitted the change is not a priority.
There have been attempts to ditch using GMT in the past in the UK and to instead live permanently on BST.
Between 1968 and 1971, Brits kept the clocks one hour ahead of GMT all year round.
However, this saw an increase in morning road injuries, especially in Scotland where the sunrise is later, so it was decided to stick to the standard seasonal clock changes.
Despite this, Conservative MP Sir Greg Knight calls for a debate on keeping BST twice a year to coincide with the changing of clocks.
Other lobbying groups have argued it is time for a fresh trial to see whether permanent BST is feasible, with some arguing it could boost the economy.
