The clocks go forward this Sunday, marking the beginning of the daylight saving period.
It will mean the time jumps to 2am as the clocks turn to 1am on 30 March – and yes, bad news, you will lose an hour of sleep.
But the extra hour of daylight will mean longer, lighter evenings from next week.
“Spring forward, fall back” has been part of our calendar for more than 100 years – but whether we should continue the practice is hotly debated.
But why do some people get so up in arms about the clocks changing – and why do we do it in the first place?
Here is what you need to know – including how to prepare ahead of this weekend’s clock change.
Why do we have daylight saving time?
The change to British Summer Time (BST) – also known as daylight saving time (DST) signifies the end of Greenwich Mean Time (GMT) in the UK.
It lasts from the last Sunday in March until the last Sunday in October, when the clocks go back an hour.
It is common belief that DST was introduced to help give farmers more daylight hours to work in the fields. But this is not exactly true.
George Hudson, a New Zealand entomologist – someone who studies insects – first campaigned for more evening sunlight back in the 1890s, so he could study his beloved bugs. It was the first time changing the clocks around the seasons had been suggested seriously.
Jump to 1907 and British inventor William Willett – the man credited with bringing daylight saving to the UK – self-published a pamphlet called The Waste Of Daylight, in which he outlined his frustration with not getting the most out of summer days.
He initially proposed that clocks jump forward by 80 minutes in four incremental steps in April and reversed the same way in September – but he died before any law was implemented in the UK.
The first country to adopt DST was Germany in 1916, during the First World War. The UK followed suit a few weeks later.

How does daylight savings affect your health?
Since the implementation of DST, and particularly the clocks going forward in spring, various studies have found that darker mornings and lighter evenings can cause havoc with some people’s bodies.
In fact, sleep and dream researcher Charlie Morley said there is “overwhelming” evidence of the health issues the switch can cause.
“What research shows is what a massive effect on the body and mind, just one extra hour [of sleep] can have,” Mr Morely told Sky News.
One study cited by the American Heart Foundation found there was a 24% increase in heart attacks on the day following the switch to daylight saving time – however the opposite effect has been identified in autumn, when the clocks go back.
Another from 2016 in Finland found there were 8% more hospital admissions for the most common type of stroke in the two days after the shift to daylight savings.
Researchers also note those suffering strokes and heart attacks were likely to already be at higher risk.
When asked what symptoms losing an hour of sleep can lead to, Mr Morely said: “The interesting thing is when you get a really short amount of sleep, like four hours or less, the fear centre of the brain, known as the amygdala, becomes 60% more active.
“This can make it seem like everything is annoying, threatening or in conflict. So if you lose an hour of sleep, you might see an increase in the amygdala response, making you more grumpy and tetchy.”
Whether to keep daylight saving or not has been a hotly debated question for many years, but was reignited in October last year, when the British Sleep Society called on the UK government to abolish the twice-yearly clock changes.
In an article at the time, researchers said due to the negative effect DST has on circadian and sleep health, the UK should abolish the change altogether, and reinstate standard time throughout the year.
In reality, only about a third of the world’s countries practice daylight saving time, according to the Pew Research Center.
US President Donald Trump wrote in a post on Truth Social last December that he wanted to scrap DST. His secretary of state Marco Rubio has also called the ritual of changing time twice a year “stupid”.

The European Parliament has also previously voted for all EU member countries to scrap DST, but after the Parliament and EU Council couldn’t reach an agreement on the legislation, it never became law.
One of the few places that doesn’t follow DST in Europe is Iceland, due to its location and extreme variations in daylight throughout the year.
How to prepare for clock changes and the ‘golden rule’ of napping
Mr Morley says it is impossible to make up for lost sleep, but those worried ahead of daylight saving time can “front load sleep”.
This involves someone getting “really good, quality sleep before entering a period of bad sleep”.
Exposing yourself to natural sunlight first thing in the morning, eating meals based on the time of day it is where you are, minimise the use of caffeine and exercising can also all help treat negative effects of losing an hour of sleep.
Mr Morely added that napping can also be an effective way of dealing with sleep deprivation – but there are some hard and fast rules.
“The two golden rules of napping are it needs to be under an hour, so between 20 minutes and 60 minutes, and the nap needs to end six hours before you intend to go to bed again,” he explained.
“There is a chemical called adenosine, which is known as the tiredness chemical, and it takes around five to six hours to build up. So if you want to go to bed at midnight, as long as your nap ends up 5pm you have got enough time for adenosine to build up, and you will be tired enough to go to bed.”
Hayat Tahrir al Sham (HTS) went from a jihadist movement once aligned to al Qaeda to forming the official government of Syria.
It was a monumental transformation for them, their country and the wider Middle East.
But potentially too for British people who went to Syria– and who were stripped of their citizenship as a result, on the grounds of national security.
Tauqir Sharif, better known as Tox, went to Syria in 2012 as an aid worker. He was accused of being part of a group affiliated with al Qaeda, which he denies, and the then-home secretary Amber Rudd deprived him of his British citizenship in 2017.
“As of now, I am deprived of my UK citizenship but I’m not a convicted terrorist – and the reason for that is because we refused, we boycotted, the SIAC [Special Immigration Appeals Commission] secret courts, which don’t allow you to see any of the evidence presented against you,” he said.
“And one of the things that I always called for was, look, put me in front of a jury, let’s have an open hearing.”

HTS is still a proscribed terrorist organisation but the British government has now established relations with it.
Foreign Secretary David Lammy travelled to Damascus to meet the jihadist-turned-Syrian interim president – the man who swapped his nom de guerre of al Jolani for Ahmed al Sharaa.

If the UK government takes HTS off the terror list, what does that mean for those who lost their citizenship after being accused of being part of it?
People who joined HTS are only a subset among the scores of people who have had their citizenship revoked – a tool the UK government has been quick to use.
According to a report by the Parliamentary Joint Human Rights Committee, the UK “uses deprivation of citizenship orders more than almost any country in the world”.
The peak of that was in 2017, and mainly in relation to Syria – especially in the case of people joining Islamic State, perhaps most famously Shamima Begum.

And because people cannot be made entirely stateless, and need to have a second nationality, or be potentially eligible for one, there are worries of racism in who the orders apply to.
Countries like Pakistan and Bangladesh offer dual nationality, whereas other nations do not. In 2022, the Institute of Race Relations said “the vast majority of those deprived are Muslim men with South Asian or Middle Eastern/North African heritage”.
Legal grey areas
Sky News submitted Freedom of Information requests to the Home Office asking for a breakdown of second nationalities of those deprived of citizenship, but was refused twice on national security grounds.
The independent reviewer of terrorism legislation, Jonathan Hall KC, told Sky News there are issues around transparency.
“I do think there is a problem when you have people whose relationship with the country that they’re left with is really technical and they may never have realised that they had that citizenship before and may never gone to that country,” he said.
“Me and my predecessors have all said, owing to how frequently this power is used, it should be something that the independent reviewer should have the power to review. I asked, my predecessor asked, we’ve both been told no, so I agree there’s a lack of transparency.”

“We can’t sort of go through previous cases nitpicking through it, wasting time and money to bring it up to date,” he added.
“We can’t be naive because the intent to go out, the decision to go in itself is a huge decision for them. So it shows commitment when they’re there, they then, if they take an active participation in the organisations that they’ve been accused of joining, again, that involves training and perseverance and dedication to the cause.”
But those born and raised in Britain, who joined the same cause, and lost their citizenship as a result, might reasonably ask why that should remain the case.
Criminals face being banned from pubs, sports grounds and concerts under new government plans to give judges powers to pass tougher community sentences.
The new measures, which would apply to people in England and Wales, “should remind all offenders that, under this government, crime does not pay”, Justice Secretary Shabana Mahmood said.
Offenders’ freedom could also be curtailed with limits on driving, travel bans and restriction zones confining them to specific areas, the government said.
Similar measures could also apply to prisoners let out on licence, while drug testing would be expanded to include all those released, rather than just those with a history of substance misuse.
While judges are currently able to impose limited bans for specific crimes, such as football bans for crimes committed inside a stadium on match day, the new measures would allow for such bans to be handed down for any offence.

The justice secretary said: “When criminals break society’s rules, they must be punished.
“Those serving their sentences in the community must have their freedom restricted there too.

“These new punishments should remind all offenders that, under this government, crime does not pay.
“Rightly, the public expect the government to do everything in its power to keep Britain safe, and that’s what we’re doing.”
The proposals are part of the Labour government’s efforts to tackle overcrowding in prisons.
Back in June, it emerged that prisoners were to be transferred to lower security jails in an effort to ease overcrowding, as part of a new measure quietly unveiled by the government.
Sky News reported earlier this month how the prison system was close to collapse on a number of occasions between autumn 2023 and summer 2024, according to an independent review by former chief inspector of prisons, Dame Anne Owers.
The report said there was a systemic problem which has led to recurring prison capacity crises over the last 18 years.
Protesters have gathered across the country as groups demonstrated against asylum seeker housing and were met by anti-racism campaigners.
Demonstrations under the Abolish Asylum System slogan were held in England, Scotland and Wales, including in Bristol, Exeter, Tamworth, Cannock, Aberdeen, Mold, Perth, Nuneaton, Liverpool, Wakefield, Newcastle, Horley and Canary Wharf.
Counter-protests were also organised by campaign group Stand Up to Racism.

The anti-racism protesters chanted “say it loud, say it clear, refugees are welcome here” and held signs calling for solidarity and to “stop deportations”.
The Stand Up to Racism protesters were shepherded into a smaller area as they continued to chant: “No hate, no fear, refugees are welcome here”, which was met with “No they’re f****** not” from the other side of the street.

Stand Up to Racism Scotland said it had achieved “victory” in Perth, with more than 200 gathering to oppose the Abolish Asylum System demonstration.
In Liverpool, a dispersal order was issued to try and contain the protests.
Saturday’s events come amid continued tension around the use of the hotels for asylum seekers.
Regular protests had been held outside the Bell Hotel in Epping, Essex, which started after an asylum seeker housed there was charged with sexually assaulting a 14-year-old girl on 10 July.
Hadush Gerberslasie Kebatu, 38, was charged with trying to kiss a teenage girl and denies the allegations. He is due to stand trial later this month.
