When exactly do the clocks go forward?
The clocks change on the last Sunday of March, moving forward by one hour.
What date do the clocks go back or forward?
When do the clocks go back? – The clocks change twice a year. Once in March when they go forward an hour, and once on the last Sunday of October, when they go back an hour. We will gain that hour at 2am on Sunday, October 29. And, while your smartphone and laptops will update automatically, analogue clocks and other digital clocks, like car and oven clocks, will need to be changed manually.
Do clocks go forward twice?
The leaves are turning brown and we’re turning our thermostats up. This can only mean one thing: British Summer Time is coming to an end, marked by the changing of the clocks. We’ve been changing the clocks for 100 years, though many of us remain in the dark about why we do it. The clocks change twice a year: forward one hour at 1am on the last Sunday in March, and back one hour at 2am on the last Sunday in October. During the summer, ‘Daylight Saving Time’ (DST) applies, while in the winter we revert back to ‘Greenwich Mean Time’ (GMT). The months in which DST applies are also known as British Summer Time (BST). When was Daylight Saving Time introduced?
Daylight Saving Time was introduced in 1916 in the UK. Why do we change the clocks?
One summer morning in 1905, British builder William Willett was riding his horse through the London suburbs. He passed house after house with closed blinds, and it suddenly came to him that the morning sunlight was going to waste. In 1907 he published the pamphlet “The Waste of Daylight”, which caught the attention of Parliament.
- Sadly Willett died of flu a year before DST became law, and never saw the fruits of his labour.
- So to put it simply, we change the clocks to make better use of natural daylight in the morning.
- During the summer time, we borrow an hour of daylight from the morning and shift it to the evening to reduce our energy consumption.
Hang on, didn’t Benjamin Franklin come up with the idea of Daylight Saving Time? Sort of. In 1784 the scientist and founding father of the United States published an essay called “An Economical Project for Diminishing the Cost of Light”. It argued that if people got up with the sun and went to bed earlier at night, we’d save on the cost of candles. It was somewhat tongue-in-cheek and didn’t go much further at the time. Does changing the clocks really save us energy?
There’s conflicting evidence around this. In 2006 the US state of Indiana shifted to daylight saving for the first time. Surprisingly, this led to a 1% increase in residential electricity use, possibly stemming from increased need for air conditioning.
In 2007, US Daylight Saving Time was extended by four weeks. A California study found this had little to no impact on energy consumption. However, a national study in 2008 did report that the extension saved about 0.5% of the nation’s electricity per day, an amount which could power 100,000 households for a year.

Why do we change the clocks?
Queen’s Maths and Physics lecturer and researcher, Dr Andrew Brown gets us up to speed on this timely conundrum Every October, across the UK and Ireland we get a glorious extra hour in bed when the clocks go back. Smartphones change time as if by magic and we have to remember to re-set the microwave and to whiz round to Granny’s house to diligently wind her mantelpiece clock back.
But what would happen if we decided to forgo the annual lie-in and just stayed in Irish/British Summer Time (BST) aka Daylight Savings Time all year? Well, while we wouldn’t notice any major difference at first, Dr Andrew Brown from Queen’s School of Mathematics and Physics explains that things would start to get bleak during the daily commute in late December.
“During the winter solstice, just before Christmas, we get less than eight hours of sunlight. If we didn’t put the clocks back, sunrise would be after 9.00am and sunset before 5.00pm. By putting the clocks back, it’s still dark when we’re going home, but the morning commute is a bit cheerier.”
Do you gain an hour of sleep when the clocks go forward?
The clocks are set one hour forward in Spring (October). This is often referred to as ‘spring forward’ to help us remember to turn our clocks forward. Although we gain an extra hour of daylight, we also lose an hour of sleep if we are not prepared. Moving our clocks can disrupt our sleep patterns.
Do you get more sleep if the clocks go back?
This is called Greenwich Mean Time (GMT), while when clocks go forward in summer it’s called British Summer Time (BST). When the clocks go back, the periods of light become shorter and the night air arrives quicker. Do we gain an hour of sleep when clocks go back? The answer is yes.
Do we gain or lose an hour in March 2023?
On Sunday 12 March 2023 clocks will be going forward one hour in most US states. The clocks moving forward means you will lose an hour of sleep, as your usual wake-up time of 8 a.m. will now be 9 a.m. on 12 March, making you late for whatever your plans are.
- This is the beginning of Daylight Saving Time which will last through to the beginning of November.
- The shift is always done on the weekend to limit the amount of disruption caused.
- Daylight Saving Time is just around the corner.
- The clocks will spring forward on Sunday, March 12th 2023 & most Americans will lose one hour of sleep.

Use these tips to prepare your sleep habits so you can be your Best Slept Self®. pic.twitter.com/n41zO7z2p7 — National Sleep Foundation (@sleepfoundation) February 24, 2023 Legislation has been passed in the Senate to permanently end the practice through the Sunshine Protection Act, which would end Daylight Saving Time.
Do we lose an hour of sleep in spring?
Whether you like it or not, daylight saving time begins on Sunday, March 12, when we move clocks forward by one hour at 2 a.m. Light will last longer into the evening, and the sun will rise later in the morning than during standard time. Many of us welcome the opportunity to spend more time outdoors with the extra hour of daylight in the evenings, but the annual ritual of “springing forward” also means that we lose an hour’s sleep.
This can leave many of us feeling sluggish and tired. “It is harder for most people to spring forward than to fall back,” said Sarah M. Richey, MD, service line medical director of Sleep Medicine at Kaiser Permanente in Colorado. “Essentially, we must start our day an hour earlier, and this temporary loss of sleep can cause tiredness and even worsen performance on tasks.
Springing forward may also have health consequences, as studies have shown that during the week after the start of daylight saving time there is an increase in heart attacks, strokes, and serious car accidents.” It’s not just adults who feel the effects of the time change.
“Children and teens are unfortunately not immune to the sleep deprivation caused by the time change,” Dr. Richey added. “They may have a harder time in school and be at increased risk of behavior problems. Teen drivers also need to be reminded of the dangers of drowsy driving.” Dr. Richey notes that our internal sleep cycles tend to normalize within a few days after daylight saving time starts, but there are some measures you can take to help your body adjust.
She shared 4 practical tips that can help you adjust to and minimize potential negative effects during the transition.
Gradually adjust your sleep schedule. Several days before the time change, consider setting your alarm 15 minutes earlier each day so that it’s not such an abrupt change on the day that daylight saving time starts. Create a bedtime routine. Establishing a relaxing bedtime routine can help your body recognize when the time is right to wind down and prepare for sleep. Get some morning sunshine. Get outside and soak up some sun first thing in the morning. This will help your brain produce melatonin earlier in the evening, helping your biological clock adjust to the change. Practice good sleep hygiene. Avoid lighted screens, caffeine, alcohol, and heavy meals in the hours before bed. These can disrupt your sleep patterns, making it more difficult to fall asleep or stay asleep.
Following these 4 simple tips can help you wake up with a spring in your step the first Sunday of daylight saving time, instead of dragging your feet for several days after the time change.
Why do the clocks change war?
So did William Willett get it through Parliament? – No, he didn’t. He campaigned for the clocks to change until he died of influenza in March 1915, but it wasn’t his love of golf that persuaded Parliament. In the spring of 1916, during World War One, the German army turned the clocks forward as a way of conserving energy.
Why do clocks go back at 2 not midnight?
Why does Daylight Saving Time start at 2 a.m.? – Map of time zones into which the US was divided after the adoption of Standard Time on 18th November 1883. Dated 19th century. Universal History Archive—UIG/Getty Images The reason Daylight Saving Time starts at 2 a.m., rather than midnight, is all thanks to the railroads : Amtrak, specifically.
- When the country first experimented with Daylight Saving Time in 1918 during World War I, there were actually no trains that left New York City at 2 a.m.
- On a Sunday.
- Sunday morning at 2 a.m.
- Was when they would interrupt the least amount of train travel around the country,” Downing says.
- There were even fewer freight trains in the early 20th century than there are today, so it made the most sense — changing the clocks at 2 a.m.
would not be disruptive. “And that was the sole reason we do it at that crazy time,” Downing explains. The railroad industry had already played an important role in timekeeping in the U.S., as North American railroads collectively adopted a Standard Railway Time in 1883, operating and dealing with time independently of Congress.

Why do the clocks go forward at 2am?
So, why does daylight saving time start at 2 a.m.? – Instead of turning the clocks at midnight, as might be expected, DST starts at the seemingly random time of 2 a.m. because of the railroads. When DST was introduced during World War I, it was one of the few times when there were no trains traveling on the tracks.
Do the clocks go forward all over the world?
Do other countries change the clocks? – About 70 countries have some form of daylight saving time, but it varies from region to region. Much of Europe and North America, as well as parts of South America and Australasia, change their clocks. However, many countries in Africa and Asia situated around the equator do not change the time.
The USA has daylight saving time, but not all states change their clocks. Arizona does not use DST (apart from the semi-autonomous Navajo Nation), and neither does Hawaii. Indiana introduced daylight saving time in 2006. In the United States, the clocks go back on 5 November 2023. In March 2019, the European Parliament backed a proposal to end the practice of changing the clocks in European Union states.
The proposal was originally meant to be introduced in 2021, but the amendment has not taken legal effect. EU states continue to use daylight saving time. The Royal Observatory at Greenwich is the home of time and space, the Prime Meridian and Greenwich Mean Time (GMT). But have you ever stopped to ask what is the Prime Meridian and why it is at Greenwich? Why are all time zones across the world based on GMT? What is longitude and why is the meridian moving? Written by Dr Louise Devoy, Senior Curator of the Royal Observatory at Royal Museums Greenwich.
This is John Harrison’s prize-winning longitude watch, completed in 1759. Harrison had been working on improving watches as a sideline to his development of the much larger H3. : When do the clocks go back?
When the clocks go forward is it lighter in the morning?
Why does the UK have British Summer Time? – Initially, the clocks were changed to save energy. Why waste electricity when there is perfectly good daylight to be used? The campaign for British Summer Time came about at the beginning of the 20th century.
Moving the clocks forward in the summer months gives us darker mornings but lighter, longer evenings. The idea was proposed in Britain by builder William Willett, says Dr Richard Dunn, senior curator for the history of science at the Royal Observatory Greenwich, Willett was “incensed at the ‘waste’ of useful daylight during the summer.
Though the sun had been up for hours as he rode his horse through Chislehurst and Petts Wood, people were still asleep in bed”. British Summer Time was adopted in Britain in 1916 to save fuel and money. Since then, Britain toyed with moving the clocks a number of times, including bringing them forward two hours ahead of GMT during the Second World War.
- They were also brought forward for periods in the spring of 1947, in line with fuel shortages.
- There was an experiment, between 1968 and 1971, which kept clocks one hour ahead of GMT all year round.
- Britain then reverted to our now familiar system of GMT in the winter and summer time between March and October.
In recent years, there have been renewed calls to scrap the changing of clocks, which critics say hits productivity and can lead to a spike in accidents by disrupting sleep cycles. However, the movement to scrap daylight saving time is itself divided between those who would prefer year-round GMT and brighter mornings, or year-round BST and brighter evenings – preventing any move towards a solution.
