why do the clocks change at 2am

It's that time of year again where we turn the clocks backwards and all get one hour more in bed! The clocks will be going backward on Sunday 29 October at 2am - so you will probably be fast asleep tucked up in bed when it happens. When the clocks change like this, we are moving from what is called British Summer Time (BST) - also known as Daylight Saving Time (DST) or GMT+1 - back to Greenwich Mean Time (GMT). In 2016 it was a particularly special year as it marked 100 years since we first changed our clocks like this. Once you've had a read about why we do this, have a go at our quiz at the end to see how much you've managed to remember. Whose idea was it to change the clocks? An American politician and inventor called Benjamin Franklin first came up with the idea while in Paris in 1784. He suggested that if people got up earlier, when it was lighter, then it would save on candles. Benjamin Franklin, who first came up with the idea of moving the clocks according to daylight
But it arrived in the UK after Coldplay singer Chris Martin's great-great-grandfather, a builder called William Willett, thought it was a good idea too. In 1907, he published a leaflet called The Waste of Daylight, encouraging people to get out of bed earlier. Willett was a keen golfer and he got cross when his games would be cut short because the Sun went down and there wasn't enough light to carry on playing. When did we start changing our clocks? The idea of moving the clocks forwards and backwards was discussed by the government in 1908, but many people didn't like it so it wasn't made a law. Willett spent his life trying to convince people that it was a good idea, but it was only introduced in the UK in 1916 - a year after he died.


It was actually first introduced by the Germans in World World One, just before the UK did it. During World War Two, the UK actually used what was called British Double Summer Time (BDST), when the clocks were ahead by an extra hour during the summer. But this didn't last for very long. Now, the UK's clocks always go back by one hour on the last Sunday in October and forward by one hour on the last Sunday in March. Moving clocks like this is now done in some countries across the world, but many still don't do this. What do people think of it? Many people have different opinions about whether we should change our clocks like this. Some think having BST is a good thing because it saves energy, by making better use of natural daylight, and helps to reduce traffic accidents. Others don't like it because they argue that it doesn't actually save any energy, and it can make it darker when children are going to school in the morning, which can be dangerous. They also think it is not very good for our health. to see how much you've remembered about this! ItБs the bane of business meetings, dates, and early shift workers everywhere: Forget when the clocks go back, and you can find yourself severely out of time. So when do the clocks change? How does it differ around the world? And whatБs the reason? When should I change my clocks? In the U. S. , and nine other territories including Cuba and Bermuda, the clocks go backward by one hour on Sunday November 5, according to. This marks the end of daylight saving time (DST. ) The exceptions are Arizona and Hawaii, which do not use DST. At 2am in standard time where you are in the United States, the clock should jump back to 1am.


That means thereБll be more hours of sun at the start of the day, and an earlier sunrise and sunset. In 56 territories around the world, including throughout Europe, the clocks will go backward on Sunday, October 29. In Syria and Jordan, itБs October 27. In Iran, the clocks turn back on September 27. In Fiji and Tonga, daylight savingб time actually begins on November 5, so the clocks go forward. It then ends on January 21 next year. In Chile, they donБt go back until May 13 next year. Similarly, in most parts of Australia and Paraguay, DST began on October 1, and clocks wonБt go backward until next year, on April 1 in Australia and March 25 in Paraguay. And in Antarctica, New Zealand, and Samoa, DST began on September 24, and will end on April 1. In the rest of the world, territories donБt observe any daylight saving time. When did we start changing the clocks? The notion of shifting time around based on what the sun is doing is ancient. The Romans, for example, told the time in such a way as to continually adjust it around the behavior of the sun. But DST as we understand it today is a relatively recent invention. In 1895, a New Zealander scientist called George Hudson presented a paper to the Wellington Philosophical Society that suggested a system of Бseasonal time adjustment,Б according to. Initially, he was ridiculed, but after New Zealand first successfully trialed daylight savings in 1927, Hudson was given a medal for his work in 1934. The haters will always come around eventually if your idea is good enough. According to, a Canadian district called Port Arthur in Ontario turned their clocks forward in July 1908, the worldБs first actual DST period.


Germany and Austria were the first whole countries to adopt the system, in 1916. They were followed by the U. K. , France, and others. The U. S. joined the bandwagon in 1918. Why do we do it? That first rush of countries was sparked by World War I. In Germany, the U. S. and elsewhere, the idea was adopted as a temporary emergency measure that was supposed to conserve fuel and give more hours of productive work. Most countries dropped it once the fighting was over, but the Brits were an exception: They kept it on, and in 1925 officially made it permanent, calling it British Summer Time (BST). In the U. S. , DST came backб with the return of warБit was taken up in 1942 as part of the battle against the Nazis. Then, up until 1966, states could decide whether to adopt it or not. Following that, the Uniform Time Act spread it across most states. Proponents argue that using DST saves on energy costs, though the evidence is disputed. Meanwhile detractors point to the hassle involved, both on a personal level, and on a large scale in industry where it can make organizing suppliers and workers more difficult. Why is it different around the world? Some 172 countries just donБt see the point: TheyБve clearly never been convinced of the case for it. Among theб countries that do follow it, summertime is different in the Northern and Southern hemispheres, so that explains some of the biggest discrepancies. Otherwise, itБs simply a function of what governments decided in the past. node-type-article. article-body > p:last-of-type::after,. node-type-slideshow. article-body > p:last-of-type::after{content:none}
