Why is the UK one hour behind Europe?
Time is measured from the Greenwich meridan in London, west of that line is ahead of GMT (Greenwich Mean Time) and east of that line behind that time. Every 15 degrees east or west of Greenwich adds or subtracts an hour from GMT.
The time UK and Europe SHOULD be the same
France, Holland, Luxembourg and Belgium were all originally in the same time zone as the UK, but Germany changed their time to match the German zone (one hour ahead of the UK) during their occupation of those countries during the war.
History of Time Zones in the UK
The United Kingdom was one of the first countries to use a standard time for the whole country, instead of each place keeping its own local mean time. The UK's capital, London, changed from London Time to Greenwich Mean Time in 1847.
During the Second World War (1939-1945), British Double Summer Time - two hours in advance of Greenwich Mean Time (GMT) - was temporarily introduced for the period when ordinary daylight saving would be in force. During the winter, clocks were kept one hour in advance of GMT to increase productivity.
Originally Answered: Why are the UK in a different time zone than the rest of Western Europe? Because they are further west, like Portugal and the Canary Islands.
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.
Why do the clocks change? The clocks go forward for the summer because of a campaign at the beginning of the 20th century to change the clocks during the summer months, in a practice known as British Summer Time.
A proposal to repeal European Directive 2000/84/EC and require that member states observe their own choice of time year-round was initiated in September 2018. The United Kingdom left the EU before this reform became effective; the UK is subsequently free to make its own arrangements.
In the UK, Daylight Saving Time came into use in 1916, due to the costs of energy usage during the war. However, it was Canada that became the first country to implement Daylight Saving Time, in 1908. The US followed suit in 1918.
Outside of Europe and the U.S./Canada, changing the clocks is also practiced in Paraguay, Chile, Cuba, Haiti, the Levant, New Zealand and parts of Australia.
What is the smallest country with 2 time zones?
The Federated States of Micronesia is a single nation comprising more than 600 islands covering an area estimated by the World Bank to be 700 square kilometres (270 square miles). The country is divided into two time zones (UTC+10 and UTC+11), making it the smallest country by area to adopt more than one time zone.
So even though some states in the US and some European countries have been considering ending the concept of daylight savings time, it looks like the clock-change is here to stay in the UK.

Kiribati – pronounced Kiribas – is the only nation on Earth to permanently trespass into GMT+14: the earliest time zone in the world. You can think of Kiribati as the eternal land of tomorrow: if it's Sunday where you are, it's probably Monday in Kiribati.
Owing to the number of territories it governs beyond Europe, France has 12 (and for a period of the year 13) time zones. Metropolitan France operates on Central European Summer Time (UTC+2), while its dependencies range from Tahiti Time (UTC-10) in French Polynesia to Wallis & Futuna Time (UTC+12) in the South Pacific.
The time difference between London and New York is 5 hours. New York City is located in the UTC-5 time zone, during summertime it becomes UTC-4. The United Kingdom is therefore ahead of New York. This means that when it is midnight in New York, it is already 05:00 in the UK.
The main purpose of Daylight Saving Time (called "Summer Time" in many places in the world) is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening.
The British Army embraced the system in 1918, while the U.S. Navy adopted it in 1920, becoming the first U.S. organization to do so. The U.S. Army, however, did not start using it before 1942.
“Extended daylight hours allow outdoor restaurants, golf courses, parks and patio or rooftop bars to see sunsets well past happy hour and into dinner time, as opposed to forcing everyone into dismal darkness just before standard 5 p.m. business hours come to a close.”
The winter solstice occurs in the UK when the north pole reaches its maximum tilt away from the sun. The day only happens once a year in the UK but it does occur twice annually across the globe, once in the northern hemisphere and once in the southern hemisphere.
Why is day so long in England?
The times for sunrise and sunset in the United Kingdom are significantly influenced by the high location in the northern hemisphere. Relatively high in the north, the days are long in summer (June to September) and short in winter (December to March).
During British Summer Time (BST), civil time in the United Kingdom is advanced one hour forward of Greenwich Mean Time (GMT), in effect changing the time zone from UTC±00:00 to UTC+01:00, so that mornings have one hour less daylight, and evenings one hour more. This time zone is only used for DST.
HOW IS THIS POSSIBLE?! Well, France is in a time zone that's one hour ahead of the UK but geographically it's slightly to the east, meaning the sunset actually reaches Paris before it reaches London, even though it exists in a time that's later than the UK, so it's already later when the sun sets.
You can see that the most extreme time zones are +14 hours at Line Islands (Kiribati), and -12 hours in and around Baker Islands (US). Therefore, the maximum possible difference between times on Earth is 26 hours. That means that at 11:00 PM of a Monday in Baker Island, it is 1:00 AM of a Wednesday in Line Islands.
Geographically, Spain is on the same longitude as the United Kingdom, but rather than being on GMT – the same time zone as the UK – it's on Central European Time. There has long been a debate about time zones in Spain. In 2013, a parliamentary commission recommended that Spain should turn the clocks back one hour.
Japan, India, and China are the only major industrialized countries that do not observe some form of daylight saving.
“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.
It no longer serves its intended purpose of saving electricity, and DST negatively impacts our health, is overly complicated, costs us money, and puts our most vulnerable populations at risk. Americans deserve better.
Because of Arizona's hot climate, DST is largely considered unnecessary. The argument against extending the daylight hours into the evening is that people prefer to do their activities in the cooler morning temperatures.
Like many other countries around the world, Germany sets its clocks an hour forward in spring and an hour back in autumn.
Why is UK daylight Savings different from US?
This separate adoption of daylight savings time, and the fact the countries are situated in different timezones, plus their differing geography, led to the differences between the US and UK version of daylight savings time.
As New Zealand is one of the first countries in the world to receive the light of each new day and the US is one of the last, there is a significant time difference between the two countries.
The nation of Samoa also observed the same time as the Samoa Time Zone until it moved across the International Date Line at the end of 29 December 2011; it is now 24 hours (25 hours in southern hemisphere summer) ahead of American Samoa.
The country with the most time zones is France, mostly due to its various territories around the world.
Why do we have BST? British Summer Time (BST), otherwise known as daylight saving time, was originally devised to keep factories open for longer in the summer – since there was enough light to do so. It has also been suggested that BST reduces energy consumption.
Daylight Savings will start at 1am on Sunday, March 26 in 2023. Then the clocks 'spring forward' as we welcome the sunnier days of Spring and Summer. Following this, the clocks will go back again by one hour on Sunday, October 29.
In March 2019, the European Parliament voted to dispense entirely with biannual clock changes.
George Hudson invented modern DST, proposing it first in 1895.
According to the clock, the first areas to experience a new day and a New Year are islands that use UTC+14:00. These include portions of the Republic of Kiribati, including Millennium Island in the Line Islands.
UTC+14:00 stretches as far as 30° east of the 180° longitude line and creates a large fold in the International Date Line around the Pacific nation of Kiribati.
What countries are a day ahead of the US?
- Kiribati: Phoenix Islands.
- New Zealand (during Daylight Saving Time)
- Samoa.
- South Pole (during Daylight Saving Time)
- New Zealand: Tokelau.
- Tonga.
Russia was divided into eleven time zones in 1919, after the Bolshevik Revolution. Russia is a huge country by area expanding from east to west in the northern hemisphere and therefore, the country felt the need to adopt 11 time zones. The time in Russia ranges from UTC+02:00 to UTC+12:00.
The country was divided into eleven time zones in 1919, after the Bolshevik Revolution, with boundaries going along railroads and rivers, although these time zones have since been revised multiple times.
China, with a total area of 9.38 million square kilometres (3.62 million square miles) according to the World Bank, is the largest country to observe just one time zone: Beijing (or China) Standard Time.
The islands of Samoa, Tokelau and Tonga are 13 hours ahead of London, while the Line Island are a full 14 hours ahead. What's more bizarre is that these islands lie ACROSS the date line, so islands further west than them are over a whole day behind them in time. Confused yet?

Happen to be on the mainland? (Another Hawaiian quirk: We call the entire continental U.S. “the mainland.”) Hawaii, which is part of the Hawaii-Aleutian Time Zone, is three hours behind the West Coast, five hours behind the Midwest, six hours behind the Eastern Seaboard, and ten hours behind Greenwich Mean Time.
To save energy and help the war effort, the Summer Time Act 1916 advanced the clocks in the UK for 1 hour from May 21 until October 1 in the same year. Summer time, or DST, proved so popular that it was named British Summer Time (BST) and the seasonal practice kept.
British Summer Time (BST), otherwise known as daylight saving time, was originally devised to keep factories open for longer in the summer – since there was enough light to do so. It has also been suggested that BST reduces energy consumption.
The time difference between London and New York is 5 hours. New York City is located in the UTC-5 time zone, during summertime it becomes UTC-4. The United Kingdom is therefore ahead of New York.
Why is France an hour ahead of UK?
European Standardisation
Nowadays, France is on Central European Time (Central European Summer Time in summer) while Britain is always an hour behind on Greenwich Mean Time (or Western European Time).
GMT is the standard time zone in Ireland and the United Kingdom, including England, Wales, Scotland, and Northern Ireland. All of these countries use DST during part of the year, but under different names. The United Kingdom and its Crown dependencies use British Summer Time during the DST period.
From 1884 until 1972, GMT was the international standard of civil time. Though it has now been replaced by Coordinated Universal Time (UTC), GMT is still the legal time in Britain in the winter, used by the Met Office, Royal Navy and BBC World Service.
British people are very strict when it comes to punctuality.In Britain people make a great effort to be on time ,and it is considered to be impolite to be late, even a few minutes . If you are delayed ,be sure to inform the person you are supposed to meet .
Do countries beyond the UK change their clocks? Yep, indeed they do. It's not just the UK – it's a factor of more than 70 countries around the globe. Most European countries, including France, observe European summertime (Daylight Saving) – changing their clocks at the end of March and again at the end of October.
So even though some states in the US and some European countries have been considering ending the concept of daylight savings time, it looks like the clock-change is here to stay in the UK.
Daylight Saving in Europe
Time changes in Europe are synchronized. According to the current EU law, DST starts on the last Sunday of March and ends on the last Sunday of October.
