The world keeps turning, just like before. To maximise the benefit of having extra daylight, it matches the warmest and longest days of the year. Most devices with internet connection, such as smart phones, should automatically update themselves.
However, watches and clocks in cars and kitchens, for example, won't change automatically so make sure you are ready to wind forward. Curator of the Royal Observatory, Louise Devoy, explains what happens in Greenwich when the clocks change:.
Actually, I have very little work to do when the clocks change! We deliberately keep most of our historic clocks on GMT all year round as they were mainly used before the first daylight saving came into effect in The most significant change is our Dolphin sundial which needs to be adjusted four times a year: at the solstices June and December and when the clocks change March and October.
However, many countries in Africa and Asia situated around the equator do not change the time. In the USA the clocks go forward on the second Sunday in March and back on the first Sunday in November, but not all states change their clocks.
In March , the European Parliament backed a proposal to end the practice of changing the clocks in European Union states. If the proposal is adopted, EU nations could change the clocks for the last time in His rather complicated plan was to advance clocks by 80 minutes, in 4 separate moves of 20 mins each. Keep track of time with Royal Observatory Greenwich watches, and our famous Shepherd Gate clock, reproduced for your wall at home.

The use of the different dial rims for Greenwich Mean Time and British Summer Time and of the two different hour-plates with the hour-lines marked, means that the Dolphin Dial at the Royal Observatory is always accurate to the nearest minute. Of course, not everyone is tucked up in bed at 2am; employees who are scheduled to work a night shift at this time may find themselves working an extra hour when the clocks go back to 1am.
Night workers are often advised to check their contracts and discuss the situation with their employer. By law however, night workers must not work more than an average of 8 hours in a hour period. 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.
Virgin Islands and American Samoa. There are currently about 70 countries that participate in Daylight Saving Time , though not necessarily on the same schedule as the United States. Determining who recognizes Daylight Saving Time and when can sound like a very complicated math word problem. In the southern hemisphere , where the summer season begins in December, Daylight Saving Time is recognized from December through March. Advocates in support of Daylight Saving Time suggest that in addition to reducing crime and automobile accidents, extended daylight hours also improve energy conservation by allowing people to use less energy to light their businesses and homes.
Opposing studies argue the energy saved during Daylight Saving Time is offset by greater energy use during the darker autumn and winter months. Ready to spring forward or fall back? Check out the following activities with a friend or family member:. We have over Wonders of the Day, Alejandro! You can search topics HERE! We're sorry you feel your teacher is being mean, Someone.
We recommend you talk with your parents about it and maybe you can communicate with your teacher about how you feel. Oh, who are we kidding? Sometimes the one in the car is left for six months because it'll be right then! All have to do with the hemispheres of the earth. Thanks for sharing your thoughts, Rmot. Though some researchers do not support Daylight Saving Time since the energy saved during Daylight Saving Time is offset by greater energy use during the darker autumn and winter months , there are advocates in support of Daylight Saving Time.
These advocates have found that the extended daylight hours reduce crime and automobile accidents, as well as improve energy conservation. Hi, Wonder Friend!! Is there a specific question you have about this Wonder? We try to make our Wonders for everyone including kids! Thank you so much for sharing, Alan!
We are updating our Wonder of the Day with this information!! Well, yes and no. By changing the time you are altering how early the sign rises and sets. That means the day seems like it starts and ends earlier if the sun is rising and setting earlier.
But yes, you still have the same amount of daylight in a day. Great point, Bob! That would make things simpler, Sherry, but then we'd miss out on the fun of springing forward and falling back! I see no advantage of moving our clocks back in the fall. We then use more electricity in the fall. Why not conserve power all year around. Thank you for sharing your opinion, Dan. There continues to be debate about the effectiveness of Daylight Saving Time; perhaps in the future we'll see a change to the system.
We're glad you visited Wonderopolis, Dan! We're glad to hear your thoughts, john! We hope this Wonder helped you learn some of the pros and cons of daylight saving time! Many people share your opinion, Joshua. We'd love to hear your thoughts about what an average day without Daylight Saving would be like for you!
Thanks for sharing your opinion about the clock change, Wonder Friend! There is always a lot of discussion about this issue! Welcome, K-lee! We're glad this Wonder sparked your interest!
We're glad you learned something new, jaiden! Also check out Wonder Who Invented Time? I agree with Mary. When I was living in Arizona, which is a state that doesn't honor any time change, was great not having to worry about daylight savings. There's no reason for it. There's no having to adjust any pattern because time changed. No having to figure out about payroll because time change. Daylight saving, I know is hot wash. There's no good reason to have it; just a big inconvenience.
Hog wash, just ask hog wash. Thanks for sharing your thoughts on this Wonder topic, Linda! The time change is a debated topic for sure! We appreciate you sharing your thoughts about Daylight Savings Time, Mary! We're glad you stopped by Wonderopolis! Great question, Stanley! The Wonder tells us "the idea was first suggested in an essay by Benjamin Franklin in , and later proposed to British Parliament by Englishman William Willett Hi, Stanley!
Sometimes it may be annoying to change the clocks, but "Daylight Saving Time is most helpful to those who live farther from the equator, where daylight hours are much longer in the summer than in the winter.
SueAnn, what you mean then is that you would like 'Daylight Savings Time' to extend all year long.. When we actually need to add an hour of light, they take it away in the winter, when the natural earth orbit already takes an hour away in the winter so we actually lose 2hrs of daylight in the evening.
That is a good point, SueAnn! Safety is always important. We're glad you being cautious! Thanks for sharing your thoughts about this Wonder! Hello, Macky!
