Why is daylight savings time necessary? Why can't they just leave the time alone?

Its to make more evening time ( time before lights on ) available to office workers. In UK they even had double-DST during wwII

We don't have daylight savings time here

In short it is called as Daylight Saving Time (DST)\n\nDST is mostly used in temperate regions, due to the considerable variation in the amount of \ndaylight versus darkness across the seasons in those regions.\n\nDaylight saving time (DST), also known as summer time, is a conventional local time adopted by many states of the world on a seasonal basis. Most commonly DST is obtained by adjusting the official local time forward, by one hour, for the spring, summer, and early autumn periods.

I personally don't care which time period we stick with.....just PICK ONE and stick with it!! Having to change all those clocks twice a year in ridiculous.

In Australia only some states still have daylight savings. Queensland got rid of it for a number of reasons. One being that the farmers complained it was upsetting the cows timetable.

Daylight savings time was invented by Benjamin Franklin as a way for people to have more productive days. In the summer we "borrow" an hour from the morning and stick it onto the end of the day so that the long summer days are even longer.

Daylight saving time (DST), also known as summer time and sometimes referred to (some think erroneously - see later) as daylight savings time, is a widely used system of adjusting the official local time forward, usually by one hour, from its official standard time for the summer months. This is intended to provide a better match between the hours of daylight and the active hours of work and school. The "saved" daylight is spent on evening activities which get more daylight, rather than being "wasted" while people sleep past dawn.\n\nDST is most commonly used in temperate regions, due to the considerable variation in the amount of daylight versus darkness across the seasons in those regions.\n\nGovernments often tout it as an energy conservation measure, on the grounds that it allows more effective use of natural sunlight resource in summer time. Since there is less darkness in the "waking day", there is less use of electric lights. Some opponents reject this argument (see below, Criticism).\n\nEuropeans commonly refer to the system as summer time: Irish Summer Time, British Summer Time, and European Summer Time. This is reflected in the time zones names as well, e.g., Central European Time (CET) becomes Central European Summer Time (CEST).\n\nThe word "summer" in this context includes most of spring after the spring equinox and nearly all of autumn (April through October). Likewise, the word "winter" here includes part of autumn and a few weeks in spring (November through March). This varies by time zone, of course, and can change over time as well.

They're made so the clock corresponds to daylight.  It was convenient to break the world into one-hour zones, which would give you 24.  The zones are determined by state and national boundaries and population concentrations, so they aren't perfectly straight north-south lines.  But the general result is that the sun is always about highest at noon, no matter where you are.  That only leaves the question of how we determine when we move from one day to the next.  That would be the international date line, running down through the Pacific ocean and carefully avoiding almost everything.

Originally, each town set its own local time and 12:00 noon was when the sun was highest in the sky. Thus the time in each town was different. When trains started running, this became annoying in trying to develop schedules. Time zones were created to standardize time over large areas.

Why, aren't they two of the many regions that remain on "standard time" year-round? \n\nIt's controversial, but some people say this approach is the way of the future.

I dont know.  How did the english get the world to go along with it?  Also why not have 12 hours of light and 12 hours of dark.  Instead they do 6am is sunrise.  Why not 1am sunrise and 1pm sunset.

nothing to do with daylight savings. Daylight savings is a human invention, not a natural phenomenon.\n\n...because leap seconds are not being added to compensate for the Earth's rotation slowing down.\n\nThe amount of time it takes for the earth to revolve around the sun is 365.2425 days.\n\nEven that is an approximation, the decimal digits can keep going on.\n\nSo initially, the calendar was divided evenly in 365 days. But about every 4 years, you'd be off 1 day. A century later, you've drifted off by a whole month!\n\nSo, leap years came into effect. Febuary has another day every 4 years. \n\nBut now you've approximated a year to 365.25 days, when in reality, its 365.2425 days.\n\nEvery century, you'll be off 1 day.\n\nSo that's where the next rule comes into play: "If the year is divisible by 4, but not by 100, its a leap year."\n\nNow we've approximated it to 365.2425, but because its always going to be an approximation, our calendar days are always slipping. All because the earth doesn't take exactly 365 days to go around the sun.\n\nThis is why leap seconds are added, and not to account for the slowdown of the earth's rotation.\n\nAs to why days are divided in exactly 24 hours, I'm not sure. But I would think the time difference is WAY less than 20 minutes, or we'd notice that soon enough, its dark at noon! :)  Time was divided a long time ago, and a simple system was sought for keeping track of it, so the minuts/hour/year thing is a nice division thats easy to do math with. The lost time, if its accounted for by leap years and such, could be easier to manage.\n\nFirst, I never said the earth is not slowing down. I said its not why leap seconds exist. And ok, I can entertain my explanation may be wrong, but that's no reason for your condescending tone, Jolly Roger. But look, your link brings me to a christian science evanglism site, where is the evidence that my answer is incorrect? \n\nYou haven't bothered to explain his original question. If leapseconds account for the slowdown of the earth's rotation, why are there leap seconds and not leap milliseconds?\n\nIf you want to append to your answer, at least try to do so while respecting the other users on this site, and not insult their intelligence.\n\nThis has piqued my curiosity, if there's anyone out there that has a source that says my explanation is incorrect, I mean an actual science website, you know, one that steers clear of religion, please let me know.

I wish I wasn't! I hate DST. There doesn't seem to be a good enough reason to go through all that hassle.

This is reflected in the time zones names as well, e.g., Central European Time (CET) becomes Central European Summer Time (CEST).\n\nIt is sometimes asserted that DST was first proposed by Benjamin Franklin in a letter to the editors of the Journal of Paris. However, the article was humorous; Franklin was not proposing DST, but rather that people should get up and go to bed earlier.\n\nIt was first seriously proposed by William Willett in the "Waste of Daylight", published in 1907, but he was unable to get the British government to adopt it, despite considerable lobbying.\n\nThe idea of DST was first put into practice by the German government during the First World War, between April 30 and October 1, 1916. Shortly afterward, the United Kingdom followed suit, first adopting it between May 21 and October 1, 1916. On March 19, 1918, the U.S. Congress established several time zones (which had been in use by railroads and most cities since 1883) and made DST official, effective March 31, for the remainder of World War I. It was observed for seven months in 1918 and 1919. The law, however, proved so unpopular (mostly because people rose and went to bed earlier than in current times) that it was later repealed.\n\nDST is generally a temperate zone practice; day lengths in the tropics do not vary enough to justify DST. Hawaii and Arizona are the only U.S. states that do not observe DST.\n\nThe amount of the time shift varies, but one hour is the most common. The dates of the beginning and ending of DST also vary by country. With a few exceptions, switchovers between standard time and DST generally occur in the early hours of a Sunday morning, because doing so then causes less disruption than a change on a weekday would.\n\nDST commonly begins in the northern hemisphere on the last Sunday in March or the first Sunday in April, and ends on the last Sunday in October. However, beginning in 2007, the United States will begin observing DST from the second Sunday in March until the first Sunday in November. If no energy savings can be shown from the extension after the U.S. Department of Energy completes a study of impact of the change, Congress may revert back to the schedule set in 1986 under Section 110 of the Energy Policy Act of 2005. Since 2002, the European Union has fixed the last Sunday in March and the last Sunday in October as start and end dates (European Summer Time).\n\nIn the southern hemisphere, the beginning and ending dates are switched; therefore, the time difference between the United Kingdom and Chile may be 4, 5 or 6 hours, depending on the time of year.\n\nThe U.S. federal Uniform Time Act of 1966 mandated that DST begin nationwide on the last Sunday in April and end on the last Sunday in October, effective in 1967. Any state that wanted to be exempt from DST could do so by passing a state law, provided that it exempted the entire state. The law was amended in 1972 to permit states that straddle a time zone boundary to exempt the entire area of the state lying in one time zone. On July 8, 1986, President Ronald Reagan signed the Federal Fire Prevention and Control Act of 1986 into law, which amended the starting date of DST to the first Sunday in April, to take effect the following year.\n\nIn response to the 1973 energy crisis, DST in the United States began earlier in both 1974 and 1975, commencing on the first Sunday in January (January 6) in the former y

we do it because it saves energy.\nit causes it to be daylight longer, when we're not sleeping.\nin fact, back in the late 70s, when there was an oil shortage, they made daylight savings time go all year.\nit's not for farmers.\nthey're smart enough to work when it's light.\nit's for the rest of us, who don't seem to be.

I've never found that, but I have found that at Daylight Savings Time, it will change.  It doesn't even sound plausible, but it always works like that. I'm really not sure why, but my mom and best friend have the same problem.  Who knows.
