Daylight Savings Time begins on the First Sunday in April at 2:00 AM, and ends on the last Sunday of October at 2:00 AM.\n\nStarting in 2007:\n\nDaylight Savings Time will begin at 2:00 AM on the second Sunday in March and end at 2:00 AM on the first Sunday of November.  This will provide three more weeks of DST.\n\nBe correct when using time references:\nQuite often I see a letters or messages where someone mentions a time that something is supposed to happen and adds the identifier like CDT, (Central Daylight Time). I'm sure they are trying to appear intelligent but the "Daylight" time reference is not valid in January! It doesn't exist. Same with calling out Eastern Standard Time in June. \n\nYes, I know that these references are actually accurate in Arizona and parts of Ohio.  They don't do the Daylight Savings Time thing.

(m)\n\nThe time zones of the United States are standardized by Congress and although the lines were drawn to avoid populated areas, sometimes they've been moved to avoid complication. There are nine time zones in the U.S. and its territories, they include Eastern, Central, Mountain, Pacific, Alaska, Hawaii-Aleutian, Samoa, Wake Island, and Guam.\n\nstandard time in the 7th time zone west of Greenwich, reckoned at the 105th meridian west; used in the mountain states of the United States \n\nThe Mountain Standard Time Zone (MST) is a geographic region that keeps time by subtracting seven hours from Coordinated Universal Time (UTC). In the United States, the following states are part of the Mountain Standard Time Zone: *New Mexico*Wyoming*Utah*Colorado*Montana

History of Daylight Saving in NSW\nDaylight saving operated nationally during World War I from 1 January 1917 to 25 March 1917 and during World War II for three summers, beginning on 1 January 1942. \n\nDaylight saving was introduced again in this State on 31 October 1971 after the Standard Time Act 1971 was passed by the New South Wales Parliament. \n\nA referendum held on 1 May 1976 submitted a proposal that daylight saving be adopted on a permanent basis. The ballot paper stated: \n\nAt present there is a period commonly called "daylight saving" by which time is advanced by one hour for the period commencing on the last Sunday in October in each year and ending on the first Sunday in March in the following year.

Because it is a political decision and not a scientific decision. Daylight savings time is just the government's way of making you get up an hour early.

We put the clocks forward by 1hr on Sunday 26th March 2006 and then put them back by an hour on the 29th October. It is basically to get more hours of daylight at decent times of the day!\n\nhttp://en.wikipedia.org/wiki/British_Summer_Time

No one really sets the dates. Daylight Saving Time begins for most of the United States at 2:00 a.m. on the first Sunday of April. Time reverts to standard time at 2:00 a.m. on the last Sunday of October. In the U.S., each time zone switches at a different time.\n 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.

"You might ask, isn't the changing of the clocks a federal law? The answer is that although Daylight Saving Time was established by federal law in 1986, a state or area may choose not to observe it. Other areas in the U.S. that don't observe Daylight Saving Time are Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands. In Arizona, we just don't need another hour of sunlight!"

It is sometimes suggested that Ben Franklin was the first to suggest daylight savings in a letter to the Journal of Paris. However he was putting it forward humorously.\n\nt 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. The German government introduced it during 1916 to increase productivity in World War I with the British following soon after.

"Daylight saving time (DST), often referred to as daylight 'savings' time, is a widely used system of adjusting the official local time forward, usually one hour from its official standard time for the duration of the spring and 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. (People go to bed and wake up earlier, which reduces 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)."

no, it's because of the rotation of the earth.  Clocks in the southern hemisphere go around the other direction, like your toilet ;-).\n\nIt's because the shadow on a sun dial in England goes around that direction.

Each country is in charge of determining time zones and each have passed laws to create them. They chose where they should go so that noon would basically coincide with the sun's highest point in the sky.

The History of Analog Clocks (SEE FIRST LINK BELOW) provides an explanation of the origin of the 24-hour day. The system dates back 4,000 years, to ancient Egypt and Babylon. \n\nEgyptian astronomers divided the night hours into 12 distinct sets of star patterns, which emerged over the horizon at roughly hour-long intervals. They divided the day into 12 hours to match, and because they lived near the equator, the days and nights were of roughly equal length throughout the year. \n\nThroughout the rest of the world, the 12 "hours" of the day and night were flexible depending upon the season. It wasn't until the 13th century A.D. that an Arab scientist named Abul-Hassan suggested the idea of clearly defined hours. \n\nIt's also worth noting that the number 12 is special in many cultures. For example, Egyptians counted in base 12. Dividing the day into two sets of 12 was a simple and elegant way of condensing the annual calendar into a day. \n\n*Repost*

OK, it depends on where you are at in the world. \nIf you are in New York city, subtract 5 hours from the GMT time to get local time. Chicago 6, Denver 7, Los Angeles 8; you get the picture. Of course, that changes with Daylight Savings time. \n\nTo know for sure, check your computer's time/date settings. For Windows PCs, double click the time in the lower-right corner. It'll bring up a box that'll have a "Time Zone" tab. If you go there, you should see the something like "GMT -xx:00", where the xx is a number of hours. Subtract that number (or add it, if the number is +xx:00), and that's the sent time.

Benjamin Franklin  was among the first Americans to discuss the idea of Daylight Saving Time. In fact, he proposed the idea while serving as U.S. minister to France as a way of conserving the cost of lighting for shops. The purpose has been to essentially utilize more of the daylight hours in spring and summer for daytime activities. Simply put, the Sun is up longer in the sky (rises earlier and sets later) in summer. Clocks and common mechanical timepieces keep what's called civil time, which roughly corresponds to the passage of a fictitious "average" Sun through our sky. This is necessary since the Sun does not rise and set on a regular basis, but changes by as much as 15 minutes throughout the course of the year.\n\nDaylight Saving Time was generally adopted by countries around World War I, but President Wilson repealed the United States' mandatory daylight savings law on March 31, 1918. During World War II, Daylight Savings Time was reestablished by law on a year-round basis, and later seen as a fuel saving measure during the Arab Oil Embargo crisis of 1973-74. In late 1974, standard time was brought back. During World War II, the U.S. and some other countries implemented "double" daylight savings time consisting of a two hour shift.

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.
