What was the Uniform Time Act of 1966?
By 1962, the transportation industry found the lack of consistency confusing enough to push for federal regulation. The result was the Uniform Time Act of 1966 (P.L. 89-387). Beginning in 1967, the act mandated standard time within the established time zones and provided for advanced time: Clocks would be advanced one hour beginning at 2:00 a.m. on the last Sunday in April and turned back one hour at 2:00 a.m. on the last Sunday in October. States were allowed to exempt themselves from DST as long as the entire state did so. If a state chose to observe DST, the time changes were required to begin and end on the established dates. The act also required states that used daylight saving time in 1966 to start it on the last Sunday in April and end it on the last Sunday in October. In 1967, Arizona and Michigan became the first states to exempt themselves from DST (Michigan would begin observing DST in 1972). In 1972, the act was amended (P.L. 92-267), allowing those states split between time zones to exempt either the entire state or that part of the state lying within a different time zone. The newly created Department of Transportation (DOT) was given power to enforce the law. As of 2020#N#[update]#N#, the following states and territories are not observing DST: Arizona, Hawaii, American Samoa, Guam, The Northern Mariana Islands, Puerto Rico, and the Virgin Islands.
Why is daylight saving time not used in Florida?
Daylight saving time is less useful in Florida than in other states because its southern location leads to less variation in day length between winter and summer. Without DST, Miami, for instance, would experience sunrise and sunset times throughout the year similar to cities such as Honolulu or Hong Kong, which have both abandoned DST for decades. There is opposition to DST in Florida. State senator Bill Posey introduced a bill in March 2008 to abolish daylight time in the state and keep Florida on year-round standard time. Because Florida straddles two time zones, the Florida legislature has the option of returning all or part of the state to standard time along time zone boundaries.

The trial was hotly debated. Those in favor pointed to increased daylight hours in the summer evening: more time for recreation, reduced lighting and heating demands, reduced crime, and reduced automobile accidents. The opposition was concerned about children leaving for school in the dark and the construction industry was concerned about morning accidents. The act was amended in October 1974 (P.L. 93-434) to return to standard time for four months, beginning October 27, 1974, and ending February 23, 1975, when DST resumed. When the trial ended in October 1975, the country returned to observing summer DST (with the aforementioned exceptions).

Who invented daylight saving time?
The earliest concept of Daylight Saving Time is commonly associated with Benjamin Franklin who—while in Paris in 1784 as an American delegate—penned an essay on the thrift of artificial versus natural lighting entitled An Economic Project.
Why is daylight saving time called summer time?

What is daylight savings time?
Daylight saving time ( DST ), also known as daylight savings time or daylight time (the United States and Canada ), and summer time ( United Kingdom, European Union, and some others), is the practice of advancing clocks (typically by one hour) during warmer months so that darkness falls at a later clock time.
How did the ancient civilizations adjust their daily schedules?
Ancient civilizations adjusted daily schedules to the sun more flexibly than DST does, often dividing daylight into 12 hours regardless of daytime, so that each daylight hour became progressively longer during spring and shorter during autumn. For example, the Romans kept time with water clocks that had different scales for different months of the year; at Rome's latitude, the third hour from sunrise ( hora tertia) started at 09:02 solar time and lasted 44 minutes at the winter solstice, but at the summer solstice it started at 06:58 and lasted 75 minutes. From the 14th century onwards, equal-length civil hours supplanted unequal ones, so civil time no longer varied by season. Unequal hours are still used in a few traditional settings, such as some monasteries of Mount Athos and all Jewish ceremonies.
Why is daylight saving time pushed an hour later?
Since daylight saving time creates the illusion of the sun rising and setting one hour later on the clock, but does not add any additional daylight , the already later sunrise times under standard time are pushed an hour later on the clock with daylight saving time. Late sunrise times can become unpopular in the winter months which essentially forces workers and schoolchildren to begin the day in darkness. In 1974 following the enactment of the Emergency Daylight Saving Time Act in the United States, there were complaints of children going to school in the dark and working people commuting and starting their work day in pitch darkness during the winter months. The complaints led to the repeal of the act in October 1974 when standard time was restored until February 23, 1975. In 1976, the United States returned to the schedule set under the Uniform Time Act of 1966. In 1971, year-round daylight time in the United Kingdom was abandoned after a 3-year experiment because of complaints about winter sunrise times. The same complaints also led to Russia abandoning DST and instituting standard time year round in 2014.
How many hours is DST?
The typical implementation of DST is to set clocks forward by one hour in the spring (" spring forward") and set clocks back by one hour in autumn (" fall back") to return to standard time. As a result, there is one 23-hour day in late winter or early spring and one 25-hour day in the autumn . Daylight saving time regions:
When do clocks turn back?
When DST observation begins, clocks are advanced by one hour (as if to skip one hour) during the very early morning. When DST observation ends and standard time observation resumes, clocks are turned back one hour (as if to repeat one hour) during the very early morning.
What is the clock called in winter?
In most countries that observe seasonal daylight saving time, the clock observed in winter is legally named "standard time" in accordance with the standardization of time zones to agree with the local mean time near the center of each region.

Overview
History of DST in the United States
Benjamin Franklin proposed a form of daylight time in 1784. Writing as an anonymous "subscriber", his tongue-in-cheek essay, "An Economical Project for Diminishing the Cost of Light", written to the editor of The Journal of Paris, observed that Parisians could save on candles by getting out of bed earlier in the morning, making use of the natural morning light instead. By his calculatio…
Procedure for modifications
Under the Standard Time Act of 1918, as amended by the Uniform Time Act of 1966, moving a state or an area within a state from one time zone to another requires a regulation issued by DOT. The governor or state legislature may initiate a request for the state or any part of the state; the highest elected officials in the county may make a request for that county. The standard in the statute for such decisions is the convenience of commerce in that area. The convenience of co…
Local DST observance
Alaska observes DST. Due to its high latitude, Alaska has nearly round-the-clock daylight during summer, and DST is seen by some Alaskans as unnecessary and a nuisance. Another issue is that the Alaskan mainland's single time zone, which approximates solar time in the capital, Juneau, leads to a large disparity between civil time and solar time for much of the state, with solar noon occurrin…
