Daylight saving time in the United states - Wikipedia Daylight saving time in the United states Ohio Clock in the U.S. Capitol being turned forward for the country 's first daylight saving time in 1918 Daylight saving time in the United States is the practice of setting the clock forward by one hour during the warmer part of the year, so that evenings have more daylight and mornings have less. Most areas of the United States observe daylight saving time ( DST ), the exceptions being Arizona ( except for the Navajo, who do observe daylight saving time on tribal lands ), Hawaii, and the overseas territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. The Uniform Time Act of 1966 established the system of uniform Daylight Saving Time throughout the US. In the U.S., daylight saving time starts on the second Sunday in March and ends on the first Sunday in November, with the time changes taking place at 2 : 00 a.m. local time. With a mnemonic word play referring to seasons, clocks `` spring forward, fall back '' -- that is, in springtime the clocks are moved forward from 2 : 00 a.m. to 3 : 00 a.m. and in fall they are moved back from 2 : 00 a.m. to 1 : 00 a.m. Daylight saving time lasts for a total of 34 weeks ( 238 days ) every year, about 65 % of the entire year.

His 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. Franklin 's suggestion seems to have been more of a joke than a real proposal, and nothing came of it. 1916 -- 1966 : early, inconsistent use During World War I, in an effort to conserve fuel, Germany began observing DST on May 1, 1916. The rest of Europe soon followed. The plan was not adopted in the United States until the Standard Time Act of March 19, 1918, which confirmed the existing standard time zone system and set summer DST to begin on March 31, 1918 ( reverting October 27 ). The idea was unpopular and Congress abolished DST after the war, overriding President Woodrow Wilson 's veto. DST became a local option and was observed in some states until World War II, when President Franklin Roosevelt instituted year - round DST, called `` War Time '', on February 9, 1942. It lasted until the last Sunday ( the 30th ) in September 1945. After 1945 many states and cities east of the Mississippi River ( and mostly north of the Ohio and Potomac rivers ) adopted summer DST. From 1945 to 1966 there was no federal law on daylight saving time, so localities could choose when it began and ended or drop it entirely. As of 1954, only California and Nevada had statewide DST west of the Mississippi, and only a few cities between Nevada and St. Louis. In the 1964 Official Railway Guide, 21 of the 48 contiguous states had no DST anywhere. 1966 -- 1972 : federal standard established 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. 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 2014, the following states and territories are not observing DST : Arizona, Hawaii, American Samoa, Puerto Rico, and the Virgin Islands. 1973 -- 1975 : year - round Experiment During the 1973 oil embargo by the Organization of Arab Petroleum Exporting Countries ( OAPEC ), in an effort to conserve fuel, Congress enacted a trial period of year - round DST ( P.L. 93 - 182 ), beginning January 6, 1974, and ending April 27, 1975. 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. The act was amended in October 1974 ( P.L. 93 - 434 ) to return to standard time for the period beginning October 27, 1974, and ending February 23, 1975, when DST resumed. When the trial ended in 1975, the country returned to observing summer DST ( with the aforementioned exceptions ). 1975 -- 1986 : extension of daylight saving time The DOT, evaluating the plan of extending DST into March, reported in 1975 that `` modest overall benefits might be realized by a shift from the historic six - month DST ( May through October ) in areas of energy conservation, overall traffic safety and reduced violent crime. '' However, DOT also reported that these benefits were minimal and difficult to distinguish from seasonal variations and fluctuations in energy prices. Congress then asked the National Bureau of Standards ( NBS, today NIST ) to evaluate the DOT report. Its report, `` Review and Technical Evaluation of the DOT Daylight Saving Time Study '' ( April 1976 ), found no significant energy savings or differences in traffic fatalities. It did find statistically significant evidence of increased fatalities among school - age children in the mornings during the four - month period January -- April 1974 as compared with the same period ( non-DST ) of 1973. NBS stated that it was impossible to determine, what, if any, of this increase was due to DST. When this data was compared between 1973 and 1974 for the months of March and April, no significant difference was found in fatalities among school - age children in the mornings. In 1986 Congress enacted P.L. 99 - 359, amending the Uniform Time Act by changing the beginning of DST to the first Sunday in April and having the end remain the last Sunday in October. These start and end dates were in effect from 1987 to 2006. The time was adjusted at 2 : 00 a.m. local time. 2005 -- 2009 : second extension By the Energy Policy Act of 2005, daylight saving time ( DST ) was extended in the United States beginning in 2007. As from that year, DST begins on the second Sunday of March and ends on the first Sunday of November. In years when April 1 falls on Monday through Wednesday, these changes result in a DST period that is five weeks longer ; in all other years the DST period is instead four weeks longer. In 2008 daylight saving time ended at 2 : 00 a.m. DST ( 0200 ) ( 1 : 00 a.m. ST ) on Sunday, November 2, and in 2009 it began at 2 : 00 a.m. ( 3 : 00 a.m. DST ) on Sunday, March 8. Under Section 110 of the Act, the U.S. Department of Energy was required to study the impact of the 2007 DST extension no later than nine months after the change took effect. The report, released in October 2008, reported a nationwide electricity savings of 0.03 % for the year of 2007. An October 2008 study conducted by the University of California at Santa Barbara for the National Bureau of Economic Research found that the 2006 DST adoption in Indiana increased energy consumption in Indiana by an average of 1 %. Although consumption for lighting dropped as a result of the DST adoption, consumption for heating and cooling increased by 2 % to 4 %. The cost to the average Indiana household of the DST adoption was determined to be $3.29 per year, for an aggregate cost of $1.7 million to $5.5 million per year. The United States Chamber of Commerce has praised the extension of daylight saving under the 2005 law, which increased the amount of shopping and commerce from after work in evenings. In the golf industry, the group has noted exceptional increase in revenue of `` $200 million in additional sales of golf clubs and greens fees ''. The extension of daylight saving has also had a notable impact on Halloween and candy sales. Wyoming Senator Michael Enzi and Michigan Representative Fred Upton advocated the extension from October into November especially to allow children to go trick - or - treating in more daylight. In some areas, the extension of daylight saving time in March and November has pushed back sunrise to as late as 8 : 30 am. Procedure for modifications Changing an area 's time zone 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 commerce is defined broadly to consider such circumstances as the shipment of goods within the community ; the origin of television and radio broadcasts ; the areas where most residents work, attend school, worship, or receive health care ; the location of airports, railway, and bus stations ; and the major elements of the community 's economy. After receiving a request for altering a time zone, DOT determines whether it meets the requirement of minimum statutory criteria before issuing a notice of proposed rulemaking, soliciting public comment and scheduling a public hearing. Usually the hearing is held in the area requesting the change so that all affected parties can be represented. After the close of the comment period, the comments are reviewed and appropriate final action taken. If the Secretary agrees that the statutory requirement has been met, the change is instituted, usually at the next changeover to or from DST. Moving an area on or off DST Under the Uniform Time Act, moving an area on or off DST is accomplished through legal action at the state level. Some states require legislation while others require executive action such as a governor 's executive order. Information on procedures required in a specific state may be obtained from that state 's legislature or governor 's office. Although it may exempt itself, if a state decides to observe DST, the dates of observance must comply with federal legislation. Local DST observance Alaska This section needs to be updated. Please update this article to reflect recent events or newly available information. ( November 2017 ) 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 occurring as late as 2 : 10 p.m. in the population centers of Anchorage and Fairbanks, and as late as 3 : 23 p.m. in places such as Nome. In Fairbanks, for example, sunset occurs well after civil midnight in the summer. Others argue that ending daylight saving time will place Alaska as much as five hours from Eastern Daylight Time, making coordination of travel and phone conversations more difficult. In March 2015 the Alaska Senate passed a bill, introduced by state senator Anna MacKinnon, to end daylight saving time. The Alaska House formed a sub-committee that was due to look into the issue during the 2016 legislative session. Arizona Arizona observed DST in 1967 under the Uniform Time Act because the state legislature did not enact an exemption statute that year. In March 1968 the DST exemption statute was enacted and the state of Arizona has not observed DST since 1967. This is in large part due to an effort to conserve energy. Phoenix and Tucson are among the hottest U.S. metropolitan areas during the summer, resulting in more power usage from air conditioning units and evaporative coolers in homes and businesses. An extra hour of sunlight while people are active would cause people to run their cooling systems longer, thereby using more energy. Reservations in Arizona The Navajo Indian Reservation extends into Utah and New Mexico and does observe daylight saving time. The Hopi Reservation is entirely within the state of Arizona and is an enclave within the Navajo Indian Reservation, but does not observe DST. California California voters passed Proposition 12 in 1949, approving DST in the state. In February 2017, California Assembly member Kansen Chu introduced A.B. 807, proposing to enable the legislature to eliminate DST in the state, or, if federal law allows, to adopt DST for the entire year. Chu then shelved his bill in September 2017. He then reintroduced A.B. 807 in 2018 ; it was approved by the California State Legislature, signed by Governor Jerry Brown, and placed on the November 2018 state ballot. If approved by Congress, California would be allowed to remain on DST all year. Florida Daylight saving time is less useful in Florida compared to other states because its southern location leads to less variations in day length between winter and summer. Without DST, Miami, for instance, would experience similar sunrise and sunset times throughout the year to cities including 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 ( i.e. placing the portion of the state in the Eastern time zone on standard time, while leaving the portion in the Central time zone on DST, so that the whole state had a common time ). There are currently no states that keep daylight saving time year round. On March 6, 2018, the Florida Senate approved the `` Sunshine Protection Act '' which would put Florida on permanent Daylight Saving Time year round, and Governor Rick Scott signed it March 23. Congress would need to amend the existing 1966 federal law to allow the change. Hawaii Hawaii has never observed daylight saving time under the Uniform Time Act, having opted out of the Act 's provisions in 1967. Because of Hawaii 's tropical latitude, there is not a large variation in daylight length between winter and summer. Advancing the clock to UTC − 9 ( DST ) in Hawaii would make sunrise times close to 7 : 00 a.m. even in June. Most of the inhabited islands are located close to the west end of the Hawaii - Aleutian time zone, but Oahu, Kauai, and Niihau are located more than 7 degrees west of the Hawaii - Aleutian time zone 's meridian and should, theoretically, be located in the next time zone to the west. ( Until about 1946 Hawaiian standard time was based on longitude 157.5 degrees west rather than 150 degrees. ) On April 26, 1933, the Territorial Legislature enacted a bill placing Hawaii on daylight saving time from the last Sunday in April ( April 30 in that year ) to the last Sunday in September, but the law was repealed three weeks later on May 21, 1933. During World War II between February 9, 1942 and September 30, 1945, Hawaiian Standard Time was advanced one hour to so - called `` Hawaiian War Time, '' effectively placing the territory on year - round daylight saving time. In both cases where DST was used, Hawaii used UTC − 9 : 30 during DST as standard time was 30 minutes behind. Indiana See also : Time in Indiana From 1970 until 2006, most of Indiana in the Eastern Time Zone did not observe daylight saving time, but the entire state started to do so in April 2006 after eight counties in western Indiana were shifted from the Central Time Zone to the Eastern Time Zone. One goal for observing DST was to get more Indiana counties observing the same time zone ; formerly, 77 counties observed EST, 5 observed EST / EDT ( the EDT usage being unofficial only ), and 10 observed CST / CDT. As of 2016, Indiana has 12 counties observing Central Daylight Time while the remaining 80 counties observe Eastern Daylight Time. Those counties observing CST are in two groups : one near or in the Chicago metropolitan area, and the other around Evansville in the southwest corner of the state. Michigan In 1967, the Michigan Legislature adopted a statute, Act 6 of the Public Acts of 1967, exempting the state from the observance of DST. The exemption statute was suspended on June 14, 1967, however, when the referendum was invoked. From June 14, 1967 until the last Sunday in October 1967, Michigan observed DST, and did so in 1968 as well. The exemption statute was submitted to the voters at the General Election held in November 1968, and, in a close vote, the exemption statute was sustained. As a result, Michigan did not observe DST in 1969, 1970, 1971, or 1972. ( Radio station CKLW in Windsor, Ontario, just across the river from Detroit, was popular on both sides of the border and would often give both times on the air, e.g. `` It 's 4 : 30 in Detroit and 5 : 30 in Windsor ! '' ) In November 1972, an initiative measure, repealing the exemption statute, was approved by the voters. Michigan again observed DST in 1973, and has continued to do so since then. The vast majority of Michigan is in the Eastern Time Zone. Only the Upper Peninsula counties that border Wisconsin ( Gogebic, Iron, Dickinson, and Menominee ) are in the Central Time Zone. Nevada In 2015, the Nevada Senate passed Nevada Assembly Joint Resolution 4, which urged Congress to enact legislation allowing individual states to establish daylight saving time as the standard time in their respective states throughout the calendar year. This would mean that Nevada is on the same time as Arizona all year, but would be an hour ahead of California in the winter. The United States Congress has not yet enacted any enabling legislation in this regard. Washington In 2015, Rep. Elizabeth Scott ( R - Monroe ) filed a House bill to end DST in Washington, and a companion bill was filed in the Senate. She told a House committee that the semiannual time switches are not only inconvenient but lead to health problems and accidents due to lost sleep. She added that the bill to drop daylight saving time would reduce heart attacks, car wrecks, and work accidents found to increase with the sleep - schedule disruptions. A different Senate Bill would petition the federal government for year - round DST. The bills were defeated. Other U.S. locations All U.S. insular territories with civilian government ( American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and the Virgin Islands ) lie in the tropics and do not observe DST. While neighboring Samoa began observing DST in September 2010, the smaller American Samoa can not legally follow because of the DST observation period mandated by the Uniform Time Act. This period is actually wintertime in this Southern Hemisphere territory. Time zones Many computer operating systems ( such as Microsoft Windows, Linux, UNIX, and macOS ) and programming languages ( such as Java, perl, and most shell languages ) allow a local time zone setting in the format of ( standard time zone abbreviation ) ( UTC hour difference ) ( daylight saving time zone abbreviation ). This allows programs and programming languages that must do calculations based on local time to more easily calculate differences between local time and UTC, as well as knowing whether calculations should be changed during daylight saving time. For example, a time zone setting of EST5EDT indicates that local time on the computer is 5 hours behind UTC and should be adjusted for daylight saving time.

Question: when does california go to daylight savings time
Answer: the second Sunday in March
