Daylight saving time starts at 2 in the morning, the second Sunday in March when the clocks go forward one hour. NEXSTAR) — Daylight Saving Time begins Sunday, March 13, which means Americans in all but two states will adjust their clocks an hour in advance and lose some sleep. Two states in Hawaii and most of Arizona observe a permanent standard time, which means they don't change their clocks at all. Standard time is the time between November and March.
While the rest of the United States switches to daylight saving time, Arizona and Hawaii actually change time zones: Arizona changes from mountain time zone to Pacific time zone, while Hawaii shifts from five hours behind Eastern time. In the past four years, 18 states have enacted laws or resolutions to keep residents' daylight saving time throughout the year, pending congressional approval. In some cases, legislation requires neighboring states to enact similar laws. This year alone, nearly 30 states are considering daylight saving time legislation, according to NCSL.
In some cases, even if the legislation is passed, it will not be able to take effect until your neighbors make the same move. In Iowa, for example, one of its pending bills says that the state cannot leave daylight saving time until Illinois, Minnesota, Missouri, Nebraska, South Dakota, and Wisconsin enact similar legislation. To make it more complicated, Nebraska's pending law says it won't change until three of its adjacent states adopt similar laws. There is also a difference between what some states expect, according to the NCSL.
While most want to stick with daylight saving time throughout the year, which means that whatever time their clock is set from March to November becomes permanent, some want to stick with standard time. These include Colorado, Georgia, Massachusetts, Oklahoma, Vermont, and Washington. Two Years Later, Dozens of Cities Adopted Their Own Daylight Savings Time Policies. By the mid-1960s, 18 states were observing daylight saving time settings and 12 were staying in standard time.
In 1966, Congress passed the Uniform Time Act, implementing the current daylight saving time observed by 48 states, reports the Smithsonian. Department of Transportation now attributes energy conservation, accident prevention, and crime reduction to daylight saving time. Indiana uses daylight saving time. Detractors of daylight saving time say scientific studies evaluating the impact of the time policy change on daylight saving time in Indiana have identified a significant increase in energy use and electricity spending by Indiana households.
Supporters of daylight saving time and a common time zone in Indiana often claim that Indiana should adopt the Eastern United States timing system to preserve interstate business with that region. But in 1985, the Indiana General Assembly, in Concurrent Senate Resolution 6 of 1985, asked the USDOT to move five counties in southwest Indiana (Posey, Vanderburgh, Warrick, Spencer, and Gibson) from the Central Time Zone to the Eastern Time Zone. City Debate, Indiana General Assembly Passed Bill to Put All of Indiana in Central Standard Time and Ban Daylight Saving Time. Several counties in eastern Indiana (Ohio and Dearborn counties, near Cincinnati; and Floyd, Clark, and Harrison counties, near Louisville) chose to observe daylight saving time unofficially, despite Indiana statute.
Indiana enacted the statute, officially placing northwest and southwest Indiana in the Central Time Zone, in observance of daylight saving time settings, and the rest of the state in Eastern Standard Time throughout the year.
