Daylight Saving Time | State Legislation

12/30/2020

Sun dial in City Park, Denver, CO.

March to November

The daylight saving time (DST) period in the U.S. begins each year on the second Sunday in March when clocks are set forward by one hour. They are turned back again to standard time on the first Sunday in November as DST ends.

State Legislation: Daylight Saving Time (DST) 2019 and 2020 (Carryover, Introduced and Enacted)

In the last three years, 13 states have enacted legislation to provide for year-round daylight saving time, if Congress were to allow such a change, and in some cases if surrounding states enact the same legislation. Full-time DST is not currently allowed by federal law and would require an act of Congress to make a change.

The 13 states are: 

  • In 2020: Georgia, Idaho, Louisiana, South CarolinaUtah and Wyoming.
  • In 2019: Arkansas, Delaware, Maine, Oregon, Tennessee and Washington
  • In 2018: Florida (California voters authorized such a change in 2018, but legislative action is still pending).

Legislation in 2020

  • In 2020, at least 32 states have considered 86 pieces of legislation, and six states—Georgia, Idaho, Louisiana, South Carolina, Utah and Wyoming—have enacted legislation. All of these would establish DST as the official time year-round, subject to an authorizing federal law and in some cases contingent on surrounding states enacting the same legislation.

Six states—Illinois, Massachusetts, Michigan, New Jersey, New York and Ohio—are currently considering 20 pieces of legislation related to Daylight Saving Time (DST), including “carryover” bills from 2019 and 2020 introductions. As of December 2020, 32 states have considered 86 pieces of legislation, and six states—Georgia, Idaho, Louisiana, South Carolina, Utah and Wyoming—enacted new laws. Additionally, at least three states—Arkansas, South Carolina and Texas—have pre-filed legislation that will be introduced in 2021 related to DST.

Background

The U.S. had daylight saving time (DST) as early as 1918, with the current federal policy being enacted in 1966, as the Uniform Time Act. Several changes occurred along the way, mostly changing the dates of starting and ceasing DST. The current enactment was part of the Energy Policy Act of 2005. The U.S. Department of Transportation is the federal agency responsible for overseeing DST and the country’s time zones. All states but Hawaii and Arizona (except for the Navajo Nation) observe DST. The territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands also do not observe DST. Federal law allows a state to exempt itself from observing daylight saving time, upon action by the state legislature to do so but does not allow the permanent observance of DST.

The policy debate has many angles. Originally enacted as a way to save energy by giving more daylight in the evening hours, some studies have called into question the degree of energy savings. Other studies have shown negative impacts on people’s health and circadian rhythms because of time changes as well as a higher number of car crashes and workplace injuries in the days after a time change. The U.S. Department of Transportation website states that DST saves energy, saves lives and prevents traffic injuries and it reduces crime since people tend to be out and about more in daylight hours as opposed to the night when most crimes are committed.

It would seem that a primary complaint of those seeking a change from the current situation is the act of time switching itself, and the problems that it creates. Opinions are mixed on the benefits of daylight time versus standard time, but the actual March and November time changes are almost universally reviled because of all the accompanying adjustments that all of us make, like coming home from work in the dark and the slower-than-expected resetting of our internal time clocks. State legislatures have been active in bill introductions over the last several years that would place the state on either side of the issue, either staying on standard time permanently or making permanent day saving time. Since 2015, more than 200 bills and resolutions have been introduced in virtually every state to either stay on standard time or convert to full-time DST.

Until 2018, none of the hundreds of bills under consideration passed. However, in 2018, California and Florida voted to make DST permanent and, in 2019, an additional six states passed legislation to place the state on year-round DST, if authorized by Congress. Utah passed a resolution urging Congress to authorize year-round DST in a resolution but did not commit the state to do so.
