DST in the USA: Is It Coming to an End?
Daylight Saving Time (DST) has been used in the US for more than 100 years, but it looks like it might be over soon.
19 American states have their permanent DST legislation ready for as soon as Congress says go.
The US is one of about 70 countries worldwide using Daylight Saving Time (DST), but Hawaii and most of Arizona don't use it.
When Does DST Start and End in the USA?
The change happens at 2 am local time.
Will the US Abolish Clock Changes?
On March 15, 2022, the US Senate unanimously passed the Sunshine Protection Act introduced by Florida Senator Marco Rubio. But for the bill to become law, allowing states to observe DST year-round, it must also be approved by the House of Representatives and signed into law by the President. This has not happened yet.
For now, current law only allows states to opt out of DST but not to follow it year-round.
States That Want to “Ditch the Switch”
In recent years, 19 states have passed legislation for permanent DST . More than 550 bills and resolutions have been considered at state level advocating for year-round DST, according to the National Conference of State Legislatures.
Meanwhile, nine states are considering legislation that would end the seasonal time change but keep them on year-round standard time.

Congressional approval needs to be in place for any state law to take effect.
Not All States Use DST
Hawaii observes Hawaii Standard Time (HST) all year.
Indiana decided to join the national DST regime in 2006 after abstaining from changing its clocks since 1970.
History: When Did DST Start in the USA?
In 1916, during World War I, Germany became the first country to adopt DST to save energy for the war effort. Many countries across Europe soon followed suit. In the US, “Fast Time,” as it was called then, was first introduced in 1918. The initiative was sparked by Robert Garland, a Pittsburgh industrialist who had encountered the idea in the United Kingdom.
Only seven months later, DST was repealed. But some cities, including Pittsburgh, Boston, and New York, continued to use it.
“War Time” and “Peace Time”
In 1942, at the height of World War II, President Franklin D. Roosevelt reintroduced the measure, instituting year-round Daylight Saving Time in the US. Referred to as “War Time,” DST was in force continuously from February 9, 1942 to September 30, 1945.
During this time, the US time zones were called “Eastern War Time,” “Mountain War Time,” “Central War Time,” and “Pacific War Time.” After the surrender of Japan in mid-August 1945, the time zones were relabeled “Peace Time.”
National DST Rules since 1966
From 1945 to 1966, there were no uniform rules for DST in the US. This caused widespread confusion, especially for trains, buses, and the broadcasting industry. As a result, the Uniform Time Act of 1966 was established. While granting US states the ability to opt out of DST, the law provided a framework for a nation-wide, synchronized DST schedule, starting on the last Sunday of April and ending on the last Sunday of October.
Year-Round DST in 1973
During the 1973 oil embargo, the US Congress ordered a year-round DST period lasting from January 1974 to April 1975. The rationale was to study the effects of seasonal time change on energy consumption. Following staunch opposition from the public and the realization that the measure yielded only modest energy savings, the plan was soon amended to allow for a return to standard time during the winter months.
Energy Policy Act of 2005
After the energy crisis was over in 1976, the United States DST schedule was revised several times throughout the years. From 1987 to 2006, the country observed DST for about seven months each year. The current schedule was introduced by the Energy Policy Act of 2005 and has been followed since 2007.
