Which U.S. States Don’t Follow Daylight Saving Time?

In the U.S., Daylight Saving Time (DST) begins on March 12, 2023. You know what that means? We lose an hour of sleep!!! Nooooooo!!! But, did you know there are a number of U.S. states and territories that don’t observe DST?

But first, a bit of history....

In addition to my post, “Why do we have DST anyway?”, here’s another tidbit of DST trivia. According to the U.S. Department of Transportation website,

“Federal oversight of time zones began in 1918 with the enactment of the Standard Time Act, which vested the Interstate Commerce Commission with the responsibility for establishing boundaries between the standard time zones in the continental United States. This responsibility was transferred from the Interstate Commerce Commission to DOT when Congress created DOT in 1966.

Today, the Uniform Time Act of 1966 (15 U.S.C. §§ 260-64) establishes a system of uniform Daylight Saving Time throughout the Nation and its possessions, and provides that either Congress or the Secretary of Transportation can change a time-zone boundary. “

Back to the States...


Why do you need DST when you basically live in paradise? I don’t know if that’s what Hawaii was thinking when it became the first state to ditch DST in 1968, opting out of the Uniform Time Act, but they are the most southerly state. Because that, Hawaii enjoys lots of sun, so it probably wasn’t a big advantage for it to observe DST. In fact, the last time Hawaii actually observed at all was during World War II!


Arizona is another sun-filled state that took a pass on DST in 1968. With the exception of the Navajo Nation, situated in the northeastern part of the state, Arizona doesn’t do DST. The primary reason the Navajo Nation observes DST is so that it can maintain a uniform time with other parts of the Nation that are in states that do observe DST - Utah and New Mexico.

But wait, there’s more!

A number of U.S. Territories don’t observe DST either. And yup, you guessed it – those places are pretty sunny most of the year, too. Those territories include,

  • Puerto Rico

  • The U.S. Virgin Islands

  • American Samoa

  • Guam

Recent Legislation

According to a Reuters article, there are rumblings that DST may become permanent throughout the country. The U.S. Senate unanimously passed legislation that would make daylight saving time permanent starting November of this year! It's called the Sunshine Protection Act. Even though only two U.S. states DON'T follow DST, since 2015, about 30 states have introduced legislation to end DST for reasons including preventing an increase in car crashes that occurs around the time changes and an increase in heart attacks and strokes . There's not information on whether it will actually get passed, but I had no idea DST was so controversial!
