After a long winter of short days, it’s finally time to move forward.
Watches across the US will jump from 1:59am to 3am on Sundays.
Here are some things you need to know about saving daylight savings and why you change your watch twice a year in the US:
How long does daylight saving time last?
Daylight saving time continues from Sunday until November 2nd. Standard time will be valid from November 3rd to Sunday, 2024.
The changes in the spring clock are different from those in autumn. Unlike autumn, it buys extra time and loses an hour in spring when the clock recedes.
However, it changes to longer days and brighter evenings as the spring and summer months begin. It will be active until the clock is returned to standard time. This will come into effect on November 2nd, as it is ready for winter and will mark a shorter day period.
Why change the clock?
The United States has been saving daylight savings since 1918 along with passing the Standard Time Act, according to the US Department of Astronomical Applications. It was an effort to push the sunset for an hour to extend the summer sunlight.
Daylight savings time was not fully accepted at first. It was quickly discontinued in 1919, and changes to the clock became a local issue. This practice was officially revived in the early years of World War II and was observed from 1942 to 45.
Daylight saving time was varied from state to state through the passage of a uniform time law until 1966. This standardized daylight savings time dates, but allowed states and regions to opt out of practice if they didn’t want to participate.
Since the legislation was passed, the standardized date has been changed over the years, according to the department.
However, the date has remained the same since 2007. Since then, daylight saving time has started on the second Sunday of March and ended on the first Sunday of November.
Are there any states that do not observe changes in time?
yes. Most residents in Hawaii and Arizona do not lose an hour of sleep on Sunday nights. According to the Astronomy Department, the two states do not observe daylight saving time and do not change clocks twice a year.
Is someone trying to change your practice?
The US Senate will continue to save daylight savings in March 2022, and will guide you through an era of clock change. Most of Hawaii and Arizona will continue to observe standard times for the annual round.
But the bill was stagnant in the House of Representatives, and the US continues to flip its clock twice a year until new laws are passed in the House and Senate and signed by a likely president to sit down.
President Donald Trump worked on practice this week when he asked reporters to “remove” daylight saving time.
“People want to slow down more light, but some people want to get brighter sooner, because they don’t want their kids to school in the dark,” he called the issue “50-50.”
“But a lot of people like it in one way. A lot of people like it. It’s very even,” he said. “And usually I find that is true, what else should we do?”
Shortly after winning last year’s election, Trump said he and Republicans would be inconvenient and expensive to try to “eliminate” daylight saving time. It was unclear at the time whether he was referring to saving daylight savings or making it permanent.
Almost every US state is considering the law to avoid changing clocks and avoid saving either standard or daylight savings all year round.
Over the past six years, 20 states have passed bills or resolutions to codify daylight savings time, according to the state legislature’s national meeting. However, federal law does not currently allow daylight savings time all year round, so these states are in a retention pattern until Congress passes the bill to make changes.
Is the US the only country that changes clocks?
No, many other countries have been observing several versions of “summer time” whether it is daylight saving time or its own version. But not everything will do on the same schedule as in the US.
In the Southern Hemisphere, for example, seasons are exchanged, so according to the astronomical application department, the start and end dates of “summer time” are reversed from ours.
What do health experts say?
Some studies suggest that using daylight savings time can reduce the number of road accidents and the amount of crime, but many experts are opposed to it on longer days a year.
According to some sleep experts, the sun should reach the highest point in the sky at noon, or the solar time that occurs at a standard time.
A survey from June 2022 found that people who had no time in close alignment with the sun had a road fatality rate 22% higher than those who live within 30 minutes of the sun’s time.
Corrected (March 8, 2025, 3:26pm ET): Previous versions of this article incorrectly stated how often the clock changes. It’s twice a year, not every six months.
