In the vote held in the US House of Representatives, it was decided to make daylight saving time permanent and end the biannual time changes.
The law, called the Daylight Conservation Act, was passed on July 14 by a vote of 308 to 117, with bipartisan support.
The bill would permanently switch the United States to the time zone currently in place between March and November. This scheme is called permanent standard time.
Republican Scott DesJarlais, who led the vote, played a section of The Beatles' song Here Comes the Sun from his phone during the final count.
US President Donald Trump had promised to end the time changes after his second return to the White House.
After the law is passed by the House of Representatives, the Senate may soon consider this bill. Changes can also be made to the draft.
Florida Republican Rep. Vern Buchanan, who introduced the bill in January 2025, said the time changes disrupted schedules "for no good reason."
Since World War I, the United States has been turning its clocks forward during the summer months to take advantage of more daylight and save electricity.
The clocks are turned back to standard time every year in autumn.
Daylight saving time, which also helped save fuel during World War I, was unpopular with farmers and was abolished following the war.
It was reintroduced during World War II, and legislation standardizing time changes across the country was passed in 1966.
However, some states, including Hawaii and Arizona, as well as the US territory of Puerto Rico and the Virgin Islands, chose to opt out of this practice.
Trump said in a social media post in May that he would "work very hard" to pass a law regarding time changes:
"It's time for people to stop worrying about 'The Clock,' not to mention all the effort and money spent on this ridiculous bi-annual regulation. This will also be a very nice WIN for the Republican Party. Go for it!"
But critics of permanent daylight saving say it would lead to darker winter mornings and could make driving conditions more dangerous for those on the road in the wee hours.
Those who support keeping standard time instead of daylight saving time also say that more light in the morning provides health benefits, such as better sleep patterns.
According to the Pew Research Center, only about one-third of the world's countries use any form of daylight saving time, and the vast majority of them are in Europe.
In Europe, only Armenia, Azerbaijan, Belarus, Georgia, Iceland, Russia and Turkey do not use summer time.
Egypt is the only country in Africa that observes daylight saving time.
