The U.S. House of Representatives passed the Sunshine Protection Act, a bill that would establish permanent daylight saving time across the United States. The measure seeks to end the biannual clock changes, effectively moving one hour of daylight from the morning to the evening year-round. President-elect Donald Trump indicated his support for the legislation on social media, stating he would sign it into law if it reaches his desk.
The bill now moves to the Senate, where its future remains uncertain. Senate Majority Leader John Thune noted that while there is member interest, there is no consensus within the chamber. Thune cited concerns regarding state optionality and geographic differences, noting that representatives from northern states often oppose the change due to late winter sunrises. A group of bipartisan senators on the Senate Commerce Committee has previously voted against similar efforts.
Supporters of the legislation argue that permanent daylight saving time will improve public safety, encourage active lifestyles, and prevent sleep disruptions for children. Conversely, opponents, including some farming and transportation advocates, argue that late sunrises are problematic for morning commuters and agricultural workers. If enacted, the law would allow states currently on standard time, such as Hawaii and Arizona, to maintain their current exemptions.
Daylight saving time was originally adopted in 1918 to conserve energy during World War I. While it has been consistently observed since the 1960s, a 1974 Department of Transportation study found minimal benefits regarding energy conservation or safety. Currently, most of the U.S. is observing daylight saving time, which began on March 8 and is scheduled to end on November 1.
