The U.S. House will vote this week on a bill making daylight saving time permanent, despite warnings from medical, education and safety organizations.

The Sunshine Protection Act of 2025, which would end the nearly nationwide biannual clock changing and make daylight saving time permanent year-round, advanced out of committee Monday afternoon.

States that use standard time year-round — currently only Arizona and Hawaii — before the law goes into effect wouldn’t have to change.

House Energy and Commerce Committee ranking member Frank Pallone, D-N.J., testified in support of the bill, which Rep. Vern Buchanan, R-Fla., introduced.

Pallone argued that changing the clocks every year is widely unpopular with Americans and that making daylight saving time permanent would boost the tourism industry.

“The real question is, why do we still change our clocks?” Pallone said. “It’s getting harder and harder to justify.”

Besides the U.S. tourism industry, retail and golfing industries have long lobbied Congress to permanently set the clocks an hour ahead.

“Our industry is uniquely tied to daylight, and the number of playable hours directly affects the number of rounds we can offer, the staff we employ, and the revenue we generate, especially in the late afternoon and early evening,” National Golf Course Owners Association CEO Jay Karen told lawmakers in 2025.

“We ask the Senate to consider the practical and economic consequences of losing evening daylight.”

The U.S. Chamber of Commerce, National Retail Federation, National Association of Convenience Stores, the American Farm Bureau Federation and others have expressed support for making daylight saving time permanent.

But medical professionals, education advocates and safety professionals overwhelmingly support making standard time permanent instead.

“By artificially shifting the clock time an hour forward, daylight saving time causes a misalignment between clock time and solar time, interfering with our circadian timing and resulting in a condition known as ‘social jet lag,’’ the American Academy of Sleep Medicine stated in its opposition to the bill.

“This condition is associated with an increased risk of obesity, metabolic syndrome, cardiovascular disease, and depression. If daylight saving time becomes permanent, then Americans will be living with social jet lag year-round.”

The American Medical Association, American College of Occupational Medicine, National Sleep Foundation, American Federation of Teachers, National School Boards Association, National Safety Council, and dozens of other organizations have endorsed permanent standard time.

Congress tried to implement permanent daylight saving time in the 1970s.

The two-year trial lasted less than a year, however — in a 1974 speech on the Senate floor, the former U.S. senator for Kansas Bob Dole said the change “is a classic example of the Congress legislating blindfolded.”

“It has caused great inconvenience and in some cases hazard. It appears to me that the better part of wisdom might be outright repeal,” Dole said. “After spending the first 3 weeks of winter daylight time in Kansas, I became more convinced than ever that its hardships, inconvenience, and real hazards are too great to justify its continuation.”

If the Sunshine Protection Act does pass the House on Tuesday, its future in the Senate is uncertain as it will need at least 60 votes to pass.
