The House passed the Sunshine Protection Act 308-117 on Monday, the closest permanent daylight saving time has ever been to becoming law. The bill keeps clocks on the time we use March through November — the spring-forward stays, the fall-back goes. President Trump has signaled he'll sign it. Nineteen states have already passed laws contingent on exactly this moment. Now it goes to a Senate where the path is uncertain, and where the medical community is arguing that Congress locked in the wrong clock.

1. Ending the Switch Is Worth It (House Majority, Trump, Business)

Most people hate the clock change, and Congress finally did something about it — even if doctors disagree with the choice.

Clock changes cost $672 million a year in health damage. Every March, emergency departments see spikes in heart attacks, strokes, workplace injuries, and traffic accidents — all tied to the disruption of the spring transition alone. Ending the switch eliminates that cost, regardless of which clock becomes permanent. Rep. Frank Pallone (D-NJ): "I don't really know anybody who wants to change the clock anymore."

Evening light drives economic activity. Tourism, restaurants, retail, and recreation all benefit when people have daylight after work. The golf industry alone projects nearly $1 billion in additional revenue under permanent DST, per National Golf Course Owners Association CEO Jay Karen's Senate testimony in April 2025. Rep. Gus Bilirakis, the House Energy Commerce Committee chairman who steered the bill: "Having more predictable daylight hours is a practical improvement that benefits workers, businesses and visitors alike."

Most Americans want this. A 2025 AP-NORC poll found 56% of Americans prefer permanent DST; 75% want to end the switch. Nineteen states have already passed contingent laws enabling year-round DST. The margin — 308-117 — crossed party lines and met the threshold for a supermajority.

2. But Doctors Say We Picked the Wrong Clock (AASM, AMA, Stanford)

The medical community agrees the switch should end. They just think permanent standard time is the right answer, not this.

Standard time fits human biology better than DST does. The human circadian cycle averages slightly longer than 24 hours — it needs morning light to stay calibrated. Permanent DST shifts light away from mornings and into evenings, the opposite of what the body needs. Dr. Fariha Abbasi-Feinberg, president of the American Academy of Sleep Medicine: "Permanent standard time is the healthier choice for all Americans." The AASM's position statement in the Journal of Clinical Sleep Medicine says permanent DST "has been associated with risks to physical and mental health and safety."

The best data we have favors standard time. A 2025 Stanford Medicine study led by sleep researcher Prof. Jamie Zeitzer found that permanent standard time would mean 2.6 million fewer Americans with obesity and 300,000 fewer stroke cases compared to the current switching system. Permanent DST would also reduce both — but by less: 1.7 million fewer obesity cases, 220,000 fewer strokes. Zeitzer: "You generally need more morning light and less evening light to keep well synchronized to a 24-hour day."

Congress already has a competing bill for permanent standard time. The American Medical Association voted in 2022 to support standard time over DST. Reps. Mary Gay Scanlon (D-PA) and Pat Harrigan (R-NC) introduced the Sunshine for Our Kids Act as the science-backed alternative. Scanlon on the House floor: "Millions of Americans will wake up during the winter months in complete darkness with the sun not rising until long after people get up and travel to school or work."

3. The Senate Isn't Moving (Cotton, Thune, Farm-State Republicans)

Tom Cotton is blocking it, the Senate Majority Leader won't commit, and there's a 50-year-old precedent against doing this.

Congress tried this before and reversed it fast. In January 1974, President Nixon signed year-round DST as an emergency energy measure. Public support fell from 79% to 42% within months. In Florida alone, morning traffic accidents killed 8 children in the weeks after the change. Florida's governor called for repeal. Congress reversed the law before the two-year experiment was up.

One senator plans to kill this in the Senate. Sen. Tom Cotton (R-AR) is asking Senate Majority Leader John Thune not to schedule a floor vote. His objection: workers in northern and Midwestern states would see winter sunrises pushed past 9 a.m., darkening morning commutes and school routes. Cotton says he made a "mistake" in 2022 by not personally blocking the Senate's accidental unanimous-consent passage of nearly identical legislation. He's vowed not to repeat it.

The Senate Majority Leader isn't committing. Thune told NBC News: "I just don't think we want a mandate, and that was tried once before and repealed, but we're looking at it." The bill sits in the Senate Commerce Committee with no hearing scheduled. The 22 House Republicans who voted against it came disproportionately from Midwest and farm-state districts, where permanent DST would push winter sunrises past 9 a.m.

Where This Lands

The House vote is the strongest signal in eight years that permanent DST has real political support — 308-117 with Trump behind it makes that hard to dismiss. Medical groups are more unified than ever: virtually every major sleep and health organization is on record saying Congress should have locked in standard time, not daylight saving time. And Cotton has already blocked this bill once in the Senate. Whether Thune schedules a floor vote is the only open question.
