The House passed the Sunshine Protection Act on July 14 by a decisive 308-117 vote, delivering a major bipartisan victory for supporters of eliminating the twice-yearly time change. The legislation would keep most Americans on daylight saving time throughout the entire year instead of returning to standard time each November.
But there is still one major obstacle: the Senate.
The legislation was sent to the Senate after its overwhelming House victory, where its future remains uncertain. Senate leaders have not yet secured the support needed to move it through the chamber, leaving the proposal in legislative limbo.
Trump has made clear that he wants senators to act.
During remarks in Michigan on July 27, the president renewed his call to eliminate the clock changes altogether.
“Hopefully the Senate’s going to approve that one,” Trump said.
That short statement underscored a larger campaign from the White House to get the measure across the finish line.
Trump has repeatedly argued that forcing Americans to adjust their clocks twice a year is an outdated hassle that costs time, money and productivity. Earlier in the year, he said he would work hard to get the Sunshine Protection Act signed into law, describing the twice-yearly clock change as an unnecessary burden.
If Congress does not act, however, the current system remains in place. Under existing law, most Americans will continue moving their clocks forward in March and backward in November.
That means the November clock change could still be on the calendar unless lawmakers reach an agreement and President Trump signs the legislation beforehand.
Transportation Secretary Sean Duffy has also entered the fight, giving the administration’s campaign an additional argument: road safety.
Duffy urged Congress to include permanent daylight saving time in legislation dealing with federal transportation programs, which are scheduled to expire September 30. In a letter to congressional leaders, Duffy argued that moving daylight into hours when more Americans are on the roads could reduce traffic fatalities.
“Adopting permanent Daylight Saving Time would eliminate the needless time, hassle, and cost involved in changing clocks twice a year, and a study found that it would prevent hundreds of traffic deaths every year by shifting daylight to times of day when more Americans drive,” Duffy wrote.
Supporters of the bill say the benefits extend well beyond convenience.
They argue that eliminating the clock change would mean fewer disruptions to family schedules, work routines and sleep patterns. Businesses that depend on evening activity could also benefit from an additional hour of daylight during the winter.
But opponents are not backing down.
One of the strongest Republican critics is Sen. Tom Cotton of Arkansas, who has warned that permanent daylight saving time could create dangerously dark winter mornings, particularly for children heading to school.
Sen. Shelley Moore Capito of West Virginia has expressed similar concerns. For families in northern states, winter mornings can already be extremely dark. Keeping clocks permanently shifted forward could push sunrise even later, leaving some children waiting for school buses or walking to class before daylight.
That concern has become one of the central arguments against the proposal.
Critics also point to the nation’s previous experience with permanent daylight saving time. During the 1970s energy crisis, the United States temporarily adopted year-round daylight saving time. The experiment proved unpopular, and Congress ultimately reversed course after public opposition grew, including concerns about children traveling to school in darkness.
The debate also extends into the aviation industry.
Airlines have warned that changing the nation’s timekeeping system could require careful coordination with international schedules, aircraft positioning and crew assignments. A sudden transition, they argue, could create logistical headaches extending far beyond American airports.
Health experts are similarly divided over which system should become permanent.
There is broad agreement that repeatedly shifting the clock can disrupt sleep. But many medical organizations have favored permanent standard time rather than permanent daylight saving time, arguing that earlier morning sunlight is more closely synchronized with the body’s natural circadian rhythm.
That leaves Congress facing a deceptively simple question with surprisingly complicated consequences: Should America keep changing the clocks, stay permanently on daylight saving time, or choose permanent standard time?
For Trump, the answer is clear.
He wants the clock changes gone.
And this time, the House has already given him a powerful political opening.
The Senate passed a similar Sunshine Protection Act unanimously in 2022, but that legislation ultimately stalled in the House. Four years later, the political situation has been reversed: the House has acted, and the Senate is now holding the cards.
The overwhelming 308-117 House vote shows that ending the clock changes has support across party lines. But getting through the Senate could be considerably more difficult, particularly because lawmakers remain divided over whether permanent daylight saving time or permanent standard time is the better solution.
Trump’s direct intervention could add significant pressure to the debate.
For millions of Americans, the issue may seem like a minor annoyance. But the closer Congress gets to November, the more attention the question is likely to receive.
If senators approve the measure and Trump signs it, Americans could finally stop asking when they are supposed to change the clocks.
If they fail, the familiar ritual returns once again.
And for Trump and his allies, the message to Congress is straightforward: after decades of changing the clock twice a year, it may finally be time to lock it in.
