Trump wants permanent daylight saving time, but the clock fight is not something a president can settle alone. The real question is whether Congress can agree on what should replace the twice-a-year switch.
Daylight saving time ends on Nov. 1 at 2 a.m. in most of the United States, and most Americans will still fall back this year unless Congress acts. Donald Trump wants daylight saving time to be permanent, but he can’t cancel the Nov. 1 clock change without Congress because federal law controls the clock rules.
That makes the current fight less about whether people are tired of changing clocks and more about who has the power to change the system. For now, the Senate is where the daylight saving debate runs into its biggest uncertainty.
The law still controls the clock
The basic household question has a straightforward answer: unless federal law changes before Nov. 1, the usual fall clock change remains in place for most of the country.
Under the current system, daylight saving time begins on the second Sunday in March and ends on the first Sunday in November. This year, that means clocks move back at 2 a.m. local time on Sunday, Nov. 1, returning most of the United States to standard time.
A president can support a different system, pressure lawmakers or sign a bill if one reaches the desk. But presidential preference alone does not rewrite the federal rules that govern time changes.
That is why Trump’s support for permanent daylight saving time is a political push, not an immediate legal change. Congress would have to pass legislation to alter the clock rules, and the president would then sign it.
Nov. 1 remains the practical date
For most households, the visible effect of the current law is familiar: clocks shift back from 2 a.m. to 1 a.m. local time. The weekend brings an extra hour of sleep for many people, followed by earlier sunsets and more morning daylight.
Phones and other connected devices usually adjust automatically. Analog clocks, ovens, microwaves and car dashboards may still need the old manual reset.
There are exceptions to the national pattern. Hawaii, most of Arizona and several U.S. territories, including Puerto Rico, Guam, American Samoa, the Northern Mariana Islands and the U.S. Virgin Islands, do not observe daylight saving time.
Most of Arizona stays on standard time year-round, while the Navajo Nation observes daylight saving time. Those carve-outs are part of why any national clock overhaul would require decisions about how states and territories are treated.
Trump is pushing permanent daylight
Trump’s position is to end the twice-a-year clock switch by keeping daylight saving time year-round. That would mean more light later in the day, including during months when the country currently returns to standard time.
Supporters of permanent daylight saving time often frame it around convenience and commerce: later sunsets can be useful for families, businesses, commuters, sports leagues and people who want daylight after work or school.
USA Today reported that Trump has personally called politicians to support the effort. The outlet quoted him saying, “Hopefully the Senate’s going to approve that one.”
The wording around this issue can get slippery. Some people say they want to “end daylight saving time” when they mean they want to stop changing clocks. Others mean they want permanent standard time. Trump’s stated aim is permanent daylight saving time, which emphasizes evening light.
Congress is the real bottleneck
The daylight saving debate has already had moments of momentum. The U.S. Senate passed the Sunshine Protection Act in 2022, a proposal to make daylight saving time permanent, but the broader effort did not become law.
According to USA Today, lawmakers have continued debating proposals to stop seasonal clock changes, and the House passed a bill in July to make daylight saving time permanent.
The obstacle now is the Senate. Sen. John Thune, a South Dakota Republican and Senate majority leader, has questioned whether a permanent daylight saving measure has enough support to pass.
That uncertainty matters because this fight does not split Washington in the usual partisan pattern. Many Democrats and Republicans dislike the current system, but agreement that the clock change is annoying does not settle what should replace it.
Voters dislike the switch
Public frustration helps explain why the issue keeps returning. A 2023 YouGov survey cited by USA Today found that 62% of Americans favored eliminating the twice-yearly clock changes.
But dislike of the switch is not the same as agreement on a replacement. A January 2025 Gallup poll cited in the same reporting found stronger support for year-round standard time than for permanent daylight saving time.
Gallup found that 48% preferred permanent standard time, while 24% favored permanent daylight saving time. That divide captures the problem facing lawmakers: the current system is unpopular, but the alternatives create their own tradeoffs.
Permanent daylight saving time benefits people who value evening light. Permanent standard time favors morning light. Keeping the current system avoids choosing one national preference, but it also preserves the disruption many people say they want to end.
Health experts favor standard time
Sleep researchers have often been more cautious about permanent daylight saving time than its political supporters. Erik Herzog, a biology and neuroscience professor at Washington University in St. Louis and former president of the Society for Research on Biological Rhythms, told USA Today that permanent standard time would be the healthiest option.
The health argument centers on circadian rhythm, the body’s internal timing system. Morning light helps regulate sleep and wake cycles. Later daylight in the evening may be convenient socially, but it can also push schedules later and make sleep harder for some people.
The spring transition, when clocks jump forward by an hour, is often singled out as the most difficult shift. Researchers have linked that disruption to short-term increases in problems such as heart attacks and car crashes.
That is why the debate is not simply “change clocks” versus “stop changing clocks.” Many experts want to stop the changes by staying on standard time. Trump and many permanent-daylight supporters want to stop them by staying on daylight saving time.
What could change before fall
If Congress passes permanent daylight saving legislation, lawmakers would still need to decide when the change begins and how the new system applies to places that already do not observe daylight saving time.
Until that happens, the legal calendar is unchanged. Daylight saving time still ends Nov. 1 at 2 a.m. in most of the United States.
The broader lesson is that a popular complaint does not automatically produce a simple federal fix. Trump can elevate the issue, lawmakers can draft bills, and voters can say they are tired of the routine. But Congress has to choose the replacement before the country stops falling back.
