Trump’s push to stop changing the clocks now includes a claim about crime. The proposal has bipartisan frustration behind it, but experts remain divided over whether permanent daylight saving time is the best answer.
Donald Trump said permanent daylight saving time could cause the murder rate to fall, linking later evening daylight to public safety as he urged Congress to make daylight saving time permanent. His proposal would end the twice-yearly clock changes for much of the United States, but the claimed effect on murders is not established by the legislative debate now before Congress.
The political appeal is easy to see: no more lost hour in spring, more light after work and school, and a possible crime-prevention argument. The harder question is whether permanent daylight saving time, rather than permanent standard time, would produce the best overall result.
Trump adds crime to clock debate
Trump has argued that the House and Senate should pursue “more Daylight at the end of a day.” In an earlier Truth Social post reported by NPR, he called the clock changes an inconvenience and a costly event for government.
The newer claim that permanent daylight saving time could bring down the murder rate broadens the case beyond convenience. It rests on a common-sense proposition: more people are out in daylight during the evening, and some types of crime may be less likely or easier to deter when streets and public spaces are brighter.
That is a plausible policy question, but it should not be confused with a demonstrated national prediction. Murder rates move with many factors, including local policing, gun availability, economic conditions, demographics, reporting practices and broader crime trends. Changing the clock would be only one variable among many.
What permanent daylight saving time means
Daylight saving time shifts clocks ahead by one hour, creating later sunset times by the clock during the warmer part of the year. Making it permanent would mean keeping that later clock setting through winter instead of returning to standard time.
For many Americans, the immediate benefit would be the end of the spring-forward and fall-back routine. Supporters say that would make schedules more predictable and preserve usable light later in the day, when people commute, exercise, shop or spend time outdoors.
But the tradeoff is especially sharp in winter. Permanent daylight saving time would push sunrise later in many places, meaning some children would travel to school and some workers would begin their day in darker conditions.
- Permanent daylight saving time: more evening light by the clock, with darker winter mornings.
- Permanent standard time: earlier winter sunrise, with earlier evening darkness.
- The current system: a seasonal switch that offers later light in spring and summer but disrupts schedules twice a year.
The legislation has stalled before
Congress has considered versions of this idea for years. The Sunshine Protection Act was introduced again in the House by Florida Rep. Vern Buchanan and in the Senate by Florida Sen. Rick Scott, according to NPR. Then-Sen. Marco Rubio had championed earlier versions.
The Senate passed the measure unanimously in 2022, but the House did not bring it to a vote. That history is a reminder that widespread annoyance with clock changes does not automatically settle the more difficult question of which time system should replace them.
Federal action matters because states cannot simply choose permanent daylight saving time on their own under current law. States may opt out of daylight saving time and remain on standard time all year, but a nationwide or state-level shift to year-round daylight saving time requires Congress to change the rules.
Hawaii and most of Arizona do not observe daylight saving time. The Navajo Nation, which extends into Arizona, is an exception. Several U.S. territories also stay on standard time year-round.
Why crime research needs caution
Research on light and crime can produce narrower findings than a claim about the national murder rate suggests. Studies have examined whether additional daylight affects specific offenses, locations or hours of the day. Those findings can be useful without proving that a permanent time policy would reduce homicides across the country.
Property crimes and street offenses may be more responsive to visibility and foot traffic than murders, which often occur in private settings or involve circumstances that daylight alone cannot explain. Even where later daylight is associated with lower crime at certain times, researchers must separate the effect of light from weather, seasonality, local activity and policing.
There is also an important distinction between fewer crimes occurring in an hour that becomes brighter and an overall decline in annual crime. A shift in timing is not necessarily a reduction in total harm.
Trump’s statement may prompt supporters to emphasize the potential public-safety upside of lighter evenings. Critics can reasonably respond that the available debate, at least from the information publicly described around the proposal, does not establish a direct causal link between permanent daylight saving time and a lower murder rate.
Sleep experts favor another option
The dispute is not simply between keeping the clock changes and ending them. Many sleep and medical experts oppose the twice-yearly switch but favor permanent standard time over permanent daylight saving time.
Dr. Karin Johnson, medical director of the Baystate Regional Sleep Medicine Program, told NPR that permanent standard time is more closely aligned with the sun and better for overall health and well-being. The concern is that later winter sunrises can worsen the mismatch between social schedules and the body’s internal clock.
At a Senate hearing on the issue, Texas Sen. Ted Cruz described the clock changes as outdated and harmful, while Delaware Sen. Lisa Blunt Rochester said the back-and-forth should stop. Their remarks reflected a broad point of agreement: the current switching system has costs. The disagreement is over the replacement.
That leaves Trump’s proposal with a politically attractive message but unresolved evidence questions. Ending clock changes may have support across party lines, yet Congress would still need to decide whether more evening daylight, darker mornings, potential health effects and uncertain crime outcomes add up to a policy worth making permanent.
The central choice remains unsettled
The strongest case for permanent daylight saving time is practical: people may value later light after school and work, and they may welcome an end to clock changes. Trump’s murder-rate claim adds a potentially powerful argument, but it is a claim that requires more evidence than a simple appeal to brighter evenings.
The central policy choice is therefore bigger than a preference for sunrise or sunset. Congress would be choosing which part of the day gets the extra hour of light by the clock, and which risks or benefits deserve the most weight. Until lawmakers move a bill through both chambers, Americans will continue changing their clocks while that decision remains unresolved.
