The U.S. House on Tuesday passed legislation that would make daylight saving time permanent year-round, ending the twice-yearly clock changes that have defined American life for decades. The Sunshine Protection Act received bipartisan support in a 308–117 vote and now moves to the Senate.
Twenty-two Republicans joined 95 Democrats in opposing the measure, reflecting divisions within both parties over the policy change. President Donald Trump has repeatedly urged Congress to end the practice of changing clocks, calling the current system "a ridiculous, twice-yearly production" and urging Republicans to support what he called "the far more popular alternative."
What the Right Is Saying
Republican supporters argued the legislation reflects practical realities and constituent preferences. Rep. Kat Cammack (R-FL) asked why Americans are still changing clocks twice yearly, noting that Floridians value sunshine as part of their state's identity.
Fellow Florida Republican Rep. Gus Bilirakis emphasized the measure transcended political divisions. "This is not about politics," he said. "This is about practicality. It is about recognizing that our laws should keep pace with the people we represent."
President Trump has positioned the change as a quality-of-life improvement for Americans, arguing the current system creates unnecessary disruption and that permanent daylight saving time enjoys broader public support.
What the Left Is Saying
Democratic opponents raised concerns about morning darkness affecting children traveling to school. Rep. Steny Hoyer (D-MD) said he was not in favor of the measure, stating that having kids go to school when it is dark does not make sense.
Several medical organizations aligned with progressive viewpoints have argued against permanent daylight saving time, contending that standard time better aligns with the body's natural circadian rhythm because it provides more morning sunlight. These groups argue that exposure to morning light is essential for health and cognitive function.
Some Democrats also echoed concerns about winter months, when permanent DST would push sunrise to even later hours in northern regions of the country.
What the Numbers Show
The House vote was 308–117, requiring a two-thirds majority under the suspension process used for passage. This indicates substantial bipartisan agreement on ending clock changes.
Research cited by the American Heart Association has documented increases in heart attacks and strokes in the days following the springtime transition when clocks move forward an hour.
A University of Colorado Boulder study found a 6% increase in fatal car crashes during the workweek following the spring time change. The research suggests sleep disruption from losing an hour contributes to driver impairment.
Daylight saving time was first adopted nationally during World War I and later standardized under the Uniform Time Act of 1966. Currently, most of Arizona, Hawaii, Puerto Rico, and the U.S. Virgin Islands do not observe daylight saving time at all.
Under the proposed legislation, states could only opt out if they did so before the law took effect. The bill would keep clocks set to the time currently observed from March through November for the remainder of the year.
The Bottom Line
The House passage marks the furthest federal legislation on this issue has advanced in years, but significant hurdles remain. The Senate has not scheduled consideration of the Sunshine Protection Act, and its path forward is unclear.
If enacted, the measure would represent a fundamental shift in how Americans experience daylight throughout the year. Permanent daylight saving time would mean later sunsets in summer evenings but darker mornings during winter months, particularly in northern states.
States currently exempt from daylight saving time—including Arizona, Hawaii, and several U.S. territories—could maintain their current arrangements only by opting out before implementation. Advocates say the change would reduce health risks associated with seasonal clock shifts, while critics contend it would create new problems for morning routines and winter travel safety.
