The fight over permanent daylight saving time is carving a distinct geographic divide through Congress. Lawmakers from some states are eager to lock the clocks year-round, while others warn of dangerously dark winter mornings.
This legislative battle intensified after the House passed the Sunshine Protection Act of 2025 in a sweeping 308-117 bipartisan vote. The legislation, which carries the endorsement of President Donald Trump, aims to end the nation’s twice-yearly time shifts entirely.
However, the bill now faces a fierce and uncertain reality in the Senate.

States Pushing for Endless Sunshine
Nineteen states are fully prepared to lock in daylight saving time, having already passed legislation that triggers if federal law permits it. According to the National Conference of State Legislatures (NCSL), this roster includes Florida, Texas, Washington, Tennessee, Utah, Georgia, and Montana.
Because current federal law forbids states from adopting permanent daylight time independently, congressional approval remains the final hurdle.
Advocates insist that ditching the seasonal clock shifts will stabilize sleep schedules and inject much-needed sunlight into winter evenings. Florida Senator Rick Scott remains one of the proposal’s most aggressive champions.
“Let’s leave the decision up to the states so we don’t have to change our clocks twice a year,” Scott said earlier this month. “I’m thrilled that the house has finally passed it. The Senate needs to take it up NOW and send it to President Trump‘s desk.”
The Resistance from the North and West
Despite the overwhelming House vote, severe pushback is brewing in the Senate. Lawmakers representing northern and western states argue the permanent time shift would impose severe morning hardships on their constituents.
Arkansas Senator Tom Cotton is fiercely leading the opposition. He argues that delayed winter sunrises would force commuters, farmers, construction workers, and children to navigate total darkness.
“I will always oppose any effort to adopt daylight savings time year-round,” Cotton stated publicly.
South Dakota Senator Mike Rounds echoed this blunt assessment. “It doesn’t work in South Dakota,” Rounds explained. “I mean, we’d have kids going to school in the dark until 9 o’clock, 9:30 in the morning. It won’t work.”
This stark regional split explains why Senate leaders have yet to commit to bringing the bill to a floor vote.

The Standard Time Holdouts
Two states—Arizona and Hawaii—are largely watching the debate from the sidelines. Both states already remain on standard time permanently and bypass daylight saving time entirely.
According to the National Institute of Standards and Technology, Hawaii and the vast majority of Arizona ignore the spring and fall shifts. The only exception is the Navajo Nation in Arizona, which does observe daylight saving time.
Under the parameters of the Sunshine Protection Act, these holdout states would maintain their right to stay on permanent standard time.
Echoes of a Failed Experiment
The hesitation in the Senate is not without historical precedent. The United States actually tried permanent daylight saving time in 1974 under President Richard Nixon during an energy crisis.
The experiment was a rapid failure. Congress reversed course early after public outrage spiked over children waiting for school buses in pitch-black conditions.
While the House has signaled a strong desire to kill the clock changes, the Senate math remains complicated. Until proponents can convince skeptical senators that brighter evenings justify darker mornings, Americans will continue falling back and springing forward.
