President Trump renewed his push Friday for Congress to make daylight saving time permanent, calling on Senate Republicans to advance legislation that would end the practice of changing clocks twice a year.

“Republicans in the Senate have to get moving on what I call the ‘No More Changing of Clocks Act,’ officially known as The Sunshine Protection Act,” Trump said.

The House already passed the legislation in July by a bipartisan 308-117 vote. The measure received support from 193 Republicans, 114 Democrats and one independent before being sent to the Senate, where it was referred to the Commerce Committee.

Trump argued that Americans are tired of adjusting their clocks every spring and fall and said permanent daylight saving time would provide an additional hour of daylight in the evening.

“People don’t want to go around changing their Clocks anymore and, besides, far and away, most people like having an hour of extra sunlight in the evening, rather than in the morning,” Trump wrote.

The president also criticized the costs and disruptions he associates with the current system, arguing that changing clocks affects everything from businesses and sporting events to public safety and daily routines.

Trump specifically called out Sen. Tom Cotton, R-Ark., accusing him of holding up the legislation in the Senate.

“Unfortunately, it’s being held up by Senator Tom Cotton, of Arkansas,” Trump said.

Cotton has previously opposed making daylight saving time permanent, citing concerns about darker winter mornings. In a 2025 Senate speech, Cotton pointed to the failed nationwide experiment with year-round daylight saving time in the 1970s and warned that permanent daylight saving time could leave children traveling to school in darkness during the winter.

The disagreement highlights a broader debate over what time standard the country should use if seasonal clock changes are eliminated. Trump supports keeping daylight saving time year-round, while some medical and sleep organizations have argued that permanent standard time would better align with human circadian rhythms.

The timing is becoming increasingly important because the current law still requires most Americans to fall back one hour on Nov. 1. Unless Congress acts, the twice-yearly clock change will continue this year.

The Senate is currently the remaining hurdle for the Sunshine Protection Act. Trump is urging Republicans to move the bill forward, while lawmakers continue to debate whether the country should permanently adopt daylight saving time or permanent standard time.

The issue has attracted support from both Republicans and Democrats in Congress, with the House vote demonstrating the bipartisan coalition behind ending the clock changes even as lawmakers remain divided over which time standard should become permanent.
