The House voted to make Daylight Saving Time permanent. Here’s what’s next
Senate Uncertainty Looms Over Permanent Daylight Saving Time After House Approval
The House voted to make Daylight – Lawmakers in the US House of Representatives cast a decisive bipartisan vote on Tuesday to establish year-round Daylight Saving Time nationwide. Despite this momentum, the legislation’s journey through the Senate remains unpredictable. Senate Republican leadership has yet to clarify whether they will schedule the “Sunshine Protection Act” for a full floor consideration.
Majority Leader John Thune has historically resisted proposals to lock the nation into permanent Daylight Saving Time. Nevertheless, during Wednesday’s press interactions, he declined to eliminate the possibility of scheduling a future vote on the matter. This represents a subtle shift from his previous stance, though he maintains reservations about imposing a blanket mandate.
Thune’s Evolving Position on the Measure
Representing South Dakota, Thune acknowledged that reporters’ questions prompted him to reconsider his earlier opposition. He emphasized that the House-passed version includes flexibility for states preferring permanent standard time. Under the current proposal, states may opt out of switching to Daylight Saving Time, provided they commit to permanent standard time before implementation.
“I think the main concern is that there’s optionality for states, and my understanding is that’s in the House bill. I just don’t think we want a mandate and that was tried once before and repealed,” Thune explained to reporters at the Capitol.
He further noted that while some Republican colleagues support the initiative and others oppose it, the leadership is actively reviewing the proposal. When questioned about securing the 60 votes necessary to overcome a filibuster, Thune responded that the outcome remains uncertain. He admitted that the Senate has not extensively examined this particular challenge yet.
Thune also highlighted his geographic background, noting that he comes from a northern climate. This factor influenced his previous opposition when the Senate Commerce committee considered a similar measure last April. His position reflects concerns about darker mornings in northern regions during winter months.
Cotton’s Staunch Opposition Creates Hurdles
Senator Tom Cotton of Arkansas has emerged as a formidable opponent of year-round Daylight Saving Time. His steadfast resistance has diminished expectations that the Senate will swiftly approve the legislation through unanimous consent—a process requiring all 100 senators to agree to an expedited vote.
Cotton has warned that later sunrises would endanger children who must commute to school in darkness. He and other critics argue the change would negatively impact workers such as construction crews, farmers, and factory employees who would need to begin their shifts before dawn.
Some regions across the United States experience sunrise times extending past 9 a.m. during Daylight Saving Time periods. This reality fuels concerns among opponents who believe permanent Daylight Saving Time would exacerbate morning darkness for vulnerable populations and essential workers.
Cotton’s vocal opposition has made Republican leadership cautious about dedicating valuable floor time to an issue he is likely to filibuster. His warnings about safety concerns for schoolchildren and economic impacts on workers have resonated with colleagues who share similar priorities.
Historical Precedents Shape Current Debate
Congress has previously attempted to establish permanent Daylight Saving Time. During the 1970s energy crisis, lawmakers adopted such a measure but quickly reversed course when public opposition grew intense. This historical precedent informs current discussions about whether permanent Daylight Saving Time would face similar challenges.
In 2022, senators successfully passed a Daylight Saving Time bill through swift floor action without objections from colleagues. However, the legislation did not receive a House floor vote. Cotton subsequently revealed that he would have blocked that effort and pledged to object to any future attempts at rapid passage.
The most recent attempt occurred in 2025, when a bipartisan coalition of senators sought unanimous consent to enact year-round Daylight Saving Time. Cotton’s intervention prevented the measure from advancing, demonstrating his continued commitment to opposing the change regardless of party affiliation.
As the Senate considers its next steps, the combination of Thune’s openness to a floor vote and Cotton’s determined opposition creates a complex political landscape. The outcome will depend on whether enough senators can find common ground to overcome procedural hurdles and secure the necessary support for permanent Daylight Saving Time.
