WASHINGTON, DC — Congress may soon get another chance to decide whether Americans keep daylight saving time all year, a change that has already been approved in some form by 19 states. The Sunshine Protection Act passed the House earlier this year and is now sitting in the Senate, where it has been stalled since July.
The measure would make daylight saving time permanent nationwide, with limited exceptions. If senators take it up and approve it, the bill could still become law with President Trump having said he supports the idea. Without action, clocks will “fall back” to standard time on November 1, the first day daylight saving time can end this year.
House approval gives permanent daylight saving time its best opening in years
The current version of the Sunshine Protection Act cleared the House this year, reviving a debate that has hovered over Washington for years. A similar effort passed the Senate in 2022 but did not advance in the House, leaving the issue unresolved despite repeated interest from states and lawmakers.
That makes this summer and fall the closest the country has come in years to ending the switch between daylight saving time and standard time. The Senate’s return from recess gives the proposal a possible path forward, although there is no guarantee it will come up for a vote or reach the floor at all.
Supporters argue the shift would settle a long-running question for businesses, families, and states that have already acted on their own. Opponents, or senators who simply have not made the bill a priority, could still keep the measure from moving, even if there is enough momentum outside Congress.
Nineteen states have passed their own daylight saving time laws
States cannot unilaterally make daylight saving time permanent under current federal rules, but that has not stopped lawmakers in 19 states from passing legislation that would do exactly that if Congress gives the green light. Those states have effectively lined up in anticipation of federal approval, even if the changes cannot yet take effect.
Florida was first, approving its request for year-round daylight saving time in 2018. Since then, state lawmakers elsewhere have followed suit, with Maine and Texas joining the list last year.
Other states that have enacted similar measures include Alabama, Georgia, Louisiana, Minnesota, Mississippi, Oklahoma, South Carolina, and Tennessee. The laws are on the books, but they remain dormant until the federal barrier is removed.
Some states tied their plans to action by neighboring states
Several of the enacted state laws include conditions that depend on nearby states making the same move. Delaware, for instance, said its change would take effect only if Maryland, New Jersey, and Pennsylvania also adopt permanent daylight saving time. None of those three states has done so yet, although bills in New Jersey and Pennsylvania remain alive.
Western states have created similar triggers. Colorado, Wyoming, Utah, Montana, Idaho, and Washington all passed legislation that assumes neighboring states will also lock their clocks. Oregon passed a measure too, but it says Malheur County would be excluded and still depends on California taking action.
California voters authorized lawmakers to make the switch in 2018, but the state has not done so. That has left several neighboring efforts waiting for a domino effect that has never quite arrived, even as the bills continue to sit on state books.
Some states still prefer permanent standard time instead
The Sunshine Protection Act is not the only clock-change proposal in play. Under current law, states may choose year-round standard time instead, and a number of legislatures considered that option this year as well.
Those efforts failed in places including Michigan, New Jersey, and Pennsylvania, though legislation in those states remains alive. Hawaii and most of Arizona already stay on permanent standard time, showing that the federal system does allow one form of year-round clock setting.
For now, the federal debate leaves states with limited choices: they can pursue permanent standard time on their own, or pass daylight saving time legislation that remains frozen until Congress acts. That is why the pending Senate vote matters so much to states that have already passed related measures.
Senate timing will decide whether clocks change again in November
Whether the bill moves forward may depend on how quickly senators choose to act after returning from recess and whether there are enough votes to clear the chamber. The proposal has been waiting since July, and its fate remains uncertain despite the House vote and support from the White House.
If the Senate does not take up the bill soon, the country will continue the familiar cycle of springing forward and falling back. The next deadline comes on November 1, when daylight saving time is scheduled to end at the earliest possible date.
That would leave the 19 states with approved legislation still waiting, along with residents across the country who would be affected by a permanent shift. For now, however, no state is on the verge of locking its clocks on daylight saving time.
