The U.S. House voted 308-117 on July 14 to make daylight saving time permanent and sent H.R. 139 to the Senate, putting the fight over the clock change squarely in the Senate’s lap. The measure would end the twice-yearly switch and keep the country on one time year-round.
That is why the bill is drawing new attention now. President Donald Trump has signaled support for making daylight saving time permanent, but whether enough senators will back the idea remains unclear, and the Senate version, S. 29, has been stuck since it was referred to the Senate Committee on Commerce, Science, and Transportation on Jan. 7, 2025. The House vote gives the proposal momentum, but it does not settle the harder question of whether the Senate will move it at all.
For New Hampshire, the issue is less about how much daylight exists than when people see it. Permanent daylight saving time would leave the state with darker mornings in fall and winter and brighter evenings after work and school. Under that schedule, some winter sunrises would not come until slightly after 8 a.m., and many Granite Staters would see sunrise closer to 8 a.m. or later in December and January. Summers would stay much as they are now.
The basic mechanics are already familiar. Under daylight saving time, clocks move forward one hour at 2 a.m. on the second Sunday in March, then move back one hour at 2 a.m. on the first Sunday in November. The longest day of the year was June 21 this year, and the shortest day will be Dec. 21. Using Portsmouth as a guide for those extremes shows what permanent daylight saving time would really change: not the amount of daylight, but the balance between early-morning light and evening light.
That balance is where the push runs into its biggest problem. Bright winter evenings are easy to sell, but darker winter mornings are harder to dismiss, especially in a place where school buses, commuters and early workers start the day before the sun is fully up. The House has already voted, but the Senate has not yet shown that S. 29 has the votes to become law.
So the next step is plain enough: the Senate must decide whether to take up the bill and whether enough senators are willing to lock the nation into daylight saving time all year. Until that happens, the clock change remains a proposal with House support and an uncertain future in the Senate.
