Permanent Daylight Saving Time: How the Sunshine Protection Act Would Work

Permanent daylight saving time is not U.S. law. The Sunshine Protection Act of 2025 would eliminate the twice-yearly clock changes and establish a fixed time equivalent to today's daylight time in most places that currently change clocks. But the proposal still needs further federal action. The House passed its version, H.R. 139, on July 14, 2026, and the Senate received it on July 15. The latest action shown in the official Government Publishing Office record is referral to the Senate Committee on Commerce, Science, and Transportation—not enactment.

That means the existing rule still applies: most U.S. clocks are scheduled to move back one hour on Sunday, November 1, 2026, at 2:00 a.m. in their respective local daylight time zones. The National Institute of Standards and Technology's 2026 daylight saving time schedule confirms the date. No one needs to change their clock settings based on the bill alone.

What would the Sunshine Protection Act actually change?

Under the House-passed text of H.R. 139, Congress would repeal the federally defined temporary daylight saving period and move the legal standard-time offsets forward by one hour. In everyday terms, much of the country would keep the clock setting currently used in spring and summer all year.

Instead of switching between Eastern Standard Time (EST, UTC−05:00) and Eastern Daylight Time (EDT, UTC−04:00), for instance, a location that followed the new arrangement would use a fixed UTC−04:00 clock year-round. The bill changes how standard time is defined in federal law; it is not a plan to add an hour to the physical length of a day, extend the amount of winter sunlight or shift sunrise itself.

The table illustrates the proposed effect for places that currently observe the seasonal change. States and areas already exempt from daylight saving time receive a distinct choice under the bill; existing territorial and local exceptions require separate attention. The table does not mean the proposal has taken effect.

What would happen to morning and evening daylight?

Consider a purely illustrative winter day in a location that now uses standard time. If sunrise is shown as 7:00 a.m. on the current winter clock, it would appear as 8:00 a.m. under a clock that stays one hour ahead. If sunset is shown as 5:00 p.m., it would appear as 6:00 p.m. The Sun would rise and set at the same physical moments; only the civil-time labels would be different.

For someone who finishes work late in the afternoon, that could make more daylight available after work. For someone commuting to an early shift or a child walking to school, sunrise would occur later by the clock, potentially increasing time spent outdoors in morning darkness. The impact depends on latitude, location within a time zone, school and work schedules, and the season. Neither side of the debate can promise the same benefit for every community.

There would also be no additional one-hour jump each spring or repeated hour each fall after a permanent system was fully established. However, the bill text does not supply a detailed nationwide operational schedule for every clock, software system and service. An enactment date, implementation instructions and any subsequent amendments would need to be checked before predicting precisely when devices should change.

Would Arizona and Hawaii have to change?

Not automatically. One important detail in H.R. 139's text is a specific option for a state, or an eligible area within a state, that was already exempt from the federal daylight saving requirement immediately before enactment. Such a jurisdiction could choose the newly advanced standard offset or its prior standard offset. This is narrower than saying every state could freely choose any clock arrangement after passage.

The current U.S. Department of Transportation guidance identifies Hawaii and most of Arizona among places that do not observe daylight saving time. The Navajo Nation in Arizona does observe it, which is why a statement about the entire state can be misleading. U.S. territories also have existing exceptions, including Puerto Rico, Guam, American Samoa, the Northern Mariana Islands and the U.S. Virgin Islands. Their precise treatment under an enacted measure should be based on the final statutory language and implementing guidance, not assumed from an example about the continental states.

Under the law as it stands today, a state may opt out of daylight saving time, but it cannot unilaterally impose permanent daylight saving time. The Department of Transportation's Uniform Time explanation makes that limit explicit. State laws favoring permanent daylight time therefore do not, by themselves, authorize a switch without federal legal change.

Where does the bill stand in Congress as of October 30, 2026?

The current proposal is not the same thing as the earlier Senate vote frequently mentioned in older headlines. In March 2022, the Senate approved a prior Sunshine Protection Act proposal, but it did not become law. The relevant measures in the 119th Congress are H.R. 139 and the separately introduced Senate bill S. 29.

The official House clerk's roll call records passage of H.R. 139 by 308 votes to 117 on July 14, 2026. The following day, the measure was read twice in the Senate and referred to its Commerce Committee. Separately, the official record for S. 29 shows it was introduced on January 7, 2025, and referred to that committee. The government legislative records checked for this article do not establish that either measure has become law.

For permanent daylight saving time to take effect through this legislation, the chambers would need to agree on legislation and it would need to complete the constitutional process for becoming law. House passage alone does not change time-zone rules. A future amendment might also alter provisions discussed here. That is why the operative text and current status matter more than a headline claiming that Congress has already eliminated clock changes.

Why is permanent daylight saving time controversial?

Supporters emphasize brighter evenings for recreation, commuting after work and neighborhood activity, along with the convenience of ending disruptive clock changes. Those are plausible goals, but they do not establish a guaranteed economic, safety or public-health effect in every location.

Sleep-health advocates distinguish ending seasonal clock changes from choosing which fixed time to keep. The American Academy of Sleep Medicine's position and historical fact sheet favors permanent standard time instead, citing closer alignment with natural circadian rhythms and concerns about darker winter mornings. Its review also describes the United States' 1974 experiment with year-round daylight saving time, which was curtailed after public objections to winter morning darkness.

That history does not answer every modern question about scheduling, lighting or safety, but it explains the central policy disagreement. Both permanent daylight time and permanent standard time would avoid the recurring seasonal transitions; they would place winter daylight at different times on the clock. Policymakers must decide which tradeoff is acceptable across a geographically diverse country.

What should you do for the November 1, 2026 time change?

Unless the law changes before then, follow the rules already published by NIST. At 2:00 a.m. Eastern Daylight Time (EDT, UTC−04:00) on November 1, clocks in places such as New York return to 1:00 a.m. Eastern Standard Time (EST, UTC−05:00). Both clock readings refer to 06:00 UTC at the transition. In Los Angeles, at 2:00 a.m. Pacific Daylight Time (PDT, UTC−07:00), the clock returns to 1:00 a.m. Pacific Standard Time (PST, UTC−08:00), corresponding to 09:00 UTC. Other observing areas transition at 2:00 a.m. in their own daylight time zones.

• For households: Check clocks and alarms that do not update automatically; leave modern network-connected devices set to the correct location and automatic time-zone rules.
• For travelers: Use a named time zone, date and UTC offset when interpreting arrival times or international reservations. Confirm airline and train schedules with the operator.
• For employers and developers: Keep time-zone databases and operating systems updated rather than hard-coding an assumed permanent UTC offset. Systems should distinguish stored UTC timestamps from locally displayed civil times.
• For residents of non-observing areas: Do not adjust a clock simply because most U.S. states are changing. Verify the rules applicable to your exact location.

Frequently asked questions

Did the Sunshine Protection Act pass?

H.R. 139 passed the House in July 2026, but passage by one chamber is not enactment. The latest verified official record shows referral to the Senate Commerce Committee on July 15, 2026. The United States has not adopted permanent daylight saving time through that bill.

Will we still fall back in November 2026?

Yes, under the rules in force as checked for this article. Most observing U.S. locations are scheduled to return to standard time on Sunday, November 1, 2026, at 2:00 a.m. in their local daylight time zone. Check for any later enacted federal change before the transition.

Is permanent daylight saving time the same as permanent standard time?

No. Both avoid seasonal switching, but permanent daylight saving time keeps the summer-style clock setting, while permanent standard time keeps the winter-style clock setting. The difference is one hour on the clock, not more or less sunlight.

Would the proposal apply everywhere in the United States?

It proposes advanced fixed offsets as the general rule, with a special choice for jurisdictions already exempt from daylight saving time before enactment. Existing exceptions, including most of Arizona, Hawaii and various territories, should not be described as automatically disappearing. Consult the final law and federal guidance if the bill advances.
