U.S. Daylight Saving Time: Could the Clock Changes End?

A House-approved bill would keep daylight saving time year-round, but it still needs Senate approval before the U.S. could change its clock rules.

The short version

The U.S. could stop changing clocks only if Congress passes a law; the bill for year-round daylight saving time has passed the House but still faces obstacles in the Senate. ¹²
President Donald Trump is pressing Senator Tom Cotton of Arkansas to support the bill. ¹²
Supporters say permanent summer time would add daylight during the hours many people are active; opponents warn of darker winter mornings for children and commuters. ²
Most of the U.S. observes daylight saving time, but Arizona, Hawaii and several territories do not. ⁴

Will the U.S. stop changing the clocks?

Not yet. As of October 6, 2026, the proposal to keep daylight saving time all year has passed the House of Representatives, but it has not cleared the Senate. It would need to pass the Senate and become law before the national clock rules changed. ¹²

The bill is called the Sunshine Protection Act. It would make daylight saving time permanent rather than switching between it and standard time during the year. The available reports do not say that the Senate has approved it. ¹²

Why is daylight saving time in the news?

President Donald Trump has publicly urged Senator Tom Cotton, a Republican from Arkansas, to support the bill. Trump also encouraged people to call Cotton, and news reports say he shared a number associated with the senator. ¹²³

The disagreement is about more than the inconvenience of changing clocks. Cotton and other opponents have raised concerns about darker winter mornings, while Trump and other supporters favor having more daylight later in the day. ¹²

What would permanent daylight saving time mean?

Under the proposal, the country would stay on daylight saving time throughout the year instead of moving clocks back and forth. Daylight saving time shifts the clock forward by an hour compared with standard time, giving evenings more daylight and mornings less. ¹⁴

Supporters argue that the arrangement would put more daylight in the hours when people are active. Critics point to winter mornings: children could wait for school buses and adults could travel to work while it is still dark. ²

Would every state change its clocks?

The supplied background source says most of the United States observes daylight saving time. Arizona and Hawaii are exceptions, as are American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands. ⁴

The sources provided do not explain how the proposed law would apply to each state or territory, or whether the existing exceptions would change. The proposal's details should be checked against the final law if it advances.

When will the clock rules change?

There is no confirmed date for a change to permanent daylight saving time in the available reports. The House vote is only one step; the Senate remains a hurdle. ¹²

For now, the proposal is a political and legislative dispute, not a completed change to the rules. The sources do not establish whether or when the Senate will act.

What we don't know yet

Whether the Senate will pass the Sunshine Protection Act.
Whether a final version would preserve current exceptions for states and territories.
If the bill becomes law, when any new clock rules would take effect.
