The Sunshine Protection Act is proposed legislation that would make Daylight Saving Time (DST) permanent across most of the United States. If enacted, Americans would no longer change their clocks twice a year. Instead, the country would stay on DST year-round. The bill recently passed the U.S. House of Representatives and is awaiting consideration in the Senate.

What is the Sunshine Protection Act?

The Sunshine Protection Act would:

• End the twice-yearly clock changes (“spring forward” and “fall back”).
• Keep states that currently observe DST on daylight saving time throughout the year.
• Allow states that already do not observe DST to continue using standard time.

Current Status (July 2026)

• Passed the U.S. House of Representatives: 308–117 with bipartisan support.
• Next step: Approval by the U.S. Senate.
• Final step: Signature by the President before it becomes law.
• The bill has not yet become law, and the Senate’s support remains uncertain.

Why Do Lawmakers Want Permanent DST?

Supporters say the change would:

• Eliminate the inconvenience of changing clocks twice each year.
• Reduce sleep disruption caused by seasonal time changes.
• Provide more daylight during evening hours.
• Encourage shopping, dining, sports, and outdoor recreation.
• Potentially reduce some evening traffic accidents and workplace injuries.

What Would Change?

If the bill becomes law:

• Americans would stop “springing forward” in March and “falling back” in November.
• Evening sunsets would occur approximately one hour later during winter.
• Winter sunrises would also occur approximately one hour later, meaning darker mornings.

Example 

For example, if sunrise is currently 7:00 a.m. during winter, it could occur around 8:00 a.m. under permanent DST, while sunset would also be about one hour later.

Which Places Would Not Be Affected?

Federal law already allows certain states and territories to remain on standard time year-round. These include:

• Hawaii
• Most of Arizona (except the Navajo Nation)
• Puerto Rico
• Guam
• U.S. Virgin Islands
• American Samoa
• Northern Mariana Islands

These jurisdictions would generally continue their existing time practices unless federal law changes.

Why Is the Bill Controversial?

Supporters argue:

• No more clock changes.
• Better for businesses, tourism, and recreation.
• More evening daylight for families and commuters.

Opponents argue:

• Winter mornings would be much darker, especially in northern states.
• Children could travel to school before sunrise.
• Sleep and health experts often favor permanent standard time, saying it aligns better with the body’s natural circadian cycle.

Has the U.S. Tried This Before?

Yes. During the 1973–74 energy crisis, the U.S. adopted year-round daylight saving time. Public support was initially strong, but it declined after people experienced very dark winter mornings. Congress repealed the policy within a year and returned to seasonal clock changes.

How Could Permanent DST Affect Travel and Businesses?

If permanent Daylight Saving Time (Permanent DST) is approved, it could significantly impact international flight schedules, as airlines would need to adjust departure and arrival times across different time zones. Business meetings across time zones, broadcast schedules, global financial markets, and software systems that rely on time-zone rules would also require updates.

Airlines, technology companies, and other industries would need time to modify schedules and systems before permanent DST is fully implemented.

Frequently Asked Questions

Is permanent DST already in effect?
No. The bill has passed the House but still requires Senate approval and the President’s signature.

Will every U.S. state follow permanent DST?
No. Hawaii, most of Arizona, and several U.S. territories already remain on standard time year-round and are generally exempt.

Why do some doctors oppose permanent DST?
Many sleep specialists say permanent standard time better matches human biological clocks and may support healthier sleep patterns.

When could the change happen?
There is no implementation date yet because the bill has not completed the legislative process. It must first pass the Senate and be signed into law.
