The Sunshine Protection Act: Will the US End DST?
The US House voted 308-117 on July 14, 2026, to end the twice-yearly clock change and make daylight saving time permanent, nationwide. If you scroll social media, you'd think it already happened. It hasn't. The bill is sitting in the Senate, and as of late September 2026, nobody in Washington can tell you exactly when, or whether, that changes.
Here's what actually passed, what's stuck, and what it would mean for anyone scheduling calls or converting time zones once (if) it becomes law.
What the Bill Actually Does
The Sunshine Protection Act (H.R. 139, formally the "Sunshine Protection Act of 2025") does one specific thing: it locks the clock on the daylight saving schedule, not standard time. That's a meaningful distinction most headlines skip.
Under the bill, the US would stop "falling back" every November. The spring-forward schedule, the one that currently runs March through November, becomes the permanent, year-round setting. States would still be allowed to opt out and stay on standard time instead, the way Arizona and Hawaii already do today.
FACT: If passed as written, most of the US shifts to what's currently called daylight time, year-round, with no more twice-a-year clock change.
CONTEXT: That means darker mornings in winter, but lighter evenings. A city like Chicago, sunrise around 7:11 AM in mid-December under standard time, would see sunrise closer to 8:11 AM under permanent daylight time. Evening light stretches later instead.
Why the Senate Is the Actual Holdup
The House vote looked decisive. The Senate is where this has died before, and where it's stuck again.
A nearly identical version of this bill actually passed the Senate first, back in March 2022, by unanimous consent. Then it went to the House and never got a vote before that Congress ended, according to the bill's own history on Congress.gov. This time, the order reversed: the House passed it, and it's the Senate holding things up.
The reason isn't procedural inertia. Senators are genuinely split three ways: some want permanent daylight time (this bill), some want permanent standard time instead (citing health research on darker winter mornings and safety), and some are fine leaving the twice-yearly switch alone. President Trump has publicly urged the Senate to move on the bill "as soon as possible," but public pressure from the White House hasn't broken the deadlock yet.
📊 The House passed the Sunshine Protection Act 308-117 in July 2026 — a wide bipartisan margin that hasn't translated into Senate movement even two months later, per The Hill's coverage of the Senate standoff.
The Permanent-Daylight vs. Permanent-Standard Fight, in Plain Terms
This is the part most coverage glosses over: "stop changing the clocks" isn't one position. It's two, and they disagree.
Permanent daylight time (what this bill does) means later sunrises, especially in winter, but longer evening light. Proponents point to evening safety, later daylight for after-work activity, and business hours that better match Europe.
Permanent standard time (the alternative some senators want) keeps winter mornings brighter, which sleep researchers have generally favored for circadian-health reasons, but means it gets dark by late afternoon in winter for northern states.
The US actually tried permanent daylight time before, in 1974, during an energy crisis. It was reversed after about nine months, once winter sunrises past 8 AM in parts of the country turned public opinion sharply against it. That history is part of why some senators are hesitant to move fast on the same idea a second time.
| Permanent Daylight Time (this bill) | Permanent Standard Time (alternative) | Current system | |
|---|---|---|---|
| Winter sunrise (Chicago, mid-Dec) | ~8:11 AM | ~7:11 AM | ~7:11 AM |
| Winter sunset (Chicago, mid-Dec) | Around 5:20 PM | Around 4:20 PM | Around 4:20 PM |
| Clock changes per year | Zero | Zero | Two |
| Main argument for it | Longer evening daylight, closer alignment with Europe's business hours | Brighter, safer winter mornings, favored by sleep researchers | Familiar, no change needed |
| US track record | Tried in 1974, reversed after ~9 months | Never tried nationwide | Current law since 1966 |
What Changes for Time Zone Math If It Passes
If the Sunshine Protection Act becomes law, here's the practical effect for anyone using a time zone converter:
- The clocks stop moving twice a year in the US. No more March/November transition to track for US-based meetings.
- The gap to countries that still observe seasonal DST gets more complicated, not less, for part of the year. The UK and EU, for instance, would still shift their own clocks twice a year, so the US-UK gap would actually change on a different schedule than it does today, since only one side is moving instead of both.
- Nothing changes immediately. Even if the Senate passes it this year, implementation timelines in past versions of this bill included a delay (commonly proposed as one year) before the switch takes effect, to give the transportation and broadcast industries time to adjust.
The States Already Getting Ahead of This
One detail that rarely makes the national coverage: 19 states, including Florida, Georgia, Colorado, Louisiana, and Texas, have already passed their own legislation to adopt permanent daylight time, contingent on Congress allowing it, according to The Hill's tracking of state-level action. Under current federal law (the Uniform Time Act of 1966), states can opt out of DST entirely and stay on standard time year-round, which is exactly what Arizona and Hawaii do. What states currently can't do on their own is the reverse: opt into permanent daylight time. That requires federal action, which is exactly what the Sunshine Protection Act would unlock.
That's part of why this bill has broader state-level support than the House's 308-117 margin alone suggests. Nineteen states are effectively waiting on Congress to hand them a switch they've already voted to flip.
What to Actually Do Right Now
Nothing, yet, the bill hasn't passed. But it's worth bookmarking this if you schedule across the US and international time zones regularly, since the status could change with very little notice once the Senate does act.
The DST 2026 reference page tracks the current, actual clock-change dates as they stand under existing law. If the Senate moves on this bill, that's where the update will land first, not here. In the meantime, the time zone converter already handles today's real DST rules correctly for both US and international time zones, so your conversions stay accurate regardless of how the political fight in Washington resolves.
Frequently Asked Questions
Has the Sunshine Protection Act become law?
No, not as of late September 2026. It passed the US House 308-117 on July 14, 2026, but has not yet been voted on in the Senate.
What's the difference between this bill and just staying on standard time?
This bill makes the daylight saving schedule permanent, the one currently in effect March through November, meaning later sunrises and later sunsets year-round. Staying on standard time permanently, the option some senators prefer instead, would mean earlier sunrises and earlier sunsets year-round. They're opposite choices, not variations of the same idea.
Can states opt out if this passes?
Yes. The bill preserves the existing right of states to stay on standard time instead, the same option Arizona and Hawaii already use today.
Has the US tried permanent daylight time before?
Yes, briefly, in 1974 during an energy crisis. It was reversed by Congress in October 1974, after about nine months, once dark winter-morning commutes and school-bus safety concerns turned public opinion against it.
