Is permanent DST in Las Vegas actually happening?
No. The bill passed the U.S. Senate in March 2022 by unanimous consent. It has never passed the House of Representatives. No version of the Sunshine Protection Act has been signed into law. Las Vegas is on Pacific Daylight Time (PDT, UTC−7) roughly March through November and Pacific Standard Time (PST, UTC−8) the rest of the year. That is not changing in 2026 or 2027 under current law.
What the Sunshine Protection Act actually proposes
The Sunshine Protection Act would make daylight saving time permanent nationwide. For Las Vegas, that means the city would stay on PDT (UTC−7) every day of the year. The fall-back switch in November would disappear. The spring-forward switch in March would disappear. The IANA zone identifier America/Los_Angeles would still be the zone, but the DST rule embedded in it would become irrelevant: the offset would be fixed at UTC−7.
The bill has been reintroduced in multiple Congresses. It passed the Senate in 2022 but never got a vote in the House. Versions introduced in 2023 and 2025 faced the same wall. The House Energy and Commerce Committee, which has jurisdiction, has not advanced it.
How permanent DST would change Las Vegas winter mornings
The biggest effect would hit winter mornings. Look at the December solstice for Las Vegas: 21 December 2026, sunrise at 06:47 and sunset at 16:29, giving just 9 hours 42 minutes of daylight. Under permanent DST, the clocks would be shifted one hour forward.
A 07:47 sunrise in late December means school children walking to bus stops in the dark. Clark County School District elementary schools start around 09:00, but high schools start as early as 07:00. Under permanent DST, the entire first period of high school happens before the sun comes up.
The trade-off is the evening. An extra hour of daylight after work. For the Strip, for outdoor dining, for the rhythm that defines Las Vegas, that extra hour in the evening matters.
Would permanent DST change Las Vegas summer evenings much?
On the June solstice (21 June 2026), Las Vegas gets 14 hours 37 minutes of daylight. Sunrise at 05:23, sunset at 20:00. The sun would set at 9 PM in June. That is not radically different from what Las Vegas already experiences in July and August, when sunset hovers around 20:00. The change is less dramatic than the winter shift.
Why hasn't permanent DST passed for Las Vegas yet?
The Sunshine Protection Act passed the Senate in March 2022 with no recorded opposition. Senator Marco Rubio has been the primary sponsor. The bill has never reached the House floor. Why? The House Energy and Commerce Committee has heard testimony on both sides. The opposition comes from a coalition of sleep scientists, some school boards, and representatives from northern states who worry about winter mornings that would stay dark until after 9 AM.
The Uniform Time Act of 1966 is the federal law that governs DST. It allows states to exempt themselves from DST (Arizona and Hawaii do), but it does not allow states to make DST permanent on their own. Any state that wants DST all year needs Congress to amend the Uniform Time Act or pass a law authorizing the change.
Does California's Proposition 7 affect permanent DST in Las Vegas?
California voters passed Proposition 7 in 2018 by a 60% margin. The proposition authorized the state legislature to pursue permanent DST, subject to federal approval. The California legislature has not passed the required two-thirds vote to enact it. The bill has been introduced multiple times and died each session.
Why does California matter for Las Vegas? Nevada and California share the same time zone. If California went to permanent DST and Nevada stayed on the current system, Las Vegas would be one hour behind Los Angeles for half the year. That would break broadcast schedules, flight times and the coordinated rhythm of the West Coast. No serious proposal in Nevada has moved forward without California acting first.
What has Nevada tried to do about permanent DST?
The Nevada legislature has considered multiple bills to end DST or switch to a different system. None has passed. Assembly Bill 81 (2019) proposed putting Nevada on standard time all year. Assembly Bill 85 (2021) proposed aligning Nevada with Arizona's approach. Both died in committee.
The practical barrier is the same one California faces: the Uniform Time Act. Nevada cannot make DST permanent without federal permission. It can exempt itself from DST and stay on standard time all year, as Arizona does. It has not done that either.
The Arizona alternative: permanent standard time
Arizona has not observed DST since 1967. Phoenix stays on Mountain Standard Time (UTC−7) all year. In summer, when Las Vegas is on PDT (UTC−7), the two cities share the same clock time. In winter, when Las Vegas falls back to PST (UTC−8), Phoenix is one hour ahead.
If Nevada chose the Arizona path, permanent standard time, Las Vegas would be on UTC−8 all year. The June solstice sunrise would be 05:23. The December solstice sunrise would be 06:47. Summers would start earlier, winters would stay roughly the same. That option requires no federal approval. It requires only a state law. No such law has passed.
What would need to change for permanent DST in Las Vegas?
For Las Vegas to get permanent DST, one of two things must happen:
-
Congress passes the Sunshine Protection Act or an equivalent amendment to the Uniform Time Act, making DST permanent nationwide. The Senate has done its part. The House has not.
-
Congress passes a law allowing states to choose permanent DST individually. No such bill has advanced.
For Las Vegas to get permanent standard time (the Arizona model), the Nevada legislature would need to pass a bill exempting the state from DST. That requires a simple majority vote and the governor's signature. It has not happened.
When could permanent DST in Las Vegas actually happen?
The next clock change in Las Vegas is Sunday 1 November 2026 at 02:00 local, when clocks fall back to PST. The following change is Sunday 14 March 2027 at 02:00 local, when clocks spring forward to PDT.
No federal legislation is currently scheduled for a House vote. The Sunshine Protection Act is not on the House calendar for 2026. The 2026 election cycle makes major time legislation unlikely. The earliest realistic window for any federal action is 2027 or later.
For now, Las Vegas continues the twice-yearly rhythm it has followed since 1966. The next change is the fall-back on 1 November 2026. Set your clocks back one hour. Enjoy the extra hour of sleep. The permanent DST question remains open, stalled in the House, waiting for a vote that has not come.
