California still observes daylight saving time because federal law won’t let the state make daylight saving time permanent on its own, and the state legislature has not been willing to pass the one alternative it can enact without Washington’s help: permanent standard time. Voters cleared the legal underbrush in 2018, but every bill since has died, and the clocks keep moving twice a year.
What Voters Approved in 2018
Proposition 7 passed with roughly 60% support in November 2018. It repealed a 1949 ballot measure that had locked California into seasonal daylight saving time by voter mandate, which meant the legislature had no authority to touch time policy until Prop 7 cleared the way.1California Secretary of State. Proposition 7 Title, Summary, and Analysis
Prop 7 gave the legislature authority, by a two-thirds vote, to change the dates of daylight saving and to adopt year-round daylight saving time if federal law ever permits it. It did not actually change any clocks. It handed the question to Sacramento, and Sacramento has yet to answer.
One distinction gets lost in most summaries of the vote. Prop 7 addressed year-round daylight saving time, the “spring forward” schedule. Year-round standard time, the “fall back” schedule, follows a different legal path and doesn’t require the two-thirds vote, because the federal Uniform Time Act already lets any state opt out of daylight saving through ordinary legislation.2Office of the Law Revision Counsel. 15 USC Chapter 6, Subchapter IX – Standard Time
The Federal Law That Blocks Permanent Daylight Saving Time
The Uniform Time Act of 1966 gives states exactly two choices: observe daylight saving on the federal schedule, running from the second Sunday of March to the first Sunday of November, or opt out and stay on standard time year-round. There is no third option. A state that wants to spring forward and stay there needs Congress to amend federal law first.3U.S. Department of Transportation. Uniform Time
Hawaii and most of Arizona have taken the opt-out path and stay on standard time all year.4U.S. Department of Transportation. Daylight Saving Time But most Prop 7 supporters were thinking about keeping summer evenings long, not winter mornings bright, so California’s political energy has gone toward permanent daylight saving time. That is the one option the state cannot adopt on its own.
The U.S. Department of Transportation oversees time zone boundaries and daylight saving compliance, but it has no authority to repeal or modify the law. Its role is clerical: it enforces the schedule Congress set.
The Sunshine Protection Act and Why Congress Hasn’t Moved
The main federal vehicle for unlocking permanent daylight saving time is the Sunshine Protection Act, which would make the spring-forward schedule permanent across the country. In March 2022, the Senate passed the bill by unanimous consent, surprising some House members. The House never held a vote, and the bill died at the end of that congressional session.5U.S. Congress. S.623 – Sunshine Protection Act of 2021
The holdup wasn’t opposition so much as a three-way split. The House committee chair at the time said he couldn’t build consensus because members divided among permanent daylight saving time, permanent standard time, and leaving the current system alone. The bill has been reintroduced every Congress since. It was filed again in January 2025 as S.29 and referred to the Commerce, Science, and Transportation Committee, where it sat without action.6U.S. Congress.

California isn’t waiting alone. Nineteen states have passed laws adopting permanent daylight saving time contingent on federal approval, including Oregon and Washington. Some of those laws contain coordination triggers; Utah’s 2020 legislation, for instance, only takes effect if at least four other western states pass similar measures. The result is a chicken-and-egg problem where states wait for each other, and everyone waits for Congress.
Why California’s Legislature Can’t Agree Either
Even setting aside the federal barrier, Sacramento has not been able to settle the question of which permanent time to adopt. Every post-Prop 7 bill has died, and the failures trace to the same split that stalled the Sunshine Protection Act.
Assembly Bill 7, introduced in 2019, sought year-round daylight saving time. It died in a Senate committee without a vote.8California Legislative Information.

It passed the state Senate 33-1, then died in the Assembly Rules Committee without a hearing.10LegiScan. CA SB1413 2023-2024 Regular Session In 2025, Senator Roger Niello introduced SB 51 to try permanent standard time again.11California State Senate. SB 51 Analysis – Permanent Standard Time
The two-thirds threshold under Prop 7 makes the daylight-saving path especially steep. Permanent standard time needs only a simple majority, because federal law already allows it. But standard time has a selling problem. Most Californians who voted yes on Prop 7 were thinking about keeping long summer evenings, not about December sunrise times. Legislators who back standard time have to explain why the legally available answer is the one voters weren’t picturing when they voted.
Interstate coordination adds a further reason to hesitate. California does business with Oregon, Washington, Nevada, and Arizona, and a time mismatch creates scheduling problems for companies, transportation networks, and broadcast schedules. No one wants to move first.
Why Permanent Daylight Saving Time Spooks Federal Lawmakers
The caution in Washington isn’t theoretical. The country already tried permanent daylight saving time once and reversed course quickly. In January 1974, President Nixon signed the Emergency Daylight Saving Time Energy Conservation Act, putting the entire country on year-round daylight saving as a response to the oil crisis. Public support started at 79%. By February, it had dropped to 42%.
Winter mornings were the problem. Sunrise in northern cities didn’t arrive until well after 8 a.m. Children were walking to school and waiting at bus stops in the dark. Eight students in Florida died in traffic accidents in the weeks after the switch, and schools in the Washington, D.C., area delayed start times until the sun came up. The Department of Transportation concluded that the policy saved little energy and may have increased gasoline consumption. Congress repealed the experiment in October 1974, cutting a planned two-year trial to ten months.
That history shapes every modern proposal. If California alone adopted year-round daylight saving, Los Angeles would see its latest winter sunrise around 7:59 a.m., which is manageable. The worry is the precedent for states farther north. Portland, Oregon wouldn’t see sunrise until nearly 8:51 a.m. on the darkest days, and Indianapolis would wait past 9:00 a.m. Those projections make federal lawmakers nervous about a nationwide policy, and that nervousness blocks the congressional action California needs.
What Would Have to Change
California has the voter mandate, several legislative attempts on record, and a public that overwhelmingly dislikes switching clocks. What it lacks is a route that doesn’t depend on either Congress acting or the legislature choosing the less popular option.
Permanent daylight saving time remains blocked by federal law. The Sunshine Protection Act has been reintroduced in 2026, but it faces the same fragmented House support that has killed it since 2022. Permanent standard time is legally available to California right now by simple majority vote, but legislators have shown little appetite for a change that doesn’t match what voters thought they were endorsing with Prop 7. SB 51, the latest standard-time bill, was working through committee in 2025 on the same trajectory as the bills before it.
Until Congress passes the Sunshine Protection Act or California’s legislature accepts that permanent standard time is the only option it can implement on its own, the clocks will keep changing every March and November. Nearly everyone agrees the switching should stop. No one in a position to stop it can agree on where to stop it.
