What Prop 7 actually allows (and doesn't)

Roughly 60 percent of voters backed Proposition 7 in November 2018. The ballot measure asked one question: should the state legislature have the authority to pursue permanent daylight saving time? It was not a direct vote to end clock changes. It was permission.

Prop 7 passed. The legislature has not acted.

That is the single most important fact about permanent DST in the Pacific zone: voters approved it, and nothing happened. The state legislature has introduced bills but never passed one. The reason is not Sacramento politics. It is national law.

Proposition 7 gives lawmakers in California the authority to change state law so that the state observes daylight saving time year-round. But the Uniform Time Act of 1966 says states cannot set permanent DST on their own. They can opt out of DST entirely and stay on standard time year-round (Arizona and Hawaii do this). They cannot opt into permanent DST without an act of Congress.

So Prop 7 was always conditional. The nation's most populous state said yes to a change that requires Washington approval. No approval has been granted.

The legislature could pass a bill tomorrow. It would take effect only when lawmakers on Capitol Hill change national law. That is why Sacramento has not rushed.

The Sunshine Protection Act: national status

The Sunshine Protection Act is the bill that would make daylight saving time permanent nationwide. It passed the US Senate in March 2022 by unanimous consent. It stalled in the House of Representatives and never became law.

As of September 2026, the Sunshine Protection Act has been reintroduced but not passed. The bill would move the entire US to permanent DST, meaning Pacific Time would shift to UTC−7 year-round. Clocks would never fall back to PST (UTC−8).

The bill has bipartisan support and bipartisan opposition. Sleep scientists oppose it. Some conservative members oppose it. The House has not brought it to a vote.

Will British Columbia ever stop changing its clocks?

British Columbia passed its own permanent DST law in 2019. The law is contingent: it takes effect only when Washington, Oregon, and California also adopt permanent DST, and when the US federal government approves the change.

BC is waiting. The province cannot move alone. If it did, Vancouver would be on a different time than Seattle for half the year. That would disrupt cross-border trade, commuting, and broadcasting. So BC waits with its legislation ready.

Why the whole West Coast is stuck waiting

Oregon passed a permanent DST bill in 2019. Washington passed one in 2019. Both are contingent on California acting first and national law changing.

The Pacific Northwest cannot go alone either. If Oregon and Washington switched but the state to their south did not, Portland and Seattle would be an hour ahead of San Francisco and Los Angeles for half the year. That would break Pacific Time as a region.

So the entire West Coast is in a holding pattern. One state has not passed a law. Congress has not passed a law. No one moves until both happen.

Permanent DST vs permanent standard time: the science debate

The sleep science community is clear: permanent standard time is healthier than permanent DST. The American Academy of Sleep Medicine, the American Sleep Research Society, and other medical organizations support permanent standard time.

The reason is sunlight. Under permanent DST, winter sunrises would be later. The human circadian clock responds to morning light. Delaying sunrise means more people wake in darkness, which is linked to reduced alertness, higher accident rates, and poorer health outcomes.

The 1974 permanent DST trial under President Nixon is the real-world evidence. The US tried year-round DST from January 1974 to October 1975. It was deeply unpopular. Parents complained about sending children to school in darkness. The trial ended early.

Supporters of permanent DST point to evening light. Longer daylight in the afternoon and evening reduces crime, boosts retail sales, and gives people more time for outdoor recreation after work. The tradeoff is darker mornings.

What would change if Pacific Time went permanent DST

If permanent DST took effect, Pacific Time would stay on PDT (UTC−7) year-round. There would be no spring forward in March and no fall back in November.

Here is what that means for specific dates in Los Angeles:

The day would still be 9 hours 53 minutes long, but the light would be pushed an hour later.

The effects are more extreme the farther north you go. Vancouver would see similar shifts.

Business hours would not change. Stock markets would still open at 06:30 PT. School start times would not shift. The change would be invisible indoors. The difference is outdoor light timing.

Timeline: when could this actually happen?

There is no timeline. The Sunshine Protection Act has not passed. California has not acted. The earliest realistic date is 2028 or later, and only if Congress passes a bill and the state passes a law in the same session.

Realistically, the most likely outcome is no change. The US has not successfully switched to permanent DST since the failed 1974 trial. The political coalition for change is broad but shallow. The opposition from sleep scientists and from members who prefer permanent standard time is stronger than it looks.

If you want permanent standard time instead, that is simpler legally. States can opt out of DST without Washington approval. Arizona and Hawaii did it. But no Pacific Time state has shown interest in that direction.
