California Uses Pacific Time California is a single-zone state. Los Angeles, San Diego, San Francisco, Sacramento, San Jose and the rest of the state share one official clock. PST Means UTC−08:00

America/Los_Angeles Carries the Rules The IANA location zone stores California’s historical and seasonal Pacific Time transitions so software can calculate the right offset for a date. Same Clock, Different Zone Rules During California’s PDT period, both California and most of Arizona are UTC−07:00. In California’s PST period, California becomes one hour behind most of Arizona. Proposition 7 Did Not End Clock Changes California voters gave the Legislature authority to change DST under specified conditions, but the current seasonal schedule remains in effect. Why California and Arizona Can Show the Same Time California and most of Arizona use different time-zone rules, even when their clocks happen to match. Most of Arizona stays on Mountain Standard Time at UTC−07:00 all year. California is UTC−07:00 only while it is on Pacific Daylight Time. Did Proposition 7 End Daylight Saving Time in California? No. California Proposition 7, approved in 2018, allowed the Legislature—with a two-thirds vote—to change the state’s daylight-saving period when the change is consistent with federal law. The Legislative Analyst’s Office stated that absent a valid legislative change, California would maintain the current seasonal DST period. California therefore continues to switch between PST and PDT under the current rules. A vote to study or authorize future changes is not the same as an enacted permanent-time rule.
