Time zones in California
| Zone | IANA | Standard | Daylight | Abbr |
|---|---|---|---|---|
| Pacific Time | America/Los_Angeles | UTC−8 | UTC−7 | PST / PDT |
California is Pacific Time statewide (PST/PDT, UTC−8 in winter, UTC−7 in summer), with no Mountain areas; Los Angeles, San Francisco, and San Diego all follow the same clock.
Crossing the state line
California shares Pacific Time with Oregon and Nevada. Its southeastern neighbor Arizona skips daylight saving, so Arizona matches California’s clock from March to November and is one hour ahead in winter. Baja California, across the Mexican border, keeps the same clock and daylight-saving dates as California.
