Questions

What time zone is California in?

California is entirely in Pacific Time. All 58 counties in this outline use that clock.

Which California counties are split between time zones?

No California county came back with two different clocks in the sample. A city on the legal line can still differ from its county.

Does California observe daylight saving time?

California observes daylight saving time on the federal schedule: the second Sunday in March until the first Sunday in November.

Estimates only

County colors come from an interior sample of Census outlines against timezone-boundary-builder. 49 CFR Part 71 is the legal description, including towns that sit on the line.
