UTC-8

West Coast hours

UTC-8 is a time zone eight hours behind Coordinated Universal Time.

It covers the Pacific coast of North America during standard time—California, Washington, Oregon, and British Columbia operate on UTC-8 in winter.

When daylight saving shifts these regions to UTC-7, places like Alaska and parts of the Pacific islands remain at UTC-8 year-round.
