Pacific Time Zone

Pacific Time (PT) is the time zone used by the US West Coast. It switches between Pacific Standard Time (PST, UTC-8) in winter and Pacific Daylight Time (PDT, UTC-7) in summer. It covers California, Washington, Oregon, and Nevada, with major cities including Los Angeles, San Francisco, Seattle, Portland, and Las Vegas.

Pacific Standard Time (PST) is UTC-8 — eight hours behind UTC. During Daylight Saving Time (second Sunday in March to first Sunday in November), the West Coast uses PDT (UTC-7).

States in Pacific Time: California, Nevada (most), Oregon, Washington. Part of Idaho (northern panhandle) also uses Pacific Time. British Columbia in Canada also uses Pacific Time.

Pacific Time (PT) is always 3 hours behind Eastern Time (ET). PST (UTC-8) is 3 hours behind EST (UTC-5), and PDT (UTC-7) is 3 hours behind EDT (UTC-4). Both zones shift simultaneously for DST, keeping the gap at 3 hours year-round.
