This UTC to PST converter turns any time in Coordinated Universal Time (UTC) into Pacific Standard Time (PST), using your device clock so daylight saving is applied automatically. PST is 8 hours behind UTC when both zones are on standard time, and 7 hours behind during the summer months when clocks have shifted. UTC is UTC+0; PST is UTC−8 (PDT: UTC−7).
UTC covers Reykjavik (same clock), servers and aviation; PST covers Los Angeles, San Francisco, Seattle. Because only PST observes daylight saving time, the difference is not constant through the year. The tables below show both cases, and the converter at the top always uses the rule in force on the date you pick.

Frequently asked questions
What is the time difference between UTC and PST?
PST is 8 hours behind UTC on standard time. During daylight saving the gap changes to 7 hours. That comes from the UTC offsets: UTC is UTC+0 and PST is UTC−8. For example, 9 am UTC = 1 am PST, and in summer 9 am UTC = 2 am PST.
Is PST ahead of or behind UTC?
PST is 8 hours behind UTC, so when it is noon in UTC it is 4 am in PST. Ahead means the clock there already shows a later time; a call at 5 pm UTC lands at 9 am PST.
Does UTC or PST observe daylight saving time in 2026?
UTC keeps UTC+0 all year. PST switches to PDT (UTC−7) on March 8 and back on November 1. Between those dates the difference in the table above shifts by an hour, which is the usual cause of missed calls in spring and autumn.
What is the best time for a meeting between UTC and PST?
Office hours (9 am to 5 pm) do not overlap at all with a 8 hours difference. The least painful options are early morning in PST or early evening in UTC; for example 8 am UTC = 12 am PST and 6 pm UTC = 10 am PST. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use UTC and PST?
UTC (Coordinated Universal Time) is used in Reykjavik (same clock), servers and aviation. PST (Pacific Standard Time) is used in Los Angeles, San Francisco, Seattle, Vancouver. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
