This PST to UTC converter turns any time in Pacific Standard Time (PST) into Coordinated Universal Time (UTC), using your device clock so daylight saving is applied automatically. UTC is 8 hours ahead of PST when both zones are on standard time, and 7 hours ahead during the summer months when clocks have shifted. PST is UTC−8 (PDT: UTC−7); UTC is UTC+0.
PST covers Los Angeles, San Francisco, Seattle; UTC covers Reykjavik (same clock), servers and aviation. 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 PST and UTC?
UTC is 8 hours ahead of PST on standard time. During daylight saving the gap changes to 7 hours. That comes from the UTC offsets: PST is UTC−8 and UTC is UTC+0. For example, 9 am PST = 5 pm UTC, and in summer 9 am PST = 4 pm UTC.
Is UTC ahead of or behind PST?
UTC is 8 hours ahead of PST, so when it is noon in PST it is 8 pm in UTC. Ahead means the clock there already shows a later time; a call at 5 pm PST lands at 1 am UTC.
Does PST or UTC observe daylight saving time in 2026?
PST switches to PDT (UTC−7) on March 8 and back on November 1 in 2026. UTC keeps UTC+0 all year. 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 PST and UTC?
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 PST = 4 pm UTC and 6 pm PST = 2 am UTC the next day. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use PST and UTC?
PST (Pacific Standard Time) is used in Los Angeles, San Francisco, Seattle, Vancouver. UTC (Coordinated Universal Time) is used in Reykjavik (same clock), servers and aviation. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
