UTC to PST Time Zone Converter
UTC to PST converts Coordinated Universal Time into US Pacific Time — the clock for Los Angeles, San Francisco, Seattle, and Vancouver. Pacific runs 8 hours behind UTC in winter and 7 hours behind in summer, because the West Coast shifts to daylight time while UTC never moves. The converter picks the right gap for whatever date you choose.

Daylight saving is applied automatically for the date you pick. Labels like PST/EST name the zone (Pacific/Eastern); the real abbreviation shifts to PDT/EDT during daylight saving, and gmt here means London (GMT in winter, BST in summer) while utc stays fixed.
The time difference
US Pacific Time is always behind UTC, and by the widest margin of the mainland US zones. In winter the gap is 8 hours; in summer it narrows to 7 hours. Pacific springs forward for daylight saving while UTC stays fixed, so the two clocks sit an hour closer together through the warmer months.
A worked example
Take 9:00 AM UTC. On January 15, 2026 that is 1:00 AM in Pacific Time — eight hours behind. On July 15, 2026 the same 9:00 AM UTC becomes 2:00 AM, because Pacific is on daylight time and only seven hours behind. A mid-morning UTC time is the middle of the night on the US West Coast.
Daylight saving & the abbreviation caveat
The slug says "PST," which is really the winter name. From March to November the zone is PDT (Pacific Daylight Time) — locals just say "PT" and don't bother with the difference. UTC never changes. So if the result moves by an hour between winter and summer, that's Pacific switching, not a bug. The converter applies the correct offset for the date you pick.
When you'll use it
Great for joining a Los Angeles or San Francisco call from a UTC schedule, timing a West Coast product launch, catching a live tech keynote, or coordinating with a Pacific team when your systems run on UTC.
Frequently asked questions
How many hours behind UTC is Pacific Time?
Eight hours behind in winter (PST) and seven hours behind in summer (PDT). The clocks move forward in spring, which shrinks the gap by an hour until fall.
What time is 16:00 UTC in Los Angeles?
In winter that's 8:00 AM Pacific; in summer it's 9:00 AM. The exact answer depends on the date, which is why the converter asks for one.
Why does the gap change during the year?
Because Pacific Time observes daylight saving and UTC does not. Pacific springs forward on March 8, 2026, and falls back on November 1, 2026 — those are the days the offset flips between eight and seven hours.
