What PST and UTC Actually Are
PST — Pacific Standard Time
Los Angeles, San Francisco, Seattle, Las Vegas, Vancouver. Standing at UTC-8:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to PST. The Philippines occasionally uses PST for Philippine Standard Time (UTC+8); PHT is the clearer label for that.
California voted in 2018 to move to permanent daylight time, but the change needs an act of Congress and has never happened, so PST is still the winter standard.
UTC — Coordinated Universal Time
The global reference standard. Aviation, computing and science run on it. Standing at UTC as written, and the region does not change its clocks, so that offset holds all year.
UTC is not a place. It is a computed standard, kept within a second of mean solar time at Greenwich by atomic clocks, and it is the reference every other zone is defined against.
What This Means in Practice
This gap is not fixed
PST changes its clocks and UTC does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.

Frequently Asked Questions
What is the time difference between PST and UTC?
UTC is 7 hours ahead of PST. That is the live figure. Taken strictly as written, the gap between PST and UTC is 8 hours — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM PST in UTC?
9:00 AM PST is 4:00 PM UTC.
What are the best hours to schedule a call between PST and UTC?
Between 9:00 AM and 10:00 AM PST, which is 4:00 PM to 5:00 PM UTC. Both sides are inside normal business hours through that window.
Does the difference between PST and UTC change during the year?
Yes. PST observes daylight saving and UTC does not, so the gap shifts by an hour at least twice a year. The next clock change is on Sunday, November 1, 2026.
Does PST always mean Pacific Standard Time?
The Philippines occasionally uses PST for Philippine Standard Time (UTC+8); PHT is the clearer label for that.
