3am PST is 10:00 am UTC
3am PDT is 10:00 am UTC in Coordinated Universal Time. UTC is 7 hours ahead of PST today, and that gap changes during the year, so this is recomputed rather than assumed.
What time is 3am PST in UTC?
It is 10:00 am. UTC is 7 hours ahead of Pacific, so you add 7 hours to 3:00 am and the date does not change. 3am is the small hours in Pacific, the deadest part of the night, while 10:00 am is mid morning in UTC, the busiest stretch of the working morning.
By the time it is 3am in Pacific, 12.5% of that calendar day has gone. In UTC the same instant is 41.7% through the same day, which is the clearest way to see what the 7 hours gap actually does.
3am PST to UTC in the hours either side
The four hours before and after 3am, in case the meeting moves. Note that the calendar date does not stay put across this window: it changes partway through, which is exactly where scheduling mistakes come from.

Is 3am PST a good time to call UTC?
It works for them, not obviously for you. 10:00 am is a normal working hour in UTC, but 3am is the small hours in Pacific, the deadest part of the night. Expect to be the one making the compromise.
Does daylight saving change 3am PST to UTC?
Yes. Sampled at 3am on every day of 2026, the gap takes 2 different values. Today it is 7 hours, which is why the answer above is dated rather than fixed.
Pacific Time is currently on PDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-7 to UTC-8.
Coordinated Universal Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
3am UTC to PST, the other way round
Running the question the other way is a different conversion, not a mirror image, because the two zones can be in different daylight saving states on the same date. 3am UTC is 8:00 pm PST, the previous day, which is a different reading from the answer above, because the two directions are separate questions. One wrinkle worth knowing: PST and PDT are two names for the same zone, not two zones. Pacific Time reads PST in winter and PDT in summer. When somebody types "pst to utc" they nearly always mean the zone rather than the literal winter offset, so this page resolves PST to America/Los_Angeles and UTC to Etc/UTC and applies whichever offset is genuinely in force on the day.
