3am EST is 12:00 am PST
3am EDT is 12:00 am PDT in Pacific Time. PST is 3 hours behind EST today, and that gap changes during the year, so this is recomputed rather than assumed.
What time is 3am EST in PST?
It is 12:00 am. Pacific is 3 hours behind Eastern, so you subtract 3 hours from 3:00 am and the date does not change. 3am is the small hours in Eastern, the deadest part of the night, while 12:00 am is midnight in Pacific, the moment the date rolls over.
By the time it is 3am in Eastern, 12.5% of that calendar day has gone. In Pacific the same instant is 0.0% through the same day, which is the clearest way to see what the 3 hours gap actually does.
3am EST to PST 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 EST a good time to call PST?
No. 12:00 am in Pacific is midnight, the moment the date rolls over. Nobody is taking that call. The zones are 3 hours apart, so the nearest sensible slot is a different hour entirely.
Does daylight saving change 3am EST to PST?
Yes. Sampled at 3am on every day of 2026, the gap takes 3 different values. Today it is 3 hours, which is why the answer above is dated rather than fixed.
Eastern Time is currently on EDT 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-4 to UTC-5.
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.
3am PST to EST, 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 PST is 6:00 am EST, which is a different reading from the answer above, because the two directions are separate questions. One wrinkle worth knowing: EST and EDT are two names for the same zone, not two zones. Eastern Time reads EST in winter and EDT in summer. When somebody types "est to pst" they nearly always mean the zone rather than the literal winter offset, so this page resolves EST to America/New_York and PST to America/Los_Angeles and applies whichever offset is genuinely in force on the day.
