EST to PST — Eastern to Pacific Time

Pacific Time is 3 hours behind Eastern Time, every day of the year.

The conversion rule

Subtract 3 hours from Eastern Time to get Pacific Time. 12:00 PM EST is 9:00 AM PST. Because both zones switch to daylight saving on the same dates (EDT ↔ PDT), the 3-hour gap never changes.

For calls and meetings across the coasts, the comfortable overlap is 12:00–5:00 PM ET / 9:00 AM–2:00 PM PT — inside normal business hours on both sides. A 9:00 AM ET meeting lands at 6:00 AM PT; avoid it.

Frequently asked questions

Is the EST–PST difference always 3 hours?

Yes. Both zones change clocks on the same two dates each year, so the gap is constant — strictly, EST vs PST and EDT vs PDT are each 3 hours apart.

What is 5 PM EST in PST?

2:00 PM PST — end of the New York business day, mid-afternoon in Los Angeles.

When should I schedule a coast-to-coast call?

Between 12:00 and 5:00 PM Eastern (9:00 AM–2:00 PM Pacific), so neither side is before 9 AM or after 5 PM.
