East Coast professionals working with West Coast partners check this conversion constantly. Sales teams in New York calling prospects in San Francisco, or product managers in Boston syncing with engineers in Seattle, need to avoid early-morning disruptions on the Pacific side.

Eastern Time is 3 hours ahead of Pacific. A 9 AM call in New York is 6 AM in Los Angeles — far too early for most. End-of-day on the East Coast at 5 PM translates to 2 PM Pacific, leaving plenty of West Coast afternoon remaining.

Because both zones follow the same US Daylight Saving Time schedule, the 3-hour difference never shifts. There is no period of the year where the gap becomes 2 or 4 hours.

Daylight Saving Time: What Changes

Both EST and PST observe daylight saving time. Since they typically switch on the same schedule, the 3-hour difference stays constant year-round — except during the brief transition windows when one zone has switched and the other hasn't yet. During those 1-2 weeks, the offset shifts by one hour.

Frequently Asked Questions

How do I convert EST to PST quickly?

Subtract 3 hours from Eastern Time. If it is 2 PM EST, it is 11 AM PST. This rule applies in both standard time and daylight saving time.

Is there ever a time of year when EST and PST are not 3 hours apart?

No. The US sets a uniform DST schedule for both zones. They spring forward and fall back on the same dates, so the offset is always exactly 3 hours.

If I have a 5 PM deadline EST, when does that fall in Pacific Time?

A 5 PM EST deadline is 2 PM PST. If you are on the West Coast, you have until 2 PM local time to meet an Eastern deadline set at 5 PM.
