EST to PST Converter (Eastern Time to Pacific Time)

PST is 3 hours behind EST.

Eastern Time is the clock of New York, Boston, Washington, Atlanta and Miami. Pacific Time is the clock of Los Angeles, San Francisco, San Diego, Seattle, Portland and Las Vegas. Both regions move their clocks on the same dates, from the second Sunday of March to the first Sunday of November, so the gap between them is the same in January and in July.

That makes this the steadiest big pair in the United States: every Eastern hour has a Pacific partner exactly three hours earlier, with no seasonal exception to remember. Most people look it up for a call, a flight arrival or the start of a live broadcast that is quoted in Eastern Time.

How to use this tool

1. Pick a date and time in EST. The date matters when daylight saving time is in force.
2. Read the matching time in PST, with both UTC offsets.
3. Use "Use current time" for now, or the tables below for a quick look.

Formula

PST time = EST time − (EST UTC offset) + (PST UTC offset)

The converter looks up both UTC offsets for the actual instant in the saved IANA time zone rules, so daylight saving changes are included automatically.

Example

Worked with the saved rules:

9:00 AM EST on March 2, 2026 = 6:00 AM PST

6:30 PM EDT on August 3, 2026 = 3:30 PM PDT

Time difference through the year

The difference depends on the date when either place moves its clocks. These are the offsets on two reference days, from the saved IANA rules:

Clock changes in 2026

Between these dates the difference shifts by the size of the change.

Hours that work in both places

Hours (on the January reference day) that fall between 8:00 AM and 8:00 PM in both EST and PST:

Starting a call from the East Coast

The Pacific morning does not begin until the Eastern day is well under way. A 9:00 a.m. meeting in New York is 6:00 a.m. in Los Angeles, which is why East Coast teams that work with California usually move shared meetings to late morning or the afternoon, when both offices are staffed.

Broadcasters handle the gap the other way round. A network that announces prime time at 8 p.m. Eastern usually offers the Pacific audience the same program at 8 p.m. on their own clocks, delayed by three hours, whereas live sport keeps to one moment: a game that starts at 4:30 p.m. Eastern begins at 1:30 p.m. Pacific.

States and cities that sit in between

Two zones lie between these two coasts. Chicago and Houston are one hour behind Eastern Time, and Denver is two hours behind. If a partner works in either place, the Pacific time is only the last step of the chain, so check which of the three clocks a meeting invitation actually uses.

Zone borders do not always follow state borders. Most of Oregon and Idaho's northern panhandle observe Pacific Time, while southern Idaho and a small part of eastern Oregon are on Mountain Time; the federal rule that defines the zone boundaries is in 49 CFR Part 71.
