EST to Pacific Time Converter

EST to Pacific Time Hour Table

The table below converts every hour of the day between Eastern Time and Pacific Time. The row highlighted in blue is the current hour in Eastern Time.

How to Convert EST to Pacific Time

To convert Eastern Time to Pacific Time, subtract 3 hours. 3:00 PM EST becomes 12:00 PM PST; 9:00 AM EST becomes 6:00 AM PST. Going the other way, add 3 hours — noon in Los Angeles is 3:00 PM in New York.

The one thing to watch is the day boundary. Between 12:00 AM and 2:59 AM Eastern, the Pacific clock is still on the previous calendar day: 1:00 AM EST on Saturday is 10:00 PM PST on Friday. The table above marks those rows “previous day” for that reason, and the date picker carries the correct date when you convert them.

No daylight saving adjustment is needed on your side. Both zones change on the same dates, so the 3-hour difference applies in March through November exactly as it does in winter.

About These Time Zones

Eastern Time is UTC−5 during standard time (EST) and UTC−4 during daylight saving time (EDT). Pacific Time is UTC−8 during standard time (PST) and UTC−7 during daylight saving time (PDT). Both zones switch on the same dates under US rules, so the difference between them never changes across the year — it is always 3 hours.

Why the Difference Stays 3 Hours All Year

Both zones switch on the same dates under US daylight saving rules — the second Sunday in March and the first Sunday in November. Because they change together, the gap between them never moves: Eastern Time is 3 hours ahead of Pacific Time all year, whether you are comparing EST with PST or EDT with PDT.

That is the practical difference between a fixed abbreviation and a general zone name. EST always means UTC−5, but "Eastern Time" becomes EDT in summer. If a source quotes a different offset, it is usually mixing standard-time and daylight-time labels.

Scheduling Across EST and Pacific

Because the gap is a constant 3 hours, the working overlap between the two zones runs roughly from 12:00 PM to 8:00 PM Eastern — that is 9:00 AM to 5:00 PM Pacific. A 3:00 PM call in New York is noon in Los Angeles; a 9:00 AM meeting in California means a noon start for the East Coast.

Common Use Cases

Remote teams: standups and handoffs are easiest between 9:00 AM and 12:00 PM Pacific, when both coasts are on the clock.

Client calls and sales: a 3:00 PM slot in New York is noon in Los Angeles — the most common compromise across US time zones.

Travel and flights: airline schedules print local departure and arrival times, so converting them means comparing two different offsets at two different moments.

Cities in Each Time Zone

Eastern Time covers the eastern seaboard and the industrial Midwest: New York, Washington, Boston, Philadelphia, Atlanta, Miami, Detroit and Charlotte, plus Toronto and Montreal in Canada. It is the most populous time zone in the United States.

Pacific Time covers the west coast: Los Angeles, San Francisco, Seattle, Portland, San Diego, Las Vegas and Sacramento, plus Vancouver in Canada.

Arizona is the exception worth remembering. The state stays on Mountain Standard Time all year and does not observe daylight saving, so Phoenix matches California’s clock in summer but sits one hour ahead of it in winter. A conversion that assumes “Mountain” is always one hour behind Pacific will be wrong for Arizona for half the year.

Eastern Time vs the Other US Zones

Pacific Time is not the only zone Eastern businesses convert to. The offsets below hold all year, because every zone on this list follows the same daylight saving schedule.

Note the exception again: Arizona keeps Mountain Standard Time year-round, so in summer Phoenix is 3 hours behind New York rather than 2. Each pair has its own converter — the related links below cover them.
