New York works three hours ahead of Los Angeles, and that gap shapes everything that crosses the country: meeting invites, market opens, kickoff times, and season premieres. The clocks above show both zones right now, the converter turns any Eastern time into its Pacific equivalent for any date, and the chart lays out all twenty-four hours at once. Everything is computed in your browser from the standard timezone database, so daylight saving is never your problem to remember.
What People Convert EST to PST For
Scheduling coast-to-coast meetings
A 9-to-5 day in New York overlaps a 9-to-5 day in Los Angeles for just five hours: noon to 5 p.m. Eastern, which is 9 a.m. to 2 p.m. Pacific. Book inside that window and nobody joins before breakfast. The shaded cells in the chart mark business hours on both coasts, so a workable slot is visible at a glance.
Market hours from the West Coast
The New York Stock Exchange opens at 9:30 a.m. Eastern, which is 6:30 a.m. in California — a fact of life for every West Coast trader. The closing bell at 4 p.m. Eastern lands at 1 p.m. Pacific, leaving a full afternoon after the close. Futures and pre-market announcements follow the same three-hour shift.
Premieres, drops, and launch times
Streaming platforms, game studios, and record labels often release at midnight Eastern — which is only 9 p.m. Pacific the evening before. In the other direction, a product event that starts at 10 a.m. in Cupertino or Los Angeles begins at 1 p.m. for the East Coast audience. Type the announced time into the converter and the ambiguity is gone.
Live sports across the gap
A 1 p.m. Eastern NFL kickoff is a 10 a.m. start in Los Angeles, and Sunday-night games that begin at 8:20 p.m. Eastern reach the West Coast at a comfortable 5:20 p.m. West Coast night games punish Eastern viewers instead: a 10 p.m. Eastern tip-off in a Lakers series means an after-1-a.m. final buzzer in New York.
Calling family without the guesswork
The three-hour gap has a simple courtesy rule: East Coasters should avoid calling the Pacific side before about 11 a.m. Eastern (8 a.m. Pacific), and Pacific callers should stop dialing east after about 8 p.m. their time (11 p.m. Eastern). The live clocks above settle the question before the phone rings.
Flights and arrival math
A nonstop from JFK to LAX takes a bit over six hours but lands only about three hours later on the clock, because the plane flies with the time change: leave New York at noon, land in Los Angeles around 3 p.m. Pacific. Eastbound red-eyes work the other way, departing late evening and landing mid-morning. Check the chart against your itinerary before promising a pickup time.
How the Conversion Works
The converter does not use a fixed three-hour subtraction. It asks your browser's IANA timezone database for the exact offset of America/New_York and America/Los_Angeles at the specific instant you pick, which means the handful of odd hours around daylight-saving transitions convert correctly too. Both zones change to daylight time on the same spring morning and back on the same fall morning, so the difference is three hours essentially year-round — but the chart earns its keep on those two transition days, and whenever a date far in the past or future is involved. Nothing you type into the converter is sent anywhere; the math runs entirely on your device.
Frequently Asked Questions
Is EST always exactly 3 hours ahead of PST?
For practical purposes, yes. Both the Eastern and Pacific zones switch to daylight saving on the same dates, so the gap stays three hours through the year. Strictly speaking, in summer the zones are called EDT and PDT — most people keep saying EST and PST, and this page follows the zones themselves, so the conversion is right either way.
What is 9 a.m. EST in PST?
9 a.m. Eastern is 6 a.m. Pacific. The rule of thumb is subtract three hours going east-to-west. Going the other way, add three: 9 a.m. Pacific is noon Eastern. The chart above lists all twenty-four hours if you'd rather look it up than do arithmetic.
When is the best time for an EST–PST meeting?
The five-hour overlap of standard business days runs from noon to 5 p.m. Eastern (9 a.m. to 2 p.m. Pacific). Mid-window — around 1 to 3 p.m. Eastern — avoids the Pacific early-morning scramble and the Eastern end-of-day rush, which is why so many coast-to-coast standing calls settle there.
Why does my calendar say EDT instead of EST?
EDT is Eastern Daylight Time, the summer form of Eastern Time, one hour ahead of winter's EST. Calendar apps display whichever is in force on the meeting date. Searchers say "EST" year-round as shorthand for Eastern Time, and this converter handles the seasonal switch automatically, so the result is correct in any month.
Is all of California on PST?
California, Washington, and Nevada sit in the Pacific zone, along with most of Oregon and a corner of Idaho. Do not confuse it with Arizona: most of Arizona stays on Mountain Standard Time all year and skips daylight saving, which makes it match Pacific Daylight Time in summer only — a classic scheduling trap.
Do EST and PST ever briefly differ by a different amount?
Only inside the daylight-saving changeover itself. The clocks switch at 2 a.m. local time in each zone, and since 2 a.m. arrives in New York three hours before Los Angeles, there is a short early-morning window twice a year when the gap reads two or four hours. The converter follows the database, so even those hours come out right.
