PST to EST and EST to PST time converter
PST to EST: Eastern Time is 3 hours ahead of Pacific Time, so 9:00 AM in Los Angeles is 12:00 PM in New York. The same page converts EST to PST (subtract 3 hours): switch the direction in the first field. In summer the zones are PDT and EDT and the gap is still 3 hours.

How it is calculated
PST to EST: add 3 hours
Pacific Time is UTC−8 in winter (PST) and UTC−7 in summer (PDT); Eastern Time is UTC−5 (EST) and UTC−4 (EDT). The gap is 3 hours in winter and in summer (the only exception is a few hours on the two changeover days, see below): 9:00 AM PST = 12:00 PM EST, 6:00 PM PST = 9:00 PM EST, 10:00 PM PST = 1:00 AM EST the next day. EST to PST is the reverse, subtract 3 hours: 12:00 PM EST = 9:00 AM PST, and 1:00 AM EST = 10:00 PM PST the evening before.
EST to PST for a deadline
A 5:00 PM Eastern deadline is 2:00 PM on the West Coast, and 9:00 AM Pacific is already lunch in New York. If you write “PST” in an email in July, readers take it as Pacific Time, which is PDT (UTC−7) at that time of year, not PST. Name the zone neutrally (“Pacific Time”) or enter the date here and use the abbreviation shown in the answer.
Changeover Sundays
The coasts change their clocks at 2:00 AM local time, which is three hours apart in UTC. For those three hours – 11:00 PM Saturday to 2:00 AM Sunday on Pacific clocks – the gap is 4 hours (March) or 2 hours (November). On those days the converter adds a note, and the table below is correct hour by hour.
Market hours
The NYSE opens at 9:30 AM Eastern, which is 6:30 AM Pacific, and closes at 4:00 PM Eastern = 1:00 PM Pacific. Prime-time TV listed as 8 PM Eastern airs at 5 PM Pacific unless it is tape-delayed. For the Central zone see CST to EST; for UTC see UTC to EST.
