EST to PST Converter

Pacific Time is 3 hours behind Eastern Time all year: EST to PST in winter, EDT to PDT in summer. The gap stays the same because both coasts change clocks on the same dates.

Daylight saving note: Eastern Time and Pacific Time switch to daylight saving on the same dates, so the East Coast and West Coast stay 3 hours apart all year: EST to PST in winter, EDT to PDT in summer.

Best Hours to Schedule Eastern Standard Time–Pacific Standard Time Calls

The practical overlap for US coast-to-coast calls is 12:00–5:00 PM Eastern (9:00 AM–2:00 PM Pacific), in winter and summer alike. Scheduling before noon Eastern means a pre-9 AM call for West Coast colleagues; a 12:00–1:00 PM Eastern standup lands at 9:00–10:00 AM Pacific.

About Eastern Standard Time (EST/EDT)

Eastern Time (EST/EDT) is the US East Coast timezone. New York, Boston, Philadelphia, and Miami all use it. It uses EST (UTC-5) in winter and EDT (UTC-4) in summer, switching on the same Sundays in March and November as Pacific Time, which is why the East-West gap stays at 3 hours.

About Pacific Standard Time (PST/PDT)

Pacific Time (PST/PDT) covers the US West Coast — California, Oregon, and Washington state. It is the furthest behind of the four main continental US time zones, using PST (UTC-8) in winter and PDT (UTC-7) in summer. Silicon Valley, Hollywood, and Seattle all run on Pacific Time.

How to Avoid Eastern Standard Time–Pacific Standard Time Conversion Mistakes

Before 3:00 AM EST/EDT, Pacific Standard Time is still on the previous calendar day. For example, 12:00 AM EST/EDT is 9:00 PM in Pacific Standard Time on the previous day (EST/EDT → PST/PDT).

Abbreviations can be ambiguous here: Eastern Standard Time switches between EST and EDT across the year, while Pacific Standard Time switches between PST and PDT. City names and IANA time zones (America/New_York and America/Los_Angeles) are safer for exact scheduling if you're automating anything, since they resolve the right abbreviation automatically instead of needing a manual seasonal check.

Worked Example: A Noon Eastern Webinar and a Midnight Deadline

Say you host a webinar at 12:00 PM Eastern. That's 9:00 AM Pacific, so West Coast attendees join at 9:00 AM. Move it to 3:00 PM Eastern and it's 12:00 PM Pacific. The three hour gap is the same all year, because both coasts move their clocks on the same dates.

Deadlines are less forgiving than meetings. "Midnight Eastern" is 9:00 PM the previous day in Pacific Time, so someone in Los Angeles who thinks they have until the end of their own day is three hours too late. State the zone, and if it matters, the Pacific time too.

From the Pacific side, add three hours. A 9:00 AM start in Pacific Time is 12:00 PM Eastern, and 4:00 PM is 7:00 PM. If you're scheduling with East Coast teams, the Pacific morning is where the overlap lives, so book early.

Frequently Asked Questions

Does the EST to PST difference change for daylight saving?

No. Both Eastern and Pacific Time observe US Daylight Saving Time on the same Sunday in March and November. Eastern Time shifts to EDT (+1h) and Pacific Time shifts to PDT (+1h) simultaneously, so the 3-hour gap is constant.

What time is 9 AM EST in PST?

9:00 AM EST is 6:00 AM PST, and in summer 9:00 AM EDT is likewise 6:00 AM PDT. A 9:00 AM East Coast meeting means a 6:00 AM start on the West Coast.

What is the best time for an EST-PST meeting?

The best US coast-to-coast meeting window is 12:00–3:00 PM Eastern (9:00 AM–12:00 PM Pacific), in both winter and summer. Both sides are in normal business hours. Avoid anything before noon Eastern for calls with West Coast colleagues.

What US states use PST?

Pacific Time covers California and Washington, most of Nevada and Oregon, and northern Idaho. These areas use PST (UTC-8) in winter and switch to PDT (UTC-7) for daylight saving time. Eastern Time states include New York, Georgia, Pennsylvania, and most of Florida.
