PST to EST Converter – Convert Pacific Time to Eastern Time

EST (Eastern Standard Time) is 3 hours ahead of PST (Pacific Standard Time) year-round.

Key conversion examples:

• 00:00 PST = 03:00 EST
• 09:00 PST = 12:00 EST
• 12:00 PST = 15:00 EST
• 18:00 PST = 21:00 EST

This constant 3-hour offset remains the same throughout the year because both time zones observe DST simultaneously. Both switch between standard time (PST/EST, November-March) and daylight time (PDT/EDT, March-November) on the same dates.

To convert PST to EST: Simply add 3 hours to PST time year-round.

Example conversions:

• 09:00 PST = 12:00 EST
• 12:00 PST = 15:00 EST
• 18:00 PST = 21:00 EST
• 22:00 PST = 01:00 EST (+1 day)

The 3-hour difference remains constant because both time zones observe DST on the same schedule. Use our converter above for instant conversions across any date.

Optimal meeting window: 09:00-13:00 PST = 12:00-16:00 EST

This window works best because:

• For US West Coast: Mid-morning to early afternoon (core business hours)
• For US East Coast: Noon to mid-afternoon (core business hours)
• Sweet spot: 10:00 PST = 13:00 EST works perfectly for cross-country teams

This provides comfortable working hours for both Los Angeles and New York teams without requiring early mornings or late evenings for either coast.

No, the PST to EST time difference remains constant at 3 hours year-round.

Here's why:

• Both US Pacific and US Eastern observe Daylight Saving Time on the exact same dates
• PST becomes PDT and EST becomes EDT simultaneously (mid-March)
• Both revert back on the same date (early November)
• The 3-hour offset is maintained throughout all transitions

This synchronized DST schedule makes PST/EST conversion the simplest among US time zones.

Major cities in PST/PDT (UTC-8/-7):

• Los Angeles, CA - 3.9 million (Entertainment capital)
• San Francisco, CA - 815K (Tech hub)
• San Diego, CA - 1.4 million (Biotech center)
• Seattle, WA - 749K (Tech & aerospace)
• Portland, OR - 653K (Manufacturing)
• Las Vegas, NV - 656K (Entertainment)
• Vancouver, Canada - 675K (International gateway)

These cities switch between PST (winter, UTC-8) and PDT (summer, UTC-7) but always remain 3 hours behind EST/EDT.

Major cities in EST/EDT (UTC-5/-4):

• New York, NY - 8.3 million (Financial capital)
• Philadelphia, PA - 1.6 million (Historic city)
• Washington, DC - 712K (US capital)
• Boston, MA - 675K (Education & tech)
• Atlanta, GA - 499K (Transportation hub)
• Miami, FL - 449K (International gateway)
• Toronto, Canada - 2.9 million (Canadian financial center)

These cities switch between EST (winter, UTC-5) and EDT (summer, UTC-4) but always remain 3 hours ahead of PST/PDT.

Best practices for cross-country US scheduling:

1. Optimal window: 09:00-13:00 PST (12:00-16:00 EST)
2. Always specify both time zones in meeting invites (e.g., "10:00 PST / 13:00 EST")
3. Remember the constant 3-hour difference - it never changes
4. Sweet spot: 10:00 PST = 13:00 EST for balanced meeting times
5. DST synchronization: Both coasts change DST simultaneously, maintaining the offset

Popular meeting times: 10:00 PST = 13:00 EST (early afternoon both coasts), 11:00 PST = 14:00 EST (mid-day coordination), 12:00 PST = 15:00 EST (afternoon check-ins).
