EST to PST Converter – Convert Eastern Time to Pacific Time

PST is 3 hours behind EST, so to convert mentally, subtract 3 hours to your EST time. For example: 9:00 AM EST = 6:00 AM PST. Our converter automatically adjusts for Daylight Saving Time so you always get the right result.

PST (Pacific Standard Time, UTC-8) is 3 hours behind EST (Eastern Standard Time, UTC-5) during standard time. For example, 9:00 AM EST = 6:00 AM PST. During DST periods, this difference changes by 1 hour when one or both zones observe Daylight Saving Time — our converter automatically applies the correct offset for any date you select.

The best overlap for standard business hours (9 AM–5 PM) in both zones is 12:00–17:00 EST = 09:00–14:00 PST. Schedule recurring calls in this window to keep both sides within normal working hours. Remember to re-check the window in March and November (or March/October for European zones) when DST transitions can shift the overlap by 1 hour.

Double-check around March and November (or March/October for European zones) when DST transitions can shift the offset by 1 hour.
