EST ↔ PST Time Converter

Pacific Standard Time (PST) is 3h behind of Eastern Standard Time (EST). The offset comes from EST being at UTC-5 / UTC-4 (EDT) and PST at UTC-8 / UTC-7 (PDT). For example, when it is 9:00 AM in New York, it is 6:00 AM in Los Angeles.

To convert EST to PST, subtract 3 hours to the EST time. For instance, 12:00 PM EST becomes 9:00 AM PST. For times that cross midnight, remember to adjust the date accordingly — a "+1 Day" or "-1 Day" note in the converter above flags this automatically. You can also just type directly into the converter fields on this page for instant results.

Pacific Standard Time (PST) is 3h behind of Eastern Standard Time (EST). Put the other way, EST is 3h ahead of PST. If someone in Los Angeles says "let's meet at noon," that translates to 3:00 PM in New York.

Eastern Standard Time (EST) is the standard clock time used in regions including New York, Washington DC, Boston, Atlanta. It runs at UTC-5 / UTC-4 (EDT) relative to Coordinated Universal Time (UTC). It observes Daylight Saving Time, advancing clocks by one hour during summer, so the effective offset changes seasonally.

Pacific Standard Time (PST) is the standard clock time used in regions including Los Angeles, San Francisco, Seattle, Portland. It runs at UTC-8 / UTC-7 (PDT) relative to Coordinated Universal Time (UTC). It observes Daylight Saving Time, so the effective offset can shift by one hour during parts of the year.

The best window for meetings between EST and PST is when standard business hours (9 AM – 6 PM) overlap in both zones. Given that PST is 3h behind of EST, mornings in the earlier zone tend to align with afternoons in the later zone. Refer to the meeting hours table above to find the exact windows that fall within working hours for both sides. Avoid scheduling calls where one side falls before 7 AM or after 9 PM — those hours are shaded in the table.

Simply type a time into the PST field in the bidirectional converter above — it works equally well in both directions and updates the EST result instantly. Alternatively, add 3 hours from the PST time to get the EST equivalent. You can also visit the reverse page: PST to EST converter.

For a few hours in the day, the conversion crosses midnight into the next or previous calendar day. Whenever a converted time crosses midnight, the converter above displays a "+1 Day" or "-1 Day" indicator next to the result. The 24-hour table on this page also shows the day change in the Day column. Always check this when scheduling across these two zones to avoid date confusion in calendar invites.

Eastern Standard Time (EST) is used by cities and regions including: New York, Washington DC, Boston, Atlanta, Miami, Philadelphia, Toronto. The zone covers UTC-5 / UTC-4 (EDT)and shifts during Daylight Saving Time.

Pacific Standard Time (PST) is observed in cities and regions including: Los Angeles, San Francisco, Seattle, Portland, San Diego, Las Vegas, Vancouver. It runs at UTC-8 / UTC-7 (PDT)and may shift during Daylight Saving periods.

Yes. EST observes Daylight Saving Time and shifts clocks by one hour seasonally. PST also observes Daylight Saving Time. When only one zone is in DST, the gap between the two changes by one hour. The live clocks and converter on this page use the IANA timezone database and adjust automatically, so you always see the current accurate offset without needing to track DST manually.
