How many hours ahead is EST compared to PST?

Eastern Standard Time is 3 hours ahead of Pacific Standard Time year-round. When New York is at noon EST, Los Angeles is at 9 AM PST. This gap holds steady whether or not either coast is observing daylight saving time, because both switch on the same dates.

Do EST and PST change by the same amount for daylight saving?

Yes. Both Eastern and Pacific time zones in the US follow the same daylight saving schedule, springing forward on the second Sunday in March and falling back on the first Sunday in November. Because both shift simultaneously, the 3-hour gap between them never changes.

What is the best overlapping window for meetings between EST and PST?

The most practical window is 12 PM to 5 PM EST (9 AM to 2 PM PST). This keeps Eastern participants within business hours and avoids asking Pacific colleagues to join before 9 AM. The sweet spot is 1–3 PM EST / 10 AM–12 PM PST.
