About EST to PST Time

EST covers New York, Toronto, Atlanta, Miami and Boston. PST covers Los Angeles, San Francisco, Seattle, Las Vegas and Vancouver.

Working days overlap between 12:00 and 18:00 EST, which is 09:00–15:00 in PST. That window is where calls land without anyone working late.

Both regions use daylight saving, so the gap holds for most of the year — except for the week or two each spring and autumn when they switch on different dates.

How it works

Pacific Time (Los Angeles) is always 3 hours behind of Eastern Time (New York).

  1. Take the EST time you want to convert.
  2. Subtract 3 hours.
  3. Roll the date forward or back if the result crosses midnight.

Neither side changes its clocks relative to the other, so this gap holds all year.

Zone details: EST is −5 in winter and −4 in summer (UTC), PST is −8 in winter and −7 in summer.
