About PST to EST Time

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

Working days overlap between 09:00 and 15:00 PST, which is 12:00–18:00 in EST. 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

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

  1. Take the PST time you want to convert.
  2. Add 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: PST is −8 in winter and −7 in summer (UTC), EST is −5 in winter and −4 in summer.
