Pacific Time to Eastern Time

Pacific Time is generally 3 hours behind Eastern Time. For example, 9 AM Pacific Time is normally 12 PM Eastern Time. Day to day, PT to ET usually follows that same three-hour gap.

PT means Pacific Time. ET means Eastern Time. In winter those clocks often show PST and EST; in summer they show PDT and EDT. If a meeting invite only says “Pacific” or “Eastern,” pick the meeting date so the result matches what local clocks show that day.

What Is the Time Difference Between PST and EST?

PST is UTC−8. EST is UTC−5. EST is three hours ahead of PST; PST is three hours behind EST. As standard time labels, that difference stays the same all year.

  • PST = UTC−8
  • EST = UTC−5
  • EST = PST + 3 hours
  • PST = EST − 3 hours

Example: 9 AM PST is 12 PM EST. 5 PM PST is 8 PM EST. Subtract three hours to go from EST back to PST.

Most of the US Pacific and Eastern regions change clocks in the same weeks of spring and fall. So everyday Pacific Time to Eastern Time usually stays three hours apart in winter and in summer. What changes is the name on the clock: PST/EST in standard time, PDT/EDT in daylight time.

On a January workday, 9 AM PST is 12 PM EST. On a July workday, 9 AM PDT is 12 PM EDT — still three hours, different names. PST to EST always uses standard time, even in July. Pacific Time to Eastern Time follows the date you enter and shows PDT or EDT when local clocks are on daylight time.

Use Pacific Time to Eastern Time for local time on a given day. Stay with PST to EST when the schedule really means standard time on both coasts.
