3 PM Eastern Standard Time is 12 PM (noon) in California (Pacific Time), when both places are on standard time and not on different daylight saving schedules.

If you’re writing it out for clarity, you can say:

  • 3:00 PM EST = 12:00 PM PST (California).

Always double-check the date if it’s around the start or end of daylight saving time, since EST is a fixed standard-time zone while California usually switches between PST and PDT.
