Add 3 hours to Pacific Time to get Eastern Time. 12:00 PM PST is 3:00 PM EST. The coasts move to daylight saving in lockstep (PDT ↔ EDT), so the 3-hour spread is permanent.
The coast-to-coast window runs 9:00 AM–2:00 PM PT / 12:00–5:00 PM ET. West Coast mornings are the meeting zone; by 2:00 PM in San Francisco, New York is packing up.

9:00 AM EST — which is why West Coast finance workers start near 6:30 AM PT, when the New York exchanges open.
Before 2:00 PM Pacific. A 3:00 PM PT invitation reads 6:00 PM in New York, after the Eastern workday has ended.
