What this does
Enter a time on the US West Coast (Pacific) and read off the matching East Coast (Eastern) time. Eastern is always 3 hours ahead of Pacific, so 9:00 AM in California is 12:00 PM noon in New York.
Why is it always 3 hours, even during daylight saving?
Because both coasts observe daylight saving at the same time. In winter it's PST (UTC−8) and EST (UTC−5); in summer both spring forward to PDT (UTC−7) and EDT (UTC−4). The two zones move together, so the gap stays a constant 3 hours year-round. The converter above uses real time-zone data, so it stays correct even on the changeover weekends in March and November — the brief windows where the gap genuinely isn't 3 hours.
Quick PST → EST reference
- 6:00 AM PST → 9:00 AM EST
- 9:00 AM PST → 12:00 PM EST (noon)
- 12:00 PM PST → 3:00 PM EST
- 3:00 PM PST → 6:00 PM EST
- 9:00 PM PST → 12:00 AM EST (next day)
What's a good meeting time across both coasts?
The overlap of normal working hours is roughly 9:00 AM–2:00 PM Pacific (12:00 PM–5:00 PM Eastern). Mornings on the East Coast are before the West Coast is online; late East Coast afternoons are West Coast lunch. Splitting the difference around 11:00 AM PST / 2:00 PM EST tends to work for everyone.
Is "PST" correct in summer?
Strictly, no — from mid-March to early November the West Coast is on PDT, not PST, and people just say "Pacific Time". Most of us write "PST" year-round out of habit. This tool follows the actual Pacific zone, so the result is right regardless of which abbreviation you used.
Need the reverse or other zones?
