Time Difference: New York and San Francisco
San Francisco is 3 hours behind New York, all year. When it's 12:00 PM in New York, it's 9:00 AM in San Francisco.
Daylight saving note: New York and San Francisco change their clocks on the same US dates, the second Sunday in March and the first Sunday in November, so San Francisco is always 3 hours behind.
Coast to Coast: Always Three Hours
San Francisco follows Pacific Time, the same zone as Los Angeles and Seattle. New York follows Eastern Time. Both move their clocks on the same US dates, so the gap holds at three hours. Take 3 hours off a New York time to get San Francisco.
Think of it as a three-hour head start for the East Coast. 8:30 AM in New York is 5:30 AM in San Francisco, and New York's 5:00 PM close is 2:00 PM on the West Coast.
The West Coast morning is the East Coast's lunch hour. 9:00 AM in San Francisco is 12:00 PM in New York, and 4:00 PM there is 7:00 PM, after the New York day has ended.

Best Meeting Time for New York and San Francisco
The shared window runs from noon to 5:00 PM in New York, which is 9:00 AM to 2:00 PM in San Francisco, 5 hours. A 1:00 PM New York start (10:00 AM in San Francisco) is a safe default. Start before noon and the Bay Area is still before its 9:00 AM start.
Avoiding New York-San Francisco Time Mistakes
San Francisco is behind, so an early morning in New York is still the previous calendar day in San Francisco. With a 3 hours gap, that applies to anything before 3:00 AM in New York: 2:30 AM there is 11:30 PM the previous day in San Francisco.
Booking an Eastern morning slot is the mistake that happens most often. A 9:00 AM Eastern call lands at 6:00 AM in San Francisco. If you need someone in the Bay Area, wait for noon in New York, which is 9:00 AM there.
A Worked Example: A Product Meeting Across Two Coasts
Say a New York team and a San Francisco team meet weekly. If New York picks 2:00 PM, San Francisco joins at 11:00 AM. If San Francisco picks 10:00 AM, New York joins at 1:00 PM, still before the New York day ends.
The slots that fail are the early and late ones. New York's 8:00 AM is 5:00 AM in San Francisco, and San Francisco's 3:00 PM is 6:00 PM in New York. Both are outside a standard 9-to-5.
The gap holds through March and November, so a series set in either city stays correct.
For the invite, name the cities and show both times, such as "Product sync, 2:00 PM New York / 11:00 AM San Francisco". If a third location joins, add its time as a third entry. A standard format makes it easy to see at a glance which side the slot is anchored to, which helps whenever someone proposes moving the meeting.
