New York is always 3 hours ahead of San Francisco. When it's 3:00 PM in New York, it's 12:00 PM in San Francisco. Both cities observe daylight saving time on the same dates, so the 3-hour difference is constant year-round.
This consistent time difference makes scheduling between Wall Street and Silicon Valley straightforward for tech companies and financial firms.
Optimal meeting window: 12:00 PM - 5:00 PM New York time (9:00 AM - 2:00 PM San Francisco). This overlaps standard business hours in both cities.
Tech companies typically schedule all-hands meetings during this overlap to include both coasts.
