Best time for work calls
If you are scheduling a call between San Francisco and San José, the overlap window is limited to typical business hours. When it is 9 am in San Francisco it is 10 am in San José — a workable window for scheduling. The latest reasonable overlap is around 4 pm in San Francisco (5 pm in San José). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
San Francisco and San José have a comfortable window for a family call — no awkward alarms required. San Francisco is 1 hour behind San José, which gives you 2 hours of genuine overlap when both sides are free. Aim for between 6 pm and 8 pm in San Francisco — that lands at 7 pm to 9 pm in San José, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
