Best time for work calls
If you are scheduling a call between San José and San Francisco, the overlap window is limited to typical business hours. When it is 10 am in San José it is 9 am in San Francisco — a workable window for scheduling. The latest reasonable overlap is around 5 pm in San José (4 pm in San Francisco). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
San José and San Francisco have a comfortable window for a family call — no awkward alarms required. San José is 1 hour ahead of San Francisco, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in San José — that lands at 5 pm to 9 pm in San Francisco, 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.
