If you are scheduling a call between San José and Chicago, the overlap window is limited to typical business hours. When it is 9 am in San José it is 10 am in Chicago — a workable window for scheduling. The latest reasonable overlap is around 4 pm in San José (5 pm in Chicago). Outside this window there is effectively no good overlap for regular office hours.
San José and Chicago have a comfortable window for a family call — no awkward alarms required. San José is 1 hour behind Chicago, which gives you 2 hours of genuine overlap when both sides are free. Aim for between 6 pm and 8 pm in San José — that lands at 7 pm to 9 pm in Chicago, 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.
