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