If you are scheduling a call between Kolkata and San José, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.
Kolkata and San José have a comfortable window for a family call — no awkward alarms required. Kolkata is 11.5 hours ahead of San José, which gives you 3 hours of genuine overlap when both sides are free. Aim for between 7:30 pm and 10 pm in Kolkata — that lands at 8 am to 10:30 am 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.
