If you are scheduling a call between Tokyo and Mumbai, the overlap window is limited to typical business hours. When it is 12 pm in Tokyo it is 9 am in Mumbai β a workable window for scheduling. The latest reasonable overlap is around 5 pm in Tokyo (1 pm in Mumbai). Outside this window there is effectively no good overlap for regular office hours.
Tokyo and Mumbai have a comfortable window for a family call β no awkward alarms required. Tokyo is 3.5 hours ahead of Mumbai, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in Tokyo β that lands at 2:30 pm to 6:30 pm in Mumbai, 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.
