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