If you are scheduling a call between Kolkata and Bangkok, the overlap window is limited to typical business hours. When it is 9 am in Kolkata it is 10 am in Bangkok — a workable window for scheduling. The latest reasonable overlap is around 3 pm in Kolkata (5 pm in Bangkok). Outside this window there is effectively no good overlap for regular office hours.
Kolkata and Bangkok have a comfortable window for a family call — no awkward alarms required. Kolkata is 1.5 hours behind Bangkok, which gives you 2 hours of genuine overlap when both sides are free. Aim for between 6 pm and 7:30 pm in Kolkata — that lands at 7:30 pm to 9 pm in Bangkok, 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.
