Best overlap: 8:00 AM to 3:00 PM in Prague is 11:30 AM to 6:30 PM in Kolkata.
Schedule calls for 8:00 AM to 3:00 PM in Prague — your colleagues in Kolkata will be online from 11:30 AM to 6:30 PM. Because you share 7 hours of the workday, there's no need to compromise; book the time that suits the meeting, not the map. Because Prague and Kolkata don't both observe daylight saving, plan to re-check the overlap around March and November.
