Best overlap: 8:00 AM to 3:00 PM in Paris is 11:30 AM to 6:30 PM in Kolkata.
Both offices are open during 8:00 AM to 3:00 PM Paris time, which is 11:30 AM to 6:30 PM in Kolkata. Kolkata is 3.5 hours ahead of Paris, and with 7 hours of overlap you can even run back-to-back calls without stepping outside business hours. Heads up: because Paris changes its clocks and Kolkata doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
