Best overlap: 12:30 PM to 6:30 PM in Kolkata is 8:00 AM to 2:00 PM in London.
Plan around 12:30 PM to 6:30 PM in Kolkata, which is 8:00 AM to 2:00 PM in London, to catch everyone during office hours. The overlap is wide at 6 hours, so you can protect mornings for deep work and still find plenty of meeting time. Seasonal note: London uses daylight saving and Kolkata doesn't, so double-check the times in your own months — they can move by an hour.
