Best overlap: 12:30 PM to 6:30 PM in Kolkata is 8:00 AM to 2:00 PM in Dublin.
Book within 12:30 PM to 6:30 PM Kolkata time (8:00 AM to 2:00 PM in Dublin) and both teams will be at work. Dublin is 4.5 hours behind Kolkata, but with 6 hours of common ground you can hold morning or afternoon meetings without anyone working odd hours. For part of the year the maths changes: Dublin observes daylight saving, Kolkata does not, shifting the overlap by an hour.
