Best overlap: 8:00 AM to 3:00 PM in Berlin is 11:30 AM to 6:30 PM in Mumbai.
For the smoothest call, aim inside 8:00 AM to 3:00 PM in Berlin, i.e. 11:30 AM to 6:30 PM in Mumbai. Mumbai is 3.5 hours ahead of Berlin, but you'd hardly notice — 7 hours of shared hours makes this feel like working in neighbouring time zones. Daylight saving complicates things slightly: Berlin observes it, Mumbai doesn't, so the difference flexes by an hour part of the year.
