Chennai is 4.5 hours ahead of Hamburg
Best overlap: 8:30 AM to 1:30 PM in Hamburg is 1:00 PM to 6:00 PM in Chennai.
Both teams are at their desks between 8:30 AM to 1:30 PM in Hamburg and 1:00 PM to 6:00 PM in Chennai. Roughly 5 hours of shared hours means scheduling takes a little care — 8:30 AM in Hamburg / 1:00 PM in Chennai is a safe default. A quick caveat — Hamburg's clocks move for daylight saving and Chennai's don't, so the times here are right for only part of the year.
