Colombo 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 Colombo.
Book within 8:30 AM to 1:30 PM Hamburg time (1:00 PM to 6:00 PM in Colombo) and both teams will be at work. With 5 hours to play with, a mid-window meeting keeps things balanced for Hamburg and Colombo alike. Don't be caught out by clock changes — Hamburg observes daylight saving and Colombo doesn't, so the offset varies by an hour through the year.
