Karachi is 3 hours ahead of Munich
Best overlap: 8:00 AM to 3:00 PM in Munich is 11:00 AM to 6:00 PM in Karachi.
Aim for 8:00 AM to 3:00 PM Munich time — that's 11:00 AM to 6:00 PM over in Karachi. Because you share 7 hours of the workday, there's no need to compromise; book the time that suits the meeting, not the map. Because Munich and Karachi don't both observe daylight saving, plan to re-check the overlap around March and November.
