Best overlap: 8:00 AM to 11:00 AM in Hamburg is 3:00 PM to 6:00 PM in Perth.
Aim for 8:00 AM to 11:00 AM Hamburg time — that's 3:00 PM to 6:00 PM over in Perth. Perth is 7 hours ahead of Hamburg, leaving about 3 hours of daily overlap — enough for most meetings if you don't leave them too late in the day. Because Hamburg and Perth don't both observe daylight saving, plan to re-check the overlap around March and November.

The US to Australia gap runs 14 to 19 hours depending on the month, and someone is always in tomorrow. Exact overlap windows for every US coast, the double-DST trap, and a rotation rule that keeps it fair. -
