Best overlap: 8:00 AM to 9:00 AM in San Diego is 5:00 PM to 6:00 PM in Berlin.
For the smoothest call, aim inside 8:00 AM to 9:00 AM in San Diego, i.e. 5:00 PM to 6:00 PM in Berlin. Berlin is 9 hours ahead of San Diego, so common hours are scarce (about 1 hour). Lock the slot, keep it short, and follow up in writing.
