Best overlap: 3:00 PM to 6:00 PM in San Diego is 8:00 AM to 11:00 AM in Brisbane.
Book within 3:00 PM to 6:00 PM San Diego time (8:00 AM to 11:00 AM in Brisbane) and both teams will be at work. Since Brisbane is 17 hours ahead of San Diego, the workdays overlap by around 3 hours; 3:00 PM in San Diego (8:00 AM in Brisbane) makes a reliable recurring slot. Remember Brisbane is a day apart — the next day — so a late call for San Diego could be the following morning there. For part of the year the maths changes: San Diego observes daylight saving, Brisbane does not, shifting the overlap by an hour.
