Adelaide is 19.5 hours ahead of Anchorage
Best overlap: 12:30 PM to 6:30 PM in Anchorage is 8:00 AM to 2:00 PM in Adelaide.
For the smoothest call, aim inside 12:30 PM to 6:30 PM in Anchorage, i.e. 8:00 AM to 2:00 PM in Adelaide. This is one of the easier pairings: 6 hours of shared time means flexible, low-stress scheduling. Remember Adelaide is a day apart — the next day — so a late call for Anchorage could be the following morning there.
