Melbourne is 20 hours ahead of Honolulu
Best overlap: 12:00 PM to 6:00 PM in Honolulu is 8:00 AM to 2:00 PM in Melbourne.
Aim for 12:00 PM to 6:00 PM Honolulu time — that's 8:00 AM to 2:00 PM over in Melbourne. Melbourne is 20 hours ahead of Honolulu, but you still share a generous 6 hours of overlap, so scheduling is easy and there's room to move a meeting when you need to. Don't get caught out: Melbourne is the next day from Honolulu, so "tomorrow" means different things to each team. Keep an eye on the calendar — Melbourne observes daylight saving and Honolulu doesn't, which nudges this window by an hour twice a year.
