HST to AWST: convert Hawaii Standard Time to Australian Western Standard Time

AWST is 18 hours ahead of HST all year.

Neither clock changes for daylight saving, so the gap never moves.

Scheduling a call between HST and AWST

Standard business hours (9:00 AM to 5:00 PM) do not overlap: daytime in Hawaii Standard Time falls outside the working day in Australian Western Standard Time, so one side needs an early morning or late evening.
