Converting Hawaii Standard Time to Australian Eastern Standard Time
Hawaii Standard Time (HST) and Australian Eastern Standard Time (AEST) are separated by a 20 hours time difference. AEST is 20 hours ahead of HST. HST is UTC-10, used in United States, while AEST is UTC+10, used in Australia.
When converting from HST to AEST, the key reference points to remember are: 9:00 AM HST equals 5:00 AM AEST, 12:00 PM noon HST equals 8:00 AM AEST, and 5:00 PM HST equals 1:00 PM AEST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across HST and AEST
For professionals scheduling meetings between HST and AEST, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 20 hours difference, the window of overlap may be limited, making early morning or late evening calls necessary for one party. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
HST does not observe Daylight Saving Time, maintaining UTC-10 year-round. AEST observes DST, switching to AEDT (UTC+11). During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
