Converting Australian Eastern Standard Time to Hawaii Standard Time
Australian Eastern Standard Time (AEST) and Hawaii Standard Time (HST) are separated by a 20 hours time difference. HST is 20 hours behind AEST. AEST is UTC+10, used in Australia, while HST is UTC-10, used in United States.
When converting from AEST to HST, the key reference points to remember are: 9:00 AM AEST equals 1:00 PM HST, 12:00 PM noon AEST equals 4:00 PM HST, and 5:00 PM AEST equals 9:00 PM HST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across AEST and HST
For professionals scheduling meetings between AEST and HST, 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
AEST observes Daylight Saving Time, switching to AEDT (UTC+11) during summer months. HST does not observe DST, staying at UTC-10 year-round. 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.
