Converting Japan Standard Time to Australian Eastern Standard Time
Japan Standard Time (JST) and Australian Eastern Standard Time (AEST) are separated by a 1 hour time difference. AEST is 1 hour ahead of JST. JST is UTC+9, used in Japan, while AEST is UTC+10, used in Australia.
When converting from JST to AEST, the key reference points to remember are: 9:00 AM JST equals 10:00 AM AEST, 12:00 PM noon JST equals 1:00 PM AEST, and 5:00 PM JST equals 6:00 PM AEST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across JST and AEST
For professionals scheduling meetings between JST 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 1 hour difference, the window of overlap may be limited. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
JST does not observe Daylight Saving Time, maintaining UTC+9 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.
