Why people convert AEDT to Japan time
- Scheduling a call from AEDT to Japan: a 10:00 AM start in AEDT lands at 8:00 AM in Japan, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AEDT and Japan are inside the 9-to-5 working day between 11:00 AM and 5:00 PM AEDT time (9:00 AM–3:00 PM JST). That is roughly 6 hours of usable overlap.
- Booking travel or deliveries: tracking Japan local time against AEDT keeps pickup windows and arrival estimates honest across the -2h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEDT" is unambiguous; "3 PM" across a -2h gap is not.
- Block 11:00 AM–5:00 PM AEDT as the recurring meeting window if you work primarily from AEDT and need Japan colleagues present.
About AEDT (Australian Eastern Daylight Time)
Australian Eastern Daylight Time (AEDT) is the daylight saving period in south-eastern Australia, one hour ahead of Australian Eastern Standard Time (AEST, UTC+10:00). Because Australia is in the southern hemisphere, AEDT runs through the summer — from the first Sunday in October to the first Sunday in April — which is almost exactly the reverse of the European and North American schedules. New South Wales, Victoria, Tasmania and the Australian Capital Territory observe it; Queensland and the Northern Territory do not, so Brisbane stays on AEST year round while Sydney moves to AEDT. During AEDT, Sydney is 11 hours ahead of UTC and 16 hours ahead of New York.
About JST (Japan Standard Time)
Japan Standard Time (JST) is the standard time zone for all of Japan. Japan does not observe daylight saving time. JST is 9 hours ahead of UTC and 14 hours ahead of EST. The Tokyo Stock Exchange, the world's third largest by market capitalization, operates on JST. South Korea uses the same offset (KST) but it is a distinct time zone.
