Why people convert AEDT to KST time
- Scheduling a call from AEDT to KST: a 10:00 AM start in AEDT lands at 8:00 AM in KST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AEDT and KST are inside the 9-to-5 working day between 11:00 AM and 5:00 PM AEDT time (9:00 AM–3:00 PM KST). That is roughly 6 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in AEDT is 6:00 PM in KST makes it easy to avoid calling at 3 AM.
- 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 KST 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 KST (Korea Standard Time)
Korea Standard Time (KST) is the time zone used in South Korea. It shares the same UTC offset as Japan Standard Time but is a distinct time zone. South Korea does not observe daylight saving time. Seoul, the capital, is a major global tech and business hub.
Best time to call between AEDT and KST
Both AEDT and KST sit inside the 9 AM – 5 PM working day between 11:00 AM–5:00 PM AEDT, which is 9:00 AM–3:00 PM KST. That gives roughly 6 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
AEDT and KST share 6 hours of working-hours overlap (11:00 AM–5:00 PM AEDT), so scheduling a live meeting is straightforward.
AEDT is 2 hours behind KST (AEDT UTC+11:00 → KST UTC+09:00). The shared working window is 11:00 AM–5:00 PM AEDT. Remember to re-check around daylight-saving transitions.
