Best Meeting Time: Sydney to Seoul
🕐 Live Timezone Overlap: Sydney & Seoul
Sydney and Seoul sit just one hour apart, which makes this one of the more comfortable same-day pairings in the Asia-Pacific region. Both cities share a standard 9am-6pm working day, producing a generous 8-hour overlap. The main scheduling consideration is Sydney's daylight saving time: when Sydney shifts to AEDT, the gap closes to zero, meaning Seoul and Sydney are briefly on the same UTC offset, and any standing meetings need no time adjustment at all.
Time Difference: Sydney and Seoul
Seoul is currently 1 hour behind Sydney. The live offsets are Sydney UTC+10 and Seoul UTC+9. Sydney observes daylight saving and Seoul does not, so the offset shifts twice a year if both sides aren't already aligned.
Seoul runs UTC+9 year-round. South Korea does not observe DST. Sydney normally runs AEST at UTC+10, putting Seoul one hour behind. However, Sydney observes daylight saving from the first Sunday in October to the first Sunday in April, pushing Sydney to UTC+11. During that period the gap widens to two hours. Outside those months, the difference is just one hour, making Sydney-to-Seoul scheduling unusually straightforward for a trans-national pair.
Best Times to Meet
The 8-hour overlap runs 10am-6pm in Sydney and 9am-5pm in Seoul. Inside that 8-hour window, the cleanest slot is typically 10am-12pm Sydney time (9am-11am Seoul), catching Seoul colleagues early while Sydney is freshly into the working day. Avoid late Friday afternoon in Seoul: business meetings then are uncommon, as Friday evenings carry a strong social tradition in many Seoul firms. Sydney's summer holiday season, from mid-November through to Australia Day on 26 January, means skeleton staffing, so confirm availability on both sides.

Tips for Scheduling Across Sydney and Seoul
- Book recurring Sydney-Seoul calls for 10am-11am Sydney time to catch Seoul at a fresh 9am start.
- When Sydney enters AEDT in October, the gap widens to two hours: update calendar invites immediately to avoid Seoul missing calls.
- Avoid scheduling Seoul meetings on Friday afternoons; business discussions late Friday are uncommon in many Seoul workplaces.
- Check Seollal and Chuseok dates each year: both bring three-to-four-day Seoul closures that shift annually with the lunar calendar.
- Sydney offices run on skeleton staff between Christmas and Australia Day (26 January); plan Seoul-side deadlines around this gap.
Public Holidays and Working Weeks
Both cities follow a Monday-to-Friday working week with 9am-6pm hours as the common pattern. Seoul's working hours have been legally capped at 52 per week since 2018, though many firms extend beyond 6pm in practice. Key dates to watch: Seoul observes Seollal and Chuseok, each bringing three-to-four-day national closures. Sydney observes Australia Day (26 January) and ANZAC Day (25 April). Cross-city meetings should account for both calendars, particularly around the movable Korean lunar holidays.
