Working across Seoul and Zürich means respecting a 7h difference. Your 9 AM in Seoul is 2:00 AM in Zürich, and Zürich's 5 PM is 12:00 AM in Seoul. Neither number is intuitive until you've been burned by it on a live call.
1h of shared working time sounds like plenty until you factor in lunch breaks, context-switching, and the inevitable late start. In practice you have closer to 30 usable minutes for synchronous collaboration. Pick one meeting slot and protect it fiercely — let async workflows cover everything else.
The less obvious scheduling risk is daylight saving time mismatch. Seoul and Zürich may not shift their clocks on the same date. A meeting booked as "10 AM SEL" in January might show up as "11 AM SEL" in a colleague's calendar in March if your calendar app doesn't handle DST transitions correctly. Check the DST note on this page before setting up recurring meetings.
The bigger risk isn't the 7h gap — it's that the 1h overlap creates a false sense of availability. Both sides are reachable at the same time, so meetings proliferate. The most effective Seoul–Zürich teams treat their overlap window as a protected resource: one synchronized meeting per day maximum, async-first for everything else.
Seoul is UTC+9 and Zürich is UTC+2, a difference of 7h. This gap may shift by 1 hour during DST transitions.
The best meeting time is during the 1h of shared business hours — typically 4:00 PM to 5:00 PM GMT+9.
Yes, partially. Zürich observes daylight saving time; Seoul does not. Zürich's clocks change around March 29 and October 25, shifting the gap between the two cities by 1 hour for part of the year.
Seoul and Zürich share 1h of business-hours overlap (assuming 9 AM–5 PM local time for both).
