Public holidays to avoid
Dates where one side is off work while the other is not are the most common cause of no-shows on this route.
- Tuesday, November 3, 2026 — Melbourne Cup — Sydney is off, Seoul is working.
- Friday, December 25, 2026 — Christmas Day and Christmas Day; both cities are off.
- Monday, December 28, 2026 — St. Stephen's Day — Sydney is off, Seoul is working.
With 7 shared working hours, Seoul and Sydney can run standing meetings without anyone giving up an evening — as long as the slot sits inside that window on both sides of the next clock change.
Sending a booking link avoids the arithmetic entirely: each side picks a time in their own zone and both calendars get the correct local time, including after a daylight-saving change. See how LemCall handles cross-timezone bookings.
