With 8 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.
