New York and Seoul have no shared working hours, so a recurring live meeting always costs someone their morning or their evening. Rotating the burden, or moving the update to written form, is usually the better answer.
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.
