Open Meeting Planner →Los Angeles is a entertainment city and Seoul a electronics city; the two economies buy from each other rather than compete. Put simply, when it is 09:00 in Los Angeles it is already 16 hours later in Seoul, on the following date.
Both cities work Monday to Friday, Los Angeles typically 09:00–18:00 and Seoul 09:00–18:00 local time.
There is no hour when both offices are open, only the edges: an early start in Los Angeles meets a late finish in Seoul. Alternate who stretches, and keep those calls short. Only Los Angeles changes its clocks, so the gap shifts by an hour twice a year while Seoul stays put.
Seoul is 16 hours ahead of Los Angeles. The gap changes by an hour around the clock changes.
There is no hour when both offices are open. The closest is early morning in Los Angeles against the end of the day in Seoul; alternate which side takes the awkward slot.
Alternate. A standing call that is always 07:00 for Los Angeles or always 19:00 for Seoul is resented within a month; rotating it keeps both sides in the room.
Not always. At 09:00 in Los Angeles it is already the next calendar day in Seoul, so every invitation should carry the date in both cities.
