No working-hours overlap
Chicago and Sydney sit far enough apart that neither city's 9am–6pm window touches the other's. One side takes the call outside working hours, or the conversation moves async.
Time-zone gaps are the single biggest reason distributed meetings get rescheduled. The numbers above are today's live UTC offsets for Chicago and Sydney; the pair drifts by an hour when one side enters or exits daylight saving and the other doesn't.
When you send a booking link from a tool that resolves IANA timezone IDs — instead of a static "EST" or "GMT" label — every attendee gets the correct local time for the day of the call, not the day the link was sent. That eliminates the "wait, is that Chicago time or mine?" reply thread. See how LemCal handles cross-timezone bookings.
