The overlap is a starting point, not the answer
This table shows when working hours overlap, but it can't see whose calendar is already full. Buenos Aires and Chicago might share a clean afternoon window on paper and still have nobody free at the same moment.
The fix is a free Timespree availability poll. Share one link, everyone shades when they're actually free, and each person sees the grid in their own local time automatically. No sign-up, no time-zone math, no wrong-hour mistakes. The darkest slot is your meeting.
