About the Buenos Aires-Chicago gap
Buenos Aires sits in the America/Argentina/Buenos_Aires time zone (UTC−3), while Chicago uses America/Chicago (CDT). That puts Chicago 2 hours behind of Buenos Aires right now.
These two cities do not handle daylight saving the same way, one adjusts its clocks seasonally and the other does not. The difference between them therefore moves by an hour twice a year, which is a common cause of missed meetings. The clocks above always show the live position rather than an assumed offset.
For scheduling, the practical overlap runs from 11:00 to 17:00 in Buenos Aires. Booking inside that band means neither party is dialling in before breakfast or after dinner.
