Why people convert Chicago to SAST time

- Finding shared working hours: both Chicago and SAST are inside the 9-to-5 working day between 9:00 AM and 10:00 AM CDT time (4:00 PM–5:00 PM SAST). That is roughly 1 hours of usable overlap.
- Watching a live event or market open: Chicago viewers need 4:00 PM in SAST to catch a 9:00 AM start there, and 5:00 PM if the event is anchored to Chicago.
- Always state the zone abbreviation, not just the hour. "3:00 PM CDT" is unambiguous; "3 PM" across a +7h gap is not.
