Johannesburg is 8 hours ahead of Chicago right now.
Does the gap change?
The gap isn't fixed. Chicago changes its clocks for daylight saving time and Johannesburg doesn't, so the difference moves during the year:

- From around November 8, 2027: Johannesburg ahead by 8 hours
Best time to meet
Normal office hours in Johannesburg and Chicago don't overlap. The most workable window is 7 AM to 2 PM in Chicago, which is 3 PM to 10 PM in Johannesburg, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
