Open Meeting Planner →Chicago's finance and derivatives and logistics and Johannesburg's mining and banking are different worlds, which is exactly why they call each other. Johannesburg runs 7 hours ahead of Chicago, far enough that the morning in one is already the next day in the other.
Both cities work Monday to Friday, Chicago typically 08:30–17:30 and Johannesburg 08:00–17:00 local time. On the Chicago side the dates that break a schedule are Thanksgiving (fourth Thursday of November, with the Friday) and Independence Day (4 July); on the Johannesburg side, Heritage Day (24 September) and Freedom Day (27 April).
The shared window is short: 09:00–10:00 Chicago time, 16:00–17:00 in Johannesburg. Guard it for the conversations that need everyone, and let the rest happen in writing. Only Chicago changes its clocks, so the gap shifts by an hour twice a year while Johannesburg stays put.
Johannesburg is 7 hours ahead of Chicago. The gap changes by an hour around the clock changes.
09:00–10:00 Chicago time, which is 16:00–17:00 in Johannesburg — the 1-hour stretch when both are inside 09:00–17:00.
Both work Monday to Friday, so any weekday works — but check the date, since the day of the week can differ between the two cities at the same instant.
Not always. At 09:00 in Chicago it is already the next calendar day in Johannesburg, so every invitation should carry the date in both cities.
