Every hour in Chicago and the corresponding time in Sydney. Green rows indicate business hours in Sydney.
Time zones
Chicago uses America/Chicago (CDT) and Sydney uses Australia/Sydney (GMT+10). The difference can shift during daylight saving changes, so checking the exact date matters.

Plan a meetingMeeting guidance
There is no full business-hour overlap in the 24-hour table, so use a custom time or rotate meeting times for fairness. For important calls, check the meeting date because the offset can change when either location enters or leaves daylight saving time.
