When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Chicago and Guangzhou don't overlap on the same weekday. Guangzhou is 13 hours ahead of Chicago.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Chicago (7 AM–9 AM the next day in Guangzhou) — suggest 7:00 PM Chicago (8:00 AM Guangzhou).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
This window may shift by an hour during daylight saving time.
Public holidays in 2026
National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
