FAQ
How many hours between Chicago and Singapore?
Singapore is 13 hours ahead of Chicago (+13 hours).
When is the best time for a meeting?
There is no time that suits both: Chicago works 09:00–17:00 and Singapore works 09:00–18:00 locally, and those never coincide. Someone has to take the call outside office hours.
