Chicago is 10.5 hours behind Colombo

There is no standard 8-to-6 overlap. Someone joins early or late.

Because Chicago is 10.5 hours behind Colombo, the two offices are essentially never open at the same time. If a live call is essential, aim for the very start or very end of a workday in one city and accept it'll be off-hours for the other. Note that Chicago follows daylight saving while Colombo stays put, so the times above drift by an hour seasonally.
