Colombo is 10.5 hours ahead of Chicago

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

The 10.5-hour difference means Chicago and Colombo miss each other entirely during regular office hours. Where you can, lean on async updates and save live calls for when one team is happy to start early or stay late. Seasonal note: Chicago uses daylight saving and Colombo doesn't, so double-check the times in your own months — they can move by an hour.
