There is no standard 8-to-6 overlap. Someone joins early or late.
For Singapore and Chicago, the standard workday in one city falls outside office hours in the other — that's what 13 hours of distance does. Keep live syncs short and infrequent, and let written updates carry the day-to-day between Singapore and Chicago. Because only Chicago changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Chicago enters or leaves daylight saving.
