Planning a call between Chicago and Singapore
No shared business hours. Chicago and Singapore have no overlap inside a working day, so someone has to take it outside theirs. The closest thing to common ground is 7 am to 9 am in Chicago (8:00 PM to 10:00 PM in Singapore), when both cities are at least awake.
Daylight saving
Chicago is on UTC−5 (CDT). Clocks go back one hour on Sunday, November 1, 2026, moving it to UTC−6. Between that date and the other city’s own change, the gap between them is an hour different from usual.
Singapore does not change its clocks. It stays on UTC+8 (SGT) all year, so the gap to the other city only moves when the other city shifts.
