Planning a call between Tokyo and Chicago
No shared business hours. Tokyo and Chicago 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 12 pm in Tokyo (5:00 PM to 10:00 PM in Chicago), when both cities are at least awake.
Daylight saving
Tokyo does not change its clocks. It stays on UTC+9 (JST) all year, so the gap to the other city only moves when the other city shifts.
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.
