About This Time Zone Pair

US–Europe calls usually fit best in the US morning and European afternoon. Use the overlap table for the exact cities and date.

During those windows, the offset between London and Chicago changes by one hour. A city-anchored calendar invite keeps the anchor city fixed while the other city's local time changes.
