Chicago and London Time Zone Comparison
This page is built for anyone planning a call or meeting between Chicago and London. Chicago is the largest city in the U. London, the capital of the United Kingdom, is one of the world's leading financial centers, and much of global banking and stock-market activity is scheduled around London time.
Chicago is always 6 hours behind London, with no seasonal change, since neither city's daylight saving rules shift this relationship.
