Chicago – London FAQ

What time is 9 AM CST in London?

9:00 AM CST is 3:00 PM GMT in winter. In summer, 9:00 AM CDT is 3:00 PM BST — the six-hour gap holds except during the short DST-changeover weeks.

What is the best Chicago–London meeting time?

Between 9:00 and 11:00 AM Chicago time (3:00–5:00 PM London). Later starts push UK attendees toward evening commutes.

Is Chicago easier than New York for UK calls?

No — Chicago is one hour farther west, so the standard overlap is about two hours (9:00–11:00 AM Chicago / 3:00–5:00 PM London) versus three for New York. The later sunrise can feel calmer, but it is a narrower window.
