Central Time trails London by 5 hours most of the year, occasionally narrowing to 4 for a short stretch when the US and UK haven't yet both flipped their clocks for the season.

As one of the country's major commodities-trading and financial centers, Chicago has a steady, recurring reason to check this specific conversion around exact market-open and market-close moments rather than a remembered rule of thumb.

The default slot most Midwest-UK teams settle into is a Chicago mid-morning call, roughly 9-10am Central, landing early afternoon in London — comfortably inside a normal workday on both ends.

Chicago-London FAQ

How many hours behind is Chicago compared to London?

Usually 6 hours, or 5 hours during the brief weeks when the US and UK's Daylight Saving Time transitions haven't yet aligned for the year.

What's a good default meeting time?

A Chicago mid-morning start keeps the call inside London's afternoon office hours rather than catching that side right at close of business.
