Time Zone & Business Hours — Chicago
Chicago operates on Central Time, one hour behind New York, and hosts the CME Group — the world's largest derivatives exchange. Central Standard Time (CST, UTC−6) and Central Daylight Time (CDT, UTC−5) govern the daily rhythm of futures and commodities trading across North America.
Central Time in Chicago shifts once in spring and once in autumn: clocks move forward in March to CDT (UTC−5) and back in November to CST (UTC−6). The CME Group's trading sessions are timed to these transitions.
