Chicago’s time zone
Chicago keeps Central Time: CST (UTC−6) for the colder months and CDT (UTC−5) while daylight saving is on. Next, the clocks go back on Sunday 1 November 2026 and forward again on Sunday 14 March 2027. Phones and computers set Chicago’s clocks from the America/Chicago zone of the IANA tz database, and so does this page.
Chicago sets the time for the US Central zone, which stretches from the Gulf Coast of Texas to Manitoba’s border and includes Dallas, Houston, Minneapolis, New Orleans and Kansas City. The city joined Central Time with the railroads on 18 November 1883 and, like New York, ran its own daylight saving under city rules between the 1920s and 1966.
It briefly left the zone altogether. On 1 March 1936 Chicago moved to Eastern Standard Time, an hour ahead of its neighbours, and moved back on 15 November that year after the experiment proved unpopular. Since 2007 the city has followed the federal calendar: forward on the second Sunday in March, back on the first Sunday in November. Chicago is an hour behind New York all year, which makes it a natural midpoint for meetings that span both coasts; 11:00 am in Chicago is noon in New York and 9:00 am in Los Angeles.
CST = UTC −6 · CDT = UTC −5
