About time in Chicago

Chicago is the largest city in the Central Time Zone, sitting at UTC-6 in winter and shifting to UTC-5 for Central Daylight Time in the warmer half of the year. It runs one hour behind New York and two hours ahead of Los Angeles, making it a natural midpoint for coordinating calls across the country. The city's CME Group and Chicago Board of Trade keep commodity and futures markets humming on Central hours. For much of the Midwest, Chicago's clock is the reference everyone sets their day by.

Chicago changes its clocks for daylight saving time, so its exact UTC offset depends on the season (UTC-6 (UTC-5 in summer)). The live clock above reads Chicago's local time directly from the IANA time zone database in your browser, using the rules installed on your device.

Daylight in Chicago through 2026

Chicago sits at about 41.9°N, 87.6°W. The longest day of 2026 is June 19, with 15h 14m between sunrise and sunset. The shortest is December 17, with 9h 08m, a difference of 6 h 6 min. At this mid-latitude, winter evenings are dark early and summer evenings stay light well after a normal working day.

The earliest sunrise of the year comes around June 12 (05:14) and the latest sunset around June 21 (20:29). These are not exactly on the solstice because the sun’s position runs slightly ahead of or behind clock time during the year.

Solar noon, when the sun is highest, falls at about 12:57 local time in late March, 12:52 in late June and 11:48 in late December. In standard time the sun is highest at about 11:51 on average, close to 12:00, so the clock and the sun are well aligned in Chicago. During daylight saving time everything moves an hour later on the clock.
