America/Chicago · UTC−6
Chicago keeps Central Standard Time (CST, UTC−6) through the winter and moves to Central Daylight Time (CDT, UTC−5) from the second Sunday in March to the first Sunday in November. The clock above already has the correct one applied, so there is nothing to work out by hand. Chicago anchors the US Central zone: one hour behind New York, two ahead of Los Angeles.

Common questions
- What time is it in Chicago right now?
- The clock at the top of this page shows the current time in Chicago, updated every second, with today's date and the day of the week beneath it. It reads your device's clock and converts it using the America/Chicago rules, so it stays correct across daylight-saving changes.
- What is the UTC offset in Chicago?
- CST is UTC−6 and CDT is UTC−5. Chicago is on CDT from the second Sunday in March to the first Sunday in November, and on CST for the rest of the year.
- Does Chicago observe daylight saving time?
- Yes. Clocks go forward an hour for Central Daylight Time, which runs from the second Sunday in March to the first Sunday in November, and back again at the end of it.
- What is the IANA timezone for Chicago?
- America/Chicago. That is the identifier to use in code (a database column, a cron schedule, an Intl.DateTimeFormat call), because it carries the full history of offset and daylight-saving changes for Chicago rather than one fixed number.
