See the live UTC time next to the current time in Chicago, check today's real offset, and roll through any UTC time to find the matching CT time — including when the two zones fall on different dates.

Coordinated Universal Time (UTC) is the world's time standard: it never shifts for seasons and every other zone is described as an offset from it. US Central Time (CT) is the clock used in Chicago. Converting UTC to CT means adding that offset to the UTC reading.
Central Time covers the US Midwest and Gulf states, from Chicago to Dallas and New Orleans.
Take the UTC time, apply the current CT offset shown in the live panel above, and roll the date forward or back if the result crosses midnight. The interactive roller does all three steps for you: the left drum is UTC, the right drum is CT, and a day badge appears whenever the local date differs.
Because CT observes daylight saving time, the gap to UTC is not fixed — every clock and table on this page is calculated live from the America/Chicago IANA database, so today's real offset is always what you see.
The reference table below the tool lists every UTC half hour against the matching CT time for today, so you can copy a conversion without touching the roller.
Central Time is UTC -06:00 as CST in winter and UTC -05:00 as CDT from March to November.
