Turn a US Central Time reading into Coordinated Universal Time. The panels show both clocks live, and the roller lets you line up any CT time against its UTC equivalent.
US Central Time
Coordinated Universal Time
US Eastern Time
THE CLOCKS ABOVE ALWAYS SHOW THE LIVE CURRENT TIME. THE ROLLER BELOW IS A LOOKUP TOOL — ROTATING IT NEVER CHANGES THEM.
CT is 5 hours behind UTC
ET is 4 hours behind UTC
United States (Central) is 1 hour behind United States (Eastern)

US Central Time is the local clock in Chicago. Converting it to UTC removes the local offset so the time can be shared with anyone in the world without ambiguity — which is exactly why UTC is used for servers, aviation and international scheduling.
Central Time covers the US Midwest and Gulf states, from Chicago to Dallas and New Orleans.
Subtract the current offset shown in the offset panel from the local CT time. If the result goes below 00:00, UTC is still on the previous date. Use the roller to read the pairing directly instead of doing the arithmetic.
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.
Early-morning or late-night local times frequently sit on a different UTC date. The converter labels every selection as SAME DAY, NEXT DAY or PREVIOUS DAY so a deadline written in UTC is never off by 24 hours.
Central Time is UTC -06:00 as CST in winter and UTC -05:00 as CDT from March to November.
