UTC: Coordinated Universal Time
Coordinated Universal Time is UTC+0.
The world's reference time. Every other zone is defined as an offset from UTC, and it never changes for daylight saving time. Servers, aviation and international deadlines use it.

UTC never changes for daylight saving time, but Central Time does, so the gap moves by an hour twice a year. The table below always shows the right one for your date.
Convert Coordinated Universal Time (UTC) to Central Daylight Time (CDT) for any date and time.
Central Time is 5 hours behind UTC from March to November, and 6 hours behind the rest of the year.
Right now UTC is UTC+0 and Central Time is on CST (UTC−6). Central Time switches to daylight saving time on 14 March 2027.

CDT isn't in use at the moment: Central Time is on CST (UTC−6) until 14 March 2027. The times on this page follow the clocks, so they show CST.
How the difference changes
Right now CST is 6 hours behind UTC. From 14 March 2027, when US clocks go forward, the difference becomes 5 hours. From 7 November 2027, when US clocks go back, the difference becomes 6 hours.
