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 Central Daylight Time (CDT) to Coordinated Universal Time (UTC) for any date and time.
UTC is 5 hours ahead of Central Time from March to November, and 6 hours ahead the rest of the year.
Right now Central Time is on CST (UTC−6) and UTC is UTC+0. Central Time switches to daylight saving time on 14 March 2027.
9:00 am to 5:00 pm CST is 3:00 pm to 11:00 pm UTC.

Central Daylight Time is UTC−5. CDT is also used for Cuba Daylight Time (UTC−4). This page converts North American Central Time.
Texas, Illinois, Minnesota, Louisiana and most of the Midwest and South, plus Manitoba, from March to November. Saskatchewan and most of Mexico don't switch to CDT.
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.
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.
