CET to CST Time Zone Converter
CET is Central European Time — Paris, Berlin, Madrid, and Rome (CET in winter, CEST in summer). CST is US Central Time, the clock in Chicago, Dallas, and Houston. Central runs about seven hours behind Central Europe for most of the year, and this converter applies the right offset for any date, daylight saving included.

Daylight saving is applied automatically for the date you pick. Labels like PST/EST name the zone (Pacific/Eastern); the real abbreviation shifts to PDT/EDT during daylight saving, and gmt here means London (GMT in winter, BST in summer) while utc stays fixed.
The time difference
US Central Time is 7 hours behind Central Europe for most of the year, in both winter and summer, because the anchor dates land in aligned periods. The one catch: during March 8–29 and October 25–November 1, 2026, the US and Europe haven't both switched yet, so the gap is briefly off by one hour.
A worked example
Take 9:00 AM in Central Europe. On January 15, 2026 that is 2:00 AM in Chicago the same day. On July 15, 2026 it's again 2:00 AM in Chicago — the seven-hour gap holds across seasons, so one value covers most of the year. That's the small hours stateside: a mid-morning European meeting is the middle of the night in Texas.
Daylight saving & the abbreviation caveat
The slug says "CST," but Central shifts to CDT from spring to fall — locals just say CT. Both Europe and the US observe daylight saving, but on different dates, which is why the usual seven-hour gap slides by an hour during those late-March and late-October windows. The converter uses the exact date you choose, so the result is never off.
When you'll use it
Handy for scheduling calls with a Chicago or Dallas team, timing US Central market and event start times from Europe, planning flights, and coordinating remote work across a seven-hour spread.
Frequently asked questions
How many hours behind CET is US Central Time?
Usually seven hours. When it's 4:00 PM in Rome it's 9:00 AM in Chicago. For a couple of weeks in spring and fall the gap is briefly six hours.
Why does the gap wobble by an hour twice a year?
The US switches clocks on March 8 and November 1, 2026, while Europe switches on March 29 and October 25. In the gaps between those dates only one side has moved, so the difference shifts by an hour.
Is CST the same as CT?
CT is the everyday name locals use. CST is Central's winter label and CDT its summer one; the converter picks the right one for your date automatically.
