What is CET in CST?
Central Time is 7 hours behind
Central European Time is on UTC+2:00 and Central Time is on UTC−5:00 right now. Both are on daylight saving, so their clocks read CEST and CDT. The gap changes during the year — see below.

When the difference changes
Central European Time and Central Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – October 25, 2026Central Time is 7 hours behind
- October 25, 2026 – November 1, 2026Central Time is 6 hours behind
- November 1, 2026 – March 14, 2027Central Time is 7 hours behind
- March 14, 2027 – March 28, 2027Central Time is 6 hours behind
- March 28, 2027 – onwardsCentral Time is 7 hours behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.

Scheduling between the two
Working hours overlap from 4:00 pm to 6:00 pm CEST, which is 9:00 am to 11:00 am CDT. Anything inside that window falls in the normal working day at both ends.
A note on CST: it can also mean China Standard Time (UTC+8) and Cuba Standard Time (UTC−5). This page means US Central Time.
