How does daylight saving affect CET to CEST?
The labels CET and CEST are fixed offsets, so the result on this page is always exact. Both regions move their clocks for daylight saving on roughly the same weekends, so the 1 hour gap usually holds steady right through the year.
Why can you trust this CET to CEST converter?
Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so CET to CEST stays accurate for today and for any past or future date you type in.
