How many hours between CET and ET?

CET is UTC+1 and ET is UTC-5/4, a difference of 6 hours. ET is behind CET. This difference can shift by an hour in either direction during Daylight Saving Time transitions — if one zone observes DST and the other doesn't, the offset narrows or widens for part of the year.

Business Hours Overlap: CET ↔ ET

Assuming a 9:00 AM – 5:00 PM workday on each side, your working-hours overlap window is 3:00 pm–5:00 pm cet (9:00 am–11:00 am et). To visualize this instantly for any pair of cities, use the visual meeting planner or the timezone overlap finder — both highlight the green overlap window on a live timeline.

Does CET observe Daylight Saving Time?

Central European Time (CET) is based on the Europe/Paris IANA timezone. DST observance depends on the jurisdiction — for example, most of the continental US switches between standard and daylight time, while India, Japan, and most of Southeast Asia do not observe DST at all. WorldClock.lol uses the authoritative IANA timezone database, so every conversion automatically accounts for the correct DST rules on the date you're converting.
