Turn a Central European Time reading into Coordinated Universal Time. The panels show both clocks live, and the roller lets you line up any CET/CEST time against its UTC equivalent.
Central European Time
Coordinated Universal Time
US Eastern Time
THE CLOCKS ABOVE ALWAYS SHOW THE LIVE CURRENT TIME. THE ROLLER BELOW IS A LOOKUP TOOL — ROTATING IT NEVER CHANGES THEM.
CET/CEST is 2 hours ahead of UTC
ET is 4 hours behind UTC
France is 6 hours ahead of United States (Eastern)

Central European Time is the local clock in France. Converting it to UTC removes the local offset so the time can be shared with anyone in the world without ambiguity — which is exactly why UTC is used for servers, aviation and international scheduling.
France shares Central European Time with most of the EU, making cross-border meetings simple.
Subtract the current offset shown in the offset panel from the local CET/CEST time. If the result goes below 00:00, UTC is still on the previous date. Use the roller to read the pairing directly instead of doing the arithmetic.
Because CET/CEST observes daylight saving time, the gap to UTC is not fixed — every clock and table on this page is calculated live from the Europe/Paris IANA database, so today's real offset is always what you see.
Early-morning or late-night local times frequently sit on a different UTC date. The converter labels every selection as SAME DAY, NEXT DAY or PREVIOUS DAY so a deadline written in UTC is never off by 24 hours.
France switches between CET (UTC +01:00) and CEST (UTC +02:00) on the EU schedule, late March to late October.
