CET and CDT on the World Map
The map below highlights the CET (Central European Time) and CDT (Central Daylight Time) timezone regions across the globe.
CET – Central European Time
UTC+01:00Central European Time (CET) is used across most of Western and Central Europe, 1 hour ahead of UTC.
- •CET covers more European countries than any other time zone.
- •Spain uses CET despite being geographically aligned with GMT/WET.
- •The Frankfurt Stock Exchange, Euronext (Amsterdam/Paris), and Borsa Italiana operate on CET.
- •Over 500 million people live in the CET time zone.
- •France moved to CET during the German occupation in WWII and never switched back.
CDT – Central Daylight Time
UTC-05:00Central Daylight Time (CDT) is the daylight saving offset in the Central Time Zone, 5 hours behind UTC.
- •CDT is the same offset as EST (UTC-05:00), which can cause confusion.
- •CDT runs from the second Sunday in March to the first Sunday in November.
Everything You Need to Know About CET and CDT Time
CET runs on Central European Time (CET) at UTC+01:00. CDT runs on Central Daylight Time (CDT) at UTC-05:00. That puts CET 6 hours behind CDT — a difference of -6h at the current offsets.
In practice, when it is 9:00 AM in CET it is 3:00 AM in CDT. Midnight in CET is 6:00 PM in CDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CET to CDT time
- Scheduling a call from CET to CDT: a 10:00 AM start in CET lands at 4:00 AM in CDT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both CET and CDT are inside the 9-to-5 working day between 3:00 PM and 5:00 PM CET time (9:00 AM–11:00 AM CDT). That is roughly 2 hours of usable overlap.
- Watching a live event or market open: CET viewers need 3:00 AM in CDT to catch a 9:00 AM start there, and 6:00 AM if the event is anchored to CET.
- Always state the zone abbreviation, not just the hour. "3:00 PM CET" is unambiguous; "3 PM" across a -6h gap is not.
- Block 3:00 PM–5:00 PM CET as the recurring meeting window if you work primarily from CET and need CDT colleagues present.
About CET (Central European Time)
Central European Time (CET) is the standard time zone for most of Europe, covering over 30 countries from Spain to Poland, and from Norway to Italy. CET is 1 hour ahead of GMT and is used by the European Union's most populous nations. During summer, most CET countries switch to Central European Summer Time (CEST, UTC+02:00). Major European financial markets in Frankfurt, Paris, and Amsterdam operate on CET.
About CDT (Central Daylight Time)
Central Daylight Time (CDT) is observed during summer months in the US and Canadian portions of the Central Time Zone. Clocks are moved forward by one hour, aligning with Eastern Standard Time (EST). Most of Mexico and Central America do not observe CDT, staying on CST year-round.
Best time to call between CET and CDT
Both CET and CDT sit inside the 9 AM – 5 PM working day between 3:00 PM–5:00 PM CET, which is 9:00 AM–11:00 AM CDT. That gives roughly 2 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
CET and CDT overlap for about 2 hours during the working day — enough for meetings if you avoid the edges of the window.
CET is 6 hours behind CDT (CET UTC+01:00 → CDT UTC-05:00). The shared working window is 3:00 PM–5:00 PM CET. Remember to re-check around daylight-saving transitions.
