CDT and CET on the World Map
The map below highlights the CDT (Central Daylight Time) and CET (Central European Time) timezone regions across the globe.
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.
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.
Everything You Need to Know About CDT and CET Time
CDT runs on Central Daylight Time (CDT) at UTC-05:00. CET runs on Central European Time (CET) at UTC+01:00. That puts CDT 6 hours ahead of CET — a difference of +6h at the current offsets.
In practice, when it is 9:00 AM in CDT it is 3:00 PM in CET. Midnight in CDT is 6:00 AM in CET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CDT to CET time
- Scheduling a call from CDT to CET: a 10:00 AM start in CDT lands at 4:00 PM in CET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both CDT and CET are inside the 9-to-5 working day between 9:00 AM and 11:00 AM CDT time (3:00 PM–5:00 PM CET). That is roughly 2 hours of usable overlap.
- Booking travel or deliveries: tracking CET local time against CDT keeps pickup windows and arrival estimates honest across the +6h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM CDT" is unambiguous; "3 PM" across a +6h gap is not.
- Block 9:00 AM–11:00 AM CDT as the recurring meeting window if you work primarily from CDT and need CET colleagues present.
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.
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.
Best time to call between CDT and CET
Both CDT and CET sit inside the 9 AM – 5 PM working day between 9:00 AM–11:00 AM CDT, which is 3:00 PM–5:00 PM CET. That gives roughly 2 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
CDT and CET overlap for about 2 hours during the working day — enough for meetings if you avoid the edges of the window.
CDT is 6 hours ahead of CET (CDT UTC-05:00 → CET UTC+01:00). The shared working window is 9:00 AM–11:00 AM CDT. Remember to re-check around daylight-saving transitions.
