Quick conversion examples
These examples use CDT (UTC-5) and CEST (UTC+2); choosing a date applies the local clock changes.
Conversion formula: CEST = CDT + 7h · CET = CST + 7h · CET = CDT + 6h.
| CDT | CEST |
|---|---|
| 6:00 AM CDT | = 1:00 PM CEST |
| 7:00 AM CDT | = 2:00 PM CEST |
| 8:00 AM CDT | = 3:00 PM CEST |
| 9:00 AM CDT | = 4:00 PM CEST |
| 10:00 AM CDT | = 5:00 PM CEST |
| 12:00 PM CDT | = 7:00 PM CEST |
| 3:00 PM CDT | = 10:00 PM CEST |
| 5:00 PM CDT | = 12:00 AM CEST (+1 day) |
| 6:00 PM CDT | = 1:00 AM CEST (+1 day) |
| 8:00 PM CDT | = 3:00 AM CEST (+1 day) |
