No locations currently on CDT. Would you like to see CST?
North America: CDT is currently not observed because locations are on standard time and are observing CST.
What Is Central Daylight Time?
It covers all or parts of 20 states in the US and three provinces or territories in Canada.
CDT or CST?
Central Daylight Time (CDT) is a North American time zone in use from the second Sunday in March to the first Sunday in November during Daylight Saving Time (DST). Central Standard Time (CST) is used during the remainder of the year.
CDT Is the Central Time Zone
In everyday usage, CDT is often referred to as Central Time (CT) or the Central Time Zone. This can add a bit of confusion as the term Central Time does not differentiate between standard time and Daylight Saving Time, so Central Time switches between CST and CDT in areas that use DST during part of the year.
Converting Central Time to Other US Time Zones
- Central Daylight Time (CDT) is 1 hour behind Eastern Daylight Time (EDT).
To convert CDT to EDT, you have to add one hour.
- Central Daylight Time (CDT) is 1 hour ahead of Mountain Daylight Time (MDT).
To convert CDT to MDT, you have to subtract one hour.
- Central Daylight Time (CDT) is 2 hours ahead of Pacific Daylight Time (PDT).
To convert CDT to PDT, you have to subtract two hours.
