What Is Central Standard Time?

Central Standard Time (CST) is the second easternmost time zone in the United States and is also used in Canada.

It covers all or parts of 20 states in the US and three provinces or territories in Canada. It is also used in Mexico and Central America.

About a third of the population in the USA live in the CST time zone. It spans from northern Canada and all the way south to Costa Rica near the equator.

In North America, Central Standard Time shares a border with Eastern Standard Time (EST) in the east and with Mountain Standard Time (MST) in the west.

Central Standard Time Zone

Central Standard Time (CST) is a standard time zone in use from the first Sunday in November to the second Sunday in March—when Daylight Saving Time (DST) is not in effect. Central Daylight Time (CDT) is used during the remainder of the year.

CST Is the Central Time Zone

In everyday usage, CST 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.

Most North American time zones also have generic terms, including Pacific Time (PT), Mountain Time (MT), Eastern Time (ET), and Atlantic Time (AT).
