The term Central Time (CT) is often used to denote the local time in areas observing either Central Standard Time (CST) or Central Daylight Time (CDT).

In other words, in locations observing Daylight Saving Time (DST) during part of the year, Central Time is not static but switches between CST and CDT.

What Is Central Time?

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

About a third of the population in the USA live in the CT time zone. It spans from northern Canada and south to Mexico near the equator.

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

What Does CT Time Zone Mean?

Unlike other time zone denominations, which have a fixed time, Central Time refers to a geographical area where the time changes twice yearly as Daylight Saving Time (DST) begins and ends. Central Standard Time is UTC-6, while Central Daylight Time is UTC-5.

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