The Central Standard Time Zone (CST) is a geographic region that keeps time by subtracting six hours from Coordinated Universal Time UTC.

In the United States, the time zone includes the entire area of the states of Alabama, Arkansas, Illinois, Iowa, Louisiana, Minnesota, Missouri, Mississippi, Oklahoma, Texas except for El Paso and Hudspeth Counties and a small portion of Culberson County, Wisconsin, western portions of Florida, Indiana, Kentucky, and Tennessee, and eastern portions of Kansas, Nebraska, North Dakota, and South Dakota.

In Canada, the time zone includes all of Manitoba, nearly all of Saskatchewan, and a slice of western Ontario, and central Nunavut.

The time zone also covers most of Mexico (not the extreme west) and the Central American countries of Belize, El Salvador, Honduras, Nicaragua and Costa Rica.

When Daylight Saving Time is in effect in the United States Canada and Mexico, many regions switch to Central Daylight Time (CDT), UTC-5.
