Central Standard Time (CST)

Introduction

Central Standard Time (CST) is the time zone that is six hours behind Coordinated Universal Time (UTC-6). It is used during standard time in parts of North America, including the United States, Canada, Mexico, Central America, and some Caribbean islands. CST is observed from the first Sunday in November to the second Sunday in March, after which it switches to Central Daylight Time (CDT) during daylight saving time.

Time Zone History

The concept of standard time zones was introduced in the United States and Canada on November 18, 1883, by the railroads to standardize timekeeping across different regions. The Central Time Zone was established to cover the central part of North America. Over the years, the boundaries of the Central Time Zone have shifted, and some regions have opted in or out of observing daylight saving time. The Standard Time Act of 1918 officially established time zones in U.S. law and introduced daylight saving time.

Geographical Coverage

Central Standard Time is observed in several U.S. states, including Alabama, Arkansas, Illinois, Iowa, Louisiana, Minnesota, Mississippi, Missouri, Oklahoma, and Wisconsin. It is also used in parts of Canada, such as Manitoba and parts of Saskatchewan, as well as in Mexico, Central America, and some Caribbean islands.

Daylight Saving Time (DST)

Daylight saving time is observed in most areas within the Central Time Zone, switching to Central Daylight Time (CDT) from the second Sunday in March to the first Sunday in November. However, some regions, such as parts of Saskatchewan, do not observe DST and remain on CST year-round.
