Central Time

Central Time (CT) is a general term used to describe the areas that observe either the Central Standard Time (CST) or Central Daylight Time (CDT) in the United States and Canada. CT is not static but switches between CDT and CST.

Territories observing the time zone are primarily in North and Central America. It runs through several Mexican and U.S. states, as well as several Canadian provinces and Central American countries.

Countries using this time zone: Belize, Canada, Costa Rica, Guatemala, Honduras, Mexico, Nicaragua, El Salvador, United States.

Principal Cities: The largest city in the CST time zone is Mexico City in Mexico, with about 12.294 million people. Other major cities in this time zone include Chicago, Houston, Iztapalapa, Ecatepec.
