Central Daylight Time (CDT)

Introduction

Central Daylight Time (CDT) is the daylight saving time observed in the Central Time Zone of North America. It is five hours behind Coordinated Universal Time (UTC-05:00). The primary purpose of CDT is to make better use of daylight during the longer days of summer by setting the clocks forward one hour.

Time Zone History

Central Daylight Time was first introduced during World War I to conserve energy by reducing the need for artificial lighting. The practice was adopted following the Standard Time Act of 1918. Since then, CDT has been observed annually, with some adjustments made during World War II and other periods. The current system of starting CDT on the second Sunday in March and ending it on the first Sunday in November was standardized in 2007.
