Denver Time Zone History

The Denver time zone has undergone several changes throughout history. It was originally established as the "Central Mountain Time Zone" and covered a wider area than it does today.

In 1918, the United States adopted the Standard Time Act, which established the current time zone boundaries. The Denver time zone was assigned to the Mountain Time Zone.

In 1966, the Uniform Time Act was passed, which standardized the start and end dates of DST. This act also established the current offset for the Denver time zone, GMT-6.
