The state of Montana in the United States is located in the Mountain Time Zone (MT), which is seven hours behind Coordinated Universal Time (UTC). This time zone is also observed in the neighboring states of Idaho, Utah, and Wyoming, as well as parts of Colorado and New Mexico.
The Mountain Time Zone was established in 1883 as part of the General Time Act, which standardized time zones across the United States. The purpose of the act was to improve railroad transportation and communication by eliminating confusion caused by different local times.
