The Mountain Time Zone in the United States

The Mountain Time Zone (MT) is one of the four time zones in the contiguous United States. It covers the states of Arizona, Colorado, Montana, New Mexico, Utah, and Wyoming, as well as parts of Idaho, Kansas, Nebraska, Nevada, North Dakota, Oklahoma, Oregon, South Dakota, Texas, and Washington.

The Mountain Time Zone is bordered by the Pacific Time Zone to the west and the Central Time Zone to the east. The northern boundary of the Mountain Time Zone is the Canadian border, and the southern boundary is the Mexican border.

The History of the Mountain Time Zone

The Mountain Time Zone was created in 1883 as part of the General Time Act. The act established five time zones for the United States: the Eastern, Central, Mountain, Pacific, and Alaska time zones.

The Mountain Time Zone was originally much larger than it is today. It included all of the states that are now in the Mountain Time Zone, as well as parts of California, Idaho, Nevada, Oregon, and Washington.

In 1918, the Mountain Time Zone was reduced in size when the Pacific Time Zone was expanded to include California and Oregon. In 1942, the Mountain Time Zone was further reduced in size when the Central Time Zone was expanded to include parts of Kansas, Nebraska, North Dakota, and South Dakota.

The Current Boundaries of the Mountain Time Zone

The Mountain Time Zone is currently defined by the following boundaries:

* The western boundary is the 107th meridian west.
* The eastern boundary is the 102nd meridian west.
* The northern boundary is the Canadian border.
* The southern boundary is the Mexican border.

The Mountain Time Zone is six hours behind Coordinated Universal Time (UTC). This means that when it is 12:00 PM UTC, it is 6:00 AM MT.
