Mountain Time Zone Edit

The Mountain Time Zone of North America keeps time by subtracting seven hours from Coordinated Universal Time (UTC-7) during the short days of autumn, winter and spring, and by subtracting six hours during the Daylight Saving days of spring, summer, and early autumn (UTC-6).

  • standard time: Mountain Standard Time (MST)
  • daylight saving: Mountain Daylight Time (MDT)

The zone is one hour ahead of the Pacific Time Zone and one hour behind the Central Time Zone.

In the United States, the following states are part of the Mountain Time Zone:

Additionally, the southwestern quadrant of North Dakota, the western half of South Dakota, the western third of Nebraska, the two westernmost counties in Texas, and the bulk of Idaho are part of the Mountain Standard Time Zone. Four counties in Kansas are part of the Mountain Standard Time Zone. Also, the greater part of Malheur County, Oregon and the Nevada town of West Wendover is on Mountain Time. Jackpot, Nevada observes Mountain Time unofficially because of close economic ties with southern Idaho.

In Canada, Mountain Time is observed in the province of Alberta, the Northwest Territories (except for Tungsten), the Kitikmeot Region of Nunavut and the part of Saskatchewan immediately surrounding the city of Lloydminster.
