Mountain Standard Time Zone

From Freepedia

The Mountain Standard Time Zone (MST) is a geographic region that keeps time by subtracting seven hours from Coordinated Universal Time (UTC), resulting in UTC-7. In the United States, the following states are part of the Mountain Standard Time Zone:

• Arizona
• New Mexico
• Wyoming
• Utah
• Colorado
• Montana

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.

Arizona does not observe Daylight Saving Time, a period of time between April and October in which the rest of the Mountain Time Zone keeps time by subtracting six hours from UTC (UTC-6.) However, the Navajo Nation, the bulk of whose area is within Arizona, observes Daylight Saving Time throughout its territory.

Other parts of the world keep time by substracting seven hours from UTC:

• In Canada: the province of Alberta, the Northwest Territories, and the part of Saskatchewan immediately surrounding Maple Creek.
• In Mexico, the states of Baja California Sur, Chihuahua, Nayarit, Sinaloa, and Sonora. All these, with the exception of Sonora, observe DST from april to october.
