Events are reported and most television networks air their shows using EST. Since the capital of the United States and its biggest city are located in the EST, it is the official time that is used in the United States. ‘EST’ is UTC-4 or UTC-5 and is based on the mean solar time of the 75th meridian west of the Greenwich Observatory. It also includes the Canadian provinces of Alberta, British Columbia, and the Northwestern Territories. Large cities that are in the MST include Phoenix, Arizona and the states of Colorado, New Mexico, Wyoming, Utah, Idaho, Oregon, North Dakota, Nebraska, Texas, Kansas, Nevada, and Montana. It is one hour ahead of Pacific Time Zone and one hour behind Central Time Zone. ‘MST’ is UTC-7 or UTC-6 and is based on the mean solar time of the 105th meridian west of the Greenwich Observatory.

In the United States and Canada, this is called Mountain Time (MT) or Mountain Standard Time (MST) at standard time and Mountain Daylight Time (MDT) at daylight savings time. In North America, there is also the Mountain Time Zone (MTZ) during the shortest days of autumn and winter. Along the east coast of North America this is called the Eastern Standard Time (EST) during winter and Eastern Daylight Time (EDT) during summer. The Western hemisphere has the Eastern Time Zone (ET), also known as the North American Eastern Standard Time (NAEST).

‘Standard time’ zone is changed to ‘daylight savings time’ zone or ‘summer time’ zone during summer which is typically standard time plus one hour. Time zones are adjusted when seasons change. There are 24 main time zones that are based on the Coordinated Universal Time (UTC) or the Greenwich Mean Time (GMT). The earth’s time zone is bounded by longitudinal lines that have uniform standards or local time. While it is nighttime in one end, it is daytime in another. The largest city in the Mountain Time Zone is Phoenix, Arizona the Phoenix metropolitan area is the largest metropolitan area in the zone.We all know that earth is a sphere and that it rotates on its axis around the sun so different places have different time zones. The Navajo Nation, most of which lies within Arizona but extends into Utah and New Mexico (which do observe DST), does observe DST, although the Hopi Reservation, as well as some Arizona state offices lying within the Navajo Nation, do not. Sonora in Mexico and most of Arizona in the United States do not observe daylight saving time (DST), and during the spring, summer, and autumn months they are on the same time as Pacific Daylight Time. In some areas, starting in 2007, the local time changes from MST to MDT at 2 am MST to 3 am MDT on the second Sunday in March and returns at 2 am MDT to 1 am MST on the first Sunday in November. In the US and Canada, the Mountain Time Zone is to the east of the Pacific Time Zone and to the west of the Central Time Zone. In Mexico, this time zone is known as the tiempo de la montaña or zona Pacífico ('Pacific Zone').

The term refers to the Rocky Mountains, which range from British Columbia to New Mexico.

Specifically, it is Mountain Standard Time ( MST) when observing standard time, and Mountain Daylight Time ( MDT) when observing daylight saving time. In the United States and Canada, this time zone is generically called Mountain Time ( MT). DST is observed in some of this time zone.
