Mountain Time is one of the nine official time zones in the United States and Canada. It is the time zone that is used in a few states, including Arizona, Montana, New Mexico, and parts of Texas. But what exactly is Mountain Time, and where does it begin?
Understanding Mountain Time
Mountain Time is the official time zone used by several states in the western and southwestern United States. It is also used in select areas of Canada. The Mountain Time Zone is two hours behind Coordinated Universal Time (UTC) in the winter and one hour ahead in the summer. In the United States, Mountain Time is the same as Pacific Time, except during Daylight Saving Time when it is one hour ahead.
Mountain Time is also known as Mountain Standard Time (MST) when observing standard time and Mountain Daylight Time (MDT) when observing daylight saving time.
Where Does Mountain Time Begin?
Mountain Time begins in the western United States, specifically in the states of Arizona, Montana, New Mexico, and parts of Texas. The area of the United States in which Mountain Time is used is referred to as the Mountain Time Zone. This zone includes parts of the states of Arizona, Colorado, Montana, New Mexico, Texas, Utah, and Wyoming, along with parts of Canada.
Mountain Time also includes parts of Mexico, Central America, and South America. In some countries, such as Mexico and Costa Rica, Mountain Time is referred to as Central Time.
Time Zones in the United States
The United States is divided into nine official time zones. These time zones are:
- Eastern Time (ET)
- Central Time (CT)
- Mountain Time (MT)
- Pacific Time (PT)
- Alaska Time (AKT)
- Hawaii-Aleutian Time (HAT)
- Samoa Standard Time (SST)
- Chamorro Standard Time (ChST)
- Bering Standard Time (BST)
Each time zone is one hour apart from the next. Mountain Time, for example, is two hours behind Eastern Time and one hour ahead of Pacific Time.
Daylight Saving Time
Daylight Saving Time (DST) is a practice that is used to conserve energy and make better use of daylight. During DST, clocks are set one hour ahead of standard time. This means that Mountain Time is one hour ahead of Pacific Time during DST.
Daylight Saving Time is observed in most states in the United States, though some states do not observe it. States that do not observe DST include Arizona, Hawaii, and parts of Indiana, Michigan, and Texas.
