About MST

MST (Mountain Standard Time) is a standard time zone used in parts of North America, including the United States, Canada, and Mexico. The time zone offset of MST is UTC-07:00, which means it is 7 hours behind Coordinated Universal Time (UTC).

Mountain Standard Time is observed throughout the year in some regions, while other areas switch to Mountain Daylight Time (MDT) during the daylight saving period. MST is commonly used across the Rocky Mountain region and surrounding areas.

MST is followed in cities such as Phoenix, Edmonton, Calgary, and several other locations in western North America. It is one of the major time zones used across the continent.
