Mountain Time is a time zone in North America that is seven hours behind Coordinated Universal Time (UTC-7). It is primarily observed in the western United States and Canada, including states like Colorado, Utah, and New Mexico. During daylight saving time, which typically runs from the second Sunday in March to the first Sunday in November, the time zone shifts to Mountain Daylight Time (MDT), which is UTC-6. Mountain Time is part of the larger United States time zone system, which includes several other zones such as Eastern Time and Pacific Time. This time zone is important for scheduling activities, business operations, and broadcasting in the regions it covers.
