LIFESTYLE Time Zoned: what makes the Mountain Time Zone so unique?

7 min

Often overlooked and underappreciated, the Mountain Time Zone is truly one-of-a-kind.

The Mountain Time Zone, as the name suggests, is not only a geographical concept, but also a journey through time. Interlaced with majestic peaks, cascading rivers, and thriving urban hubs, this distinctive region stretches across an extensive portion of North America, offering a blend of timeless beauty and a particular pace of life that can only be experienced here.


Mountain Standard Time (MST) is the time zone that falls seven hours behind Coordinated Universal Time (UTC-7). However, during daylight saving time, usually from the second Sunday in March to the first Sunday in November, it advances to become Mountain Daylight Time (MDT), which is six hours behind Coordinated Universal Time (UTC-6).

A vast time zone

The Mountain Time Zone is mainly observed in the western part of North America. It encompasses several US states, including Arizona, Colorado, Idaho, Montana, New Mexico, Utah, and Wyoming. In these areas, it covers everything from arid deserts to soaring mountain ranges. It’s worth noting that Arizona doesn’t observe daylight saving time, so the state maintains MST throughout the year.

Heading north, the Mountain Time Zone includes parts of Canada. The provinces of Alberta, British Columbia, Northwest Territories, Nunavut, and Saskatchewan partially observe Mountain time. To the south, the Mexican states of Baja California Sur, Chihuahua, Nayarit, Sinaloa, and Sonora also follow this time zone. 

Home to multiple time zones

Within the Mountain Time Zone, there are places that don’t observe daylight saving time, and others that do. This dual nature makes it unique, especially when crossing from one region to another. 

The zone is home to both the hottest (Death Valley, California) and coldest (Rogers Pass, Montana) recorded locations in the United States. New Mexico, known as the ‘Land of Enchantment’, is entirely within the Mountain Time Zone. It’s renowned for its rich culture, arts, and historical sites, such as the ancient Pueblo structures at Chaco Culture National Historical Park.

What makes the Mountain Time Zone so unique? It’s the vast array of landscapes, cultures, and experiences it encompasses. From the rugged peaks of the Rockies, through the vibrant cultures of New Mexico and Alberta, to the serene beaches of Baja California Sur, the Mountain Time Zone is a mosaic of unique experiences, offering a beautiful blend of nature’s extremes. It represents a tapestry of the world’s most diverse environments, wildlife, and cultures, strung together by the invisible thread of time.



A zone beyond time

The Mountain Time Zone isn’t just a system of measuring time; it’s a region of cultural, historical, and geographical significance. Its story is intertwined with the development of the modern world, the establishment of global communication, and the growth of transportation. It encompasses diverse landscapes, from mountain peaks to desert plains, and houses a rich blend of cultures and communities. Often overlooked and underappreciated, Mountain time is truly one-of-a-kind.
