About MST – Mountain Standard Time

Mountain Standard Time is observed in the Western part of central US and Canada, as well as the North West corner of Mexico. It is 7 hours behind UTC and turns into MDT in the summer. The name Mountain Time comes from it covering the Rocky Mountains in Western United States. In Mexico, this time zone is known as Zona Pacifico (Pacific Zone).

In the US, Arizona, Colorado, Montana, Utah and Wyoming are all observing Mountain Time but there is also a bunch where part of the state observe MST and part another time zone, like CST or PST.

In Mexico, it is only the states in the north western corner of the country, including Baja California, Sinaloa and Chihuahua that observe MST.

Daylight Saving Time

Aside from Arizona and the Mexican state of Sonora, all other locations do observe DST, turning MST into MDT – Mountain Daylight Time. Given this, and the fact that not entire states observe the same time zone, it is always recommended to use a good time zone converter to convert specific locations’ times.

About PDT - Pacific Daylight Time

Pacific Daylight Time is the time of the Western United States and Canada and is typically abbreviated as PDT. It is 8 hours behind GMT. Although PDT is for the Western part of the US and Canada it is not the Westernmost – both Hawaii and Alaska are on their own time zones due to their location.

Common locations

Pacific Daylight Time is for the Western US and Canada and thus include locations such as Vancouver, Seattle, San Francisco and Los Angeles. It also extends halfway down Baja California in Mexico. In addition to California and Washington also Nevada and Idaho are on PDT in the summer.

Daylight Saving Time

PDT is only used in the summer months so you will need to pay attention to when the switch takes place. Daylight Time is in the Pacific area observed from November to March and is one hour ahead of Pacific Standard Time.
