About these time zones
Mountain Standard Time (MST)
Mountain Standard Time (MST) is UTC-7. Denver, Salt Lake City, Alberta and most of the Mountain region use MST in winter and Mountain Daylight Time (MDT, UTC-6) in summer. Arizona (except the Navajo Nation), Sonora, several other Mexican states, Yukon and parts of British Columbia use UTC-7 all year, so in summer they match Pacific Daylight Time.
Central Standard Time (CST)
Central Standard Time (CST) is UTC-6. Most of the central United States and Manitoba use CST only in winter and switch to Central Daylight Time (CDT, UTC-5) from the second Sunday in March to the first Sunday in November. Most of Saskatchewan, most of Mexico and much of Central America stay on CST all year.
