About Chile Standard Time (CLT)
Chile Standard Time (CLT, IANA: America/Santiago) is the official civil time of most of Chile, set at UTC-4:00. CLT is observed during the Southern Hemisphere winter (April to September) and Chile switches to Chile Summer Time (CLST = UTC-3:00) during the Southern Hemisphere summer (September to April) per Decreto 1.444 of 2021. Chile's DST window is opposite the Northern Hemisphere DST window because the seasons are reversed. CLT serves approximately 19 million people across Chile's 16 regions. Major cities: Santiago de Chile (5.6M city, 7M metro — capital), Valparaíso (300K), Concepción (220K), Antofagasta (390K), Temuco (290K). The Easter Island (Isla de Pascua / Rapa Nui) territory in the South Pacific uses Easter Island Standard Time (EAST = UTC-6:00) separately, switching to EASST = UTC-5:00 in summer. Magallanes region in southern Chile stays on UTC-3:00 year-round (no DST). CLT affects: Santiago Stock Exchange BCS trading, Codelco copper-mining shift coordination, and ALMA Observatory astronomical-observation scheduling in the Atacama desert.
About Mountain Standard Time (MST)
Mountain Standard Time (MST, IANA: America/Denver and America/Phoenix) is the time zone for the US Mountain region and most of Canada's Rocky Mountain provinces, set at UTC-7:00. MST is observed from the first Sunday in November to the second Sunday in March; the region switches to Mountain Daylight Time (MDT = UTC-6:00) for the remainder of the year — EXCEPT for the State of Arizona (excluding Navajo Nation), which stays on MST year-round per Arizona Revised Statutes §1-242. Major MST cities: Denver, Phoenix, Salt Lake City, Albuquerque, El Paso, Tucson, Calgary, Edmonton. MST covers Colorado, Utah, Wyoming, Montana, Idaho (most), New Mexico, Arizona, parts of Texas + Mexico (Sonora). Population ~17 million in the time zone. Affects: NORAD Cheyenne Mountain operations, Denver Mile-High Stadium NFL game scheduling, Colorado ski-resort lift-operating hours, US Bureau of Land Management permit operations, and the Mormon Tabernacle Choir broadcast schedule from Salt Lake City.
