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.

About Brasília Time (BRT)

Brasília Time (BRT, IANA: America/Sao_Paulo) is the official civil time of Brazil's most populous regions, set at UTC-3:00 — named after the federal capital city of Brasília. BRT serves approximately 175 million people across 23 of Brazil's 26 states + Federal District including the megacities São Paulo (12M), Rio de Janeiro (6.7M), Salvador (2.9M), Fortaleza (2.7M), Belo Horizonte (2.5M), Brasília (3.1M), Curitiba (1.9M). Brazil abolished Daylight Saving Time in 2019 by Presidential Decree 9772/2019 (citing minimal energy savings and disruption costs), so BRT is observed year-round without seasonal change since then. Acre State and a small portion of Amazonas use Acre Time (ACT = UTC-5:00); the remainder of Amazonas plus Mato Grosso/Mato Grosso do Sul/Rondônia use Amazon Time (AMT = UTC-4:00); the Fernando de Noronha archipelago uses UTC-2:00. BRT affects: B3 (São Paulo Stock Exchange) trading hours, Brazilian football Série A match scheduling, and Petrobras / Vale international corporate-call timing.
