About Colombia Time (COT)
Colombia Time (COT, IANA: America/Bogota) is the official civil time of the Republic of Colombia, set at UTC-5:00 year-round. Colombia abolished Daylight Saving Time in 1993 after a brief experimental DST period (1992-1993), so COT is observed without seasonal change since then. COT serves approximately 52 million people across Colombia's 32 departments + Bogotá Capital District. Major cities: Bogotá (8M city, 11M metro — capital), Medellín (2.5M city, 4M metro), Cali (2.3M), Barranquilla (1.3M), Cartagena (1M), Cúcuta (700K), Bucaramanga (600K). COT is identical in offset to Eastern Standard Time (EST) US, Cuban Standard Time (CST-Cu), Peru Time (PET), and Ecuador Time (ECT). The San Andrés and Providencia archipelago in the Caribbean Sea (closer to Nicaragua than to mainland Colombia) also observes COT. Affects: Bolsa de Valores de Colombia (BVC) trading hours, Ecopetrol oil-pipeline operations, Café de Colombia harvest-season coordination, and Cartagena de Indias cruise-ship port arrivals scheduling.
About Mountain Daylight Time (MDT)
Mountain Daylight Time (MDT, IANA: America/Denver during DST window) is the summer-time variant of MST, set at UTC-6:00 — observed from the second Sunday in March to the first Sunday in November per the Energy Policy Act of 2005. MDT shares the same UTC offset as Central Standard Time (CST), which can cause cross-time-zone scheduling confusion during the DST transition windows in March and November. The Navajo Nation in northeastern Arizona does observe MDT (unlike the rest of Arizona), creating one of the rare US sub-state time-zone exceptions per the Navajo Nation Council's 1968 resolution. MDT applies in Colorado, Utah, Wyoming, Montana, Idaho east, New Mexico, parts of Texas, and Canadian Rocky Mountain provinces (Alberta, eastern BC). Used in coordination of: Denver International Airport flight operations, ski-area lift hours during shoulder-season DST window, Yellowstone National Park ranger schedules, US National Renewable Energy Lab operations, and FAA Albuquerque ARTCC ATC operations.
