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 Iran Standard Time (IRST)
Iran Standard Time (IRST, IANA: Asia/Tehran) is the civil time of the Islamic Republic of Iran, set at UTC+3:30 — one of the world's few 30-minute-offset time zones. IRST observes Daylight Saving Time (switching to IRDT = UTC+4:30) from the last Wednesday of the Iranian month of Farvardin (~March 22) to the last Wednesday of Shahrivar (~September 22) per Iranian government calendar (the country abolished DST in 2022 then partially reinstated it for energy savings — the schedule is subject to change by Iranian Parliament Majlis decree). The 30-minute offset is preserved because Iran's central meridian is approximately 52.5°E, between UTC+3 and UTC+4 standard zones, and the Iranian Solar Hijri calendar has its own astronomical traditions for time-keeping. IRST serves approximately 88 million Iranian people across 31 provinces. Major cities: Tehran (8.7M city, 13M metro — capital), Mashhad (3.1M), Isfahan (2.2M), Karaj (1.6M), Shiraz (1.6M), Tabriz (1.6M), Qom (1.2M). Other 30/45-minute offset zones: India (UTC+5:30), Nepal (UTC+5:45), Myanmar (UTC+6:30), Newfoundland (UTC-3:30), Afghanistan (UTC+4:30), Marquesas (UTC-9:30). Affects: Tehran Stock Exchange (TSE) trading, Iranian Solar Hijri New Year Nowruz celebrations.
