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 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.
