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.
About West Africa Time (WAT)
West Africa Time (WAT, IANA: Africa/Lagos, Africa/Kinshasa) is the civil time for West African and Central African countries, set at UTC+1:00 year-round (no DST). WAT serves approximately 350 million people across: Algeria, Angola, Benin, Cameroon, Central African Republic, Chad, DR Congo (western half), Republic of Congo, Equatorial Guinea, Gabon, Niger, Nigeria, São Tomé and Príncipe, Tunisia. WAT is the same offset as Central European Time (CET) in winter, easing African business coordination with Western European partners. Major WAT cities: Lagos Nigeria (15M metro — the largest city in Africa and home to one of the world's fastest-growing populations), Kinshasa DRC (17M metro), Algiers (3.7M metro), Tunis (2.4M metro), Yaoundé (2.8M), Douala (2.7M), Brazzaville (1.8M), Luanda (8M metro), N'Djamena (1.4M). The eastern half of the DRC uses Central Africa Time (CAT = UTC+2). Affects: Nollywood film-industry production in Lagos, African Union meetings, Lagos NGX (Nigerian Exchange Group) trading hours, and Lagos-São Paulo + Lagos-Buenos Aires Atlantic-shipping schedules.
