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 Australian Eastern Standard Time (AEST)
Australian Eastern Standard Time (AEST, IANA: Australia/Sydney) is the civil time of Australia's most populous eastern states — New South Wales (NSW), Victoria (VIC), Queensland (QLD), Tasmania (TAS), Australian Capital Territory (ACT) — set at UTC+10:00. AEST is observed in winter; NSW + VIC + TAS + ACT switch to Australian Eastern Daylight Time (AEDT = UTC+11) from the first Sunday of October to the first Sunday of April. Queensland does NOT observe DST (stays on AEST year-round) — a state-level decision affirmed by referendums in 1992. AEST serves approximately 21 million Australians — about 80% of the country's population. AEST is identical in offset to Vladivostok Time (Russia), Papua New Guinea Time (PGT), Guam-Chamorro Time (CHST), and the US-territory Northern Mariana Islands. Major AEST cities: Sydney NSW (5.4M metro — largest Australian city + ASX home), Melbourne VIC (5.1M metro — 2nd-largest), Brisbane QLD (2.6M metro — 3rd-largest, on AEST year-round), Gold Coast QLD (725K — tourist coastline), Newcastle NSW (475K), Canberra ACT (450K — federal capital), Hobart TAS (250K — Tasmanian capital). Affects: ASX trading hours 10:00-16:00 AEST, Australian Cricket / AFL game scheduling, Great Barrier Reef + Sydney Opera House tourism operating hours.
