About New Zealand Standard Time (NZST)
New Zealand Standard Time (NZST, IANA: Pacific/Auckland) is the civil time of New Zealand mainland (North Island + South Island), set at UTC+12:00. NZST is observed in winter; New Zealand switches to New Zealand Daylight Time (NZDT = UTC+13) from the last Sunday of September to the first Sunday of April per the Time Act of 1974 + Standard Time Act of 2007 (a slightly different DST schedule than Australia + most of the Northern Hemisphere). The Chatham Islands archipelago (Chatham, Pitt Islands — 800 km east of NZ mainland) uses Chatham Standard Time (CHAST = UTC+12:45) and Chatham Daylight Time (CHADT = UTC+13:45) — one of the world's only 45-minute-offset zones along with Nepal UTC+5:45 and Eucla WA UTC+8:45. NZST serves approximately 5.2 million New Zealanders. NZST is identical in offset to Fiji Time (FJT), Marshall Islands Time, Tuvalu Time, Wallis and Futuna Time. Major NZST cities: Auckland (1.7M metro — North Island), Wellington (210K city, 425K metro — capital), Christchurch (380K — South Island), Hamilton (180K), Tauranga (155K), Dunedin (135K), Queenstown (25K — tourist hub + Lord of the Rings filming locations). Affects: NZX (New Zealand Stock Exchange) trading hours, All Blacks rugby match scheduling, Hobbiton + Milford Sound tourism operating hours.
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.
