About Alaska Standard Time (AKST)
Alaska Standard Time (AKST, IANA: America/Anchorage and America/Juneau) is the time zone for most of the State of Alaska, set at UTC-9:00. AKST is observed from the first Sunday in November to the second Sunday in March per the Uniform Time Act of 1966 + Energy Policy Act of 2005; Alaska switches to Alaska Daylight Time (AKDT = UTC-8:00) for the remainder of the year. The vast Alaska time zone covers ~3,200 km east-to-west — from Ketchikan to Atka in the Aleutians — and is the only US time zone that spans more than 1,000 miles longitudinally, meaning solar-noon in different Alaska cities varies by over an hour from local clock time. Major population centers: Anchorage (~290,000), Fairbanks (~95,000), Juneau state capital (~32,000). Used in coordination of cruise-ship schedules through the Inside Passage, North Slope oil-pipeline operations, US Air Force JBER and Eielson AFB activities, and Alaska commercial fishing season openings managed by ADF&G.
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.
