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 Moscow Standard Time (MSK)
Moscow Standard Time (MSK, IANA: Europe/Moscow) is the civil time of European Russia (west of the Ural Mountains) and the Russian capital, set at UTC+3:00 year-round. Russia abolished Daylight Saving Time in 2011 (initially staying permanently on UTC+4 summer time), then in 2014 the Russian Federation Council reverted the country to permanent standard time, with Moscow on UTC+3 year-round, so MSK has been observed without seasonal change since October 2014. Russia spans 11 time zones (UTC+2 Kaliningrad to UTC+12 Kamchatka), of which MSK is the most populous and the reference time for the federal government. MSK serves the European Russia population of ~110 million across the Central Federal District (Moscow oblast, Moscow city, surrounding oblasts), Northwestern Federal District (St. Petersburg + Leningrad oblast), Southern Federal District (Krasnodar, Rostov-na-Donu, Sochi), and Volga Federal District (Nizhny Novgorod). MSK is identical in offset to East Africa Time (EAT), Saudi Arabian Standard Time (AST-SA), and EEST in summer. Major MSK cities: Moscow (12.6M), Saint Petersburg (5.4M), Nizhny Novgorod (1.2M), Kazan (1.3M), Rostov-on-Don (1.1M), Sochi (450K). Affects: MOEX (Moscow Exchange) trading hours, Roscosmos Mission Control operations from Korolev, Bolshoi Theatre performance schedules.
