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 Eastern European Time (EET)

Eastern European Time (EET, IANA: Europe/Athens, Europe/Helsinki) is the civil time during winter for Eastern European countries, set at UTC+2:00. EET serves approximately 50 million people across: Bulgaria, Cyprus, Estonia, Finland, Greece, Latvia, Lithuania, Moldova, Romania, Ukraine (partial, since 1990), and parts of Russia's Kaliningrad exclave (USZ1 = UTC+2 year-round, no DST). EET observes Daylight Saving Time (switching to EEST = UTC+3) from the last Sunday of March to the last Sunday of October per EU Directive 2000/84/EC for EU member states; Ukraine and Moldova follow the same schedule but as non-EU members independently. Major EET cities: Athens (700K city, 3.7M metro), Helsinki (660K), Bucharest (1.7M), Sofia (1.3M), Riga (615K), Vilnius (590K), Tallinn (450K), Nicosia 320K), Kyiv (3M). The Russian portion of Ukraine after 2014 may use Moscow Time (MSK = UTC+3) per Russian government decree, while the Ukrainian government continues to use EET for the entire country.
