Formula
To convert East Africa Time (EAT) to Iran Standard Time (IRST): Convert EAT to IRST
About East Africa Time (EAT)
East Africa Time (EAT, IANA: Africa/Nairobi, Africa/Addis_Ababa) is the civil time for East African countries, set at UTC+3:00 year-round (no DST). EAT serves approximately 320 million people across: Kenya, Tanzania, Uganda, Ethiopia, Eritrea, Djibouti, Somalia, South Sudan, Comoros, Madagascar (mainland — UTC+3), and Mayotte (French territory — UTC+3). EAT shares the same UTC offset as Moscow Standard Time (MSK), Saudi Arabian Standard Time (AST-SA), Turkey Time (TRT), and Eastern European Summer Time (EEST) — making coordination with the Middle East and Russia simple year-round. Major EAT cities: Cairo (22M metro — uses EET/CAT not EAT), Nairobi Kenya (4.4M city, 9M metro — diplomatic + UN headquarters for East Africa), Addis Ababa Ethiopia (5M city, 5.5M metro — African Union headquarters), Dar es Salaam Tanzania (5M city, 7M metro), Kampala Uganda (1.7M city, 4M metro), Mogadishu (2.6M), Khartoum (Sudan — uses CAT not EAT). Affects: Nairobi Stock Exchange (NSE) trading, Serengeti / Maasai Mara safari schedules, Kilimanjaro climbing-permit scheduling.
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.
