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 Western European Time (WET)
Western European Time (WET, IANA: Europe/Lisbon, Atlantic/Faroe) is the civil time during winter for Portugal mainland (excluding the Azores), the Canary Islands (Spain), the Faroe Islands (Denmark), and Iceland uses WET-equivalent year-round (no DST in Iceland). WET is set at UTC+0 — the same offset as GMT — but the distinction is that GMT refers specifically to the time at the Greenwich Observatory while WET is the formal civil-time designation in continental Western European countries. WET observes Daylight Saving Time (switching to WEST — Western European Summer Time = UTC+1) from the last Sunday of March to the last Sunday of October per EU Directive 2000/84/EC. The Azores archipelago (Portuguese Atlantic territory) is one hour behind mainland Portugal at AZOT = UTC-1:00 (winter) / AZOST = UTC+0:00 (summer). WET serves approximately 17 million people. Major cities: Lisbon (550K city, 2.9M metro), Porto (240K), Las Palmas de Gran Canaria (380K), Santa Cruz de Tenerife (220K), Reykjavík (130K — Iceland on WET-equivalent), Tórshavn Faroe (13K).
