About Pacific Standard Time (PST)
Pacific Standard Time (PST, IANA: America/Los_Angeles) is the standard time zone for the US West Coast and Canadian westernmost provinces, set at UTC-8:00. PST is observed from the first Sunday in November to the second Sunday in March per the Uniform Time Act of 1966; the region switches to Pacific Daylight Time (PDT = UTC-7:00) the rest of the year. PST is used by ~50 million people in California, Oregon, Washington, Nevada (most), British Columbia, Yukon Territory, and the Mexican states of Baja California Norte. Major cities: Los Angeles, San Francisco, San Diego, Seattle, Portland, Sacramento, Las Vegas, Vancouver BC. PST is the time zone of US tech hubs (Silicon Valley, Seattle, Vancouver) — global software-release coordination, Big-Tech corporate-earnings calls, Hollywood production schedules, and NYSE/Nasdaq market hours (PST 06:30-13:00) all reference PST/PDT. Mexico abolished DST nationwide in 2022 except for border zones, complicating Baja conversions.
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.
