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 Hong Kong Time (HKT)
Hong Kong Time (HKT, IANA: Asia/Hong_Kong) is the civil time of the Hong Kong Special Administrative Region of the People's Republic of China, set at UTC+8:00 year-round (no DST). Hong Kong observed Daylight Saving Time intermittently between 1941-1979 but discontinued the practice in 1979 to better align with regional trading partners. HKT is identical in offset to China Standard Time (CST), Macau Time (MOT), Singapore Time (SGT), Philippine Time (PHT), Australian Western Standard Time (AWST), Malaysia Time (MYT). HKT serves Hong Kong's approximately 7.4 million residents in one of the world's most densely populated and economically dynamic territories (Hong Kong Island, Kowloon, New Territories, Lantau Island, and 263 outlying islands). Major Hong Kong districts: Central + Western (financial district), Wan Chai, Causeway Bay, Tsim Sha Tsui, Mong Kok, Sha Tin, Tuen Mun. Despite Hong Kong's small geographic size (1,114 km²), it is the world's 4th-largest financial center after New York, London, Singapore per Z/Yen GFCI rankings. Affects: HKEX (Hong Kong Stock Exchange) trading hours 09:30-16:00 HKT, Hong Kong International Airport at Chek Lap Kok flight operations, MTR + Star Ferry public transit schedules, and Hong Kong horse-racing at Happy Valley + Sha Tin race-courses.
