About Philippine Time (PHT)

Philippine Time (PHT, IANA: Asia/Manila) — also called Philippine Standard Time (PST) — is the civil time of the Republic of the Philippines, set at UTC+8:00 year-round (no DST). Philippines observed Daylight Saving Time briefly between 1936-1938 and 1942-1944 during Japanese occupation, but has remained on PHT year-round since 1944. The Philippine Standard Time Act of 2013 (Republic Act 10535) established PHILMET — the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) — as the official timekeeper, and mandated that all government clocks display synchronized PHT. PHT is identical in offset to China Standard Time (CST), Hong Kong Time (HKT), Singapore Time (SGT), Malaysia Time (MYT), Brunei Time (BNT), Australian Western Standard Time (AWST). PHT serves approximately 117 million Filipino people across 7,641 islands organized into 17 regions + 81 provinces. Major Philippine cities: Manila + NCR (1.8M city, 13.5M metro — National Capital Region also called Metro Manila is the world's most densely populated metropolitan area), Quezon City (3M — NCR), Caloocan (1.7M — NCR), Davao (1.8M — Mindanao), Cebu (1M — Visayas), Zamboanga (980K). Affects: PSE (Philippine Stock Exchange) trading hours, BPO (Business Process Outsourcing) industry shift schedules.

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.
