How to Convert Nepal Time to Iran Standard Time
Formula
To convert Nepal Time (NPT) to Iran Standard Time (IRST): Convert NPT to IRST
About Nepal Time (NPT)
Nepal Time (NPT, IANA: Asia/Kathmandu) is the civil time of the Federal Democratic Republic of Nepal, set at UTC+5:45 — one of only three time zones in the world with a 45-minute offset (along with Chatham Islands New Zealand UTC+12:45 and Eucla Western Australia UTC+8:45). NPT does not observe Daylight Saving Time. The 45-minute offset is preserved because Nepal's central meridian (~86.5°E) is between India Standard Time (IST = UTC+5:30) and Bangladesh Standard Time (BST = UTC+6:00), and Nepal historically chose to set its civil time to the local mean solar time of the Gauri Shankar peak in eastern Nepal (a national symbolic-geography choice in 1986). The 45-minute offset has practical advantages — Nepal pilots' radio communications with regional ATC are easier to deconflict from Indian-airspace traffic clocked in IST. NPT serves approximately 30 million Nepalese people across 7 provinces. Major cities: Kathmandu (1M city, 2.7M metro — capital and gateway to Mount Everest), Pokhara (300K — gateway to Annapurna treks), Lalitpur (290K), Bharatpur (280K). Affects: Nepal Stock Exchange (NEPSE) trading hours, Mount Everest spring-summit-window climbing-permit timings, Pashupatinath Temple cremation ceremony 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.
