About India Standard Time (IST)
India Standard Time (IST, IANA: Asia/Kolkata) is the civil time of the Republic of India and Sri Lanka, set at UTC+5:30 — one of the world's most populous 30-minute-offset time zones. India does not observe Daylight Saving Time per the Government of India directive (a brief DST trial in 1942-1945 during WWII was discontinued; subsequent proposals from 2010-2017 were rejected by the Indian Government citing minimal energy savings + agricultural sector disruption). IST is defined as the local mean solar time at 82.5°E longitude (passing through Shankargarh fort in Uttar Pradesh, with the reference clock at the National Physical Laboratory in New Delhi per the Indian Institute of Astrophysics). The 30-minute offset is preserved because India's east-west extent (68°E to 97°E) spans ~28° of longitude — approximately 2 hours of solar time — and the central meridian is most representative for a single unified zone. IST serves approximately 1.4 billion people in India + 22 million in Sri Lanka (Sri Lanka observes SLST = UTC+5:30, identical to IST). Major cities: Mumbai (12.5M), Delhi (16.8M, NCR 29M), Bengaluru (8.4M), Hyderabad (10M), Chennai (7M), Kolkata (4.5M), Ahmedabad (5.5M), Pune (3.1M). Affects: BSE/NSE stock exchanges, IPL Indian Premier League cricket schedules.
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.
