Nepal Standard Time is the time zone used across the sovereign state of Nepal which sets official civil time at UTC+5:45. It is a distinctive non-integer offset from Coordinated Universal Time adopted to reflect the country's longitudinal position and national sovereignty. NST is used in public administration, transportation timetables, broadcasting schedules and by institutions across urban centers such as Kathmandu, Pokhara, and Biratnagar.
The establishment of NST followed a series of regional and international timekeeping developments, influenced by observatories and surveying projects linked to British Raj-era cartography and later Nepalese state modernization. Early timekeeping in the region referenced local mean time from observatories comparable to practices at the Royal Greenwich Observatory and the Great Trigonometrical Survey origins. Formal standardization moved through administrative reforms during the reign of the Shah dynasty and was codified amid institutional changes involving the Nepal Rastra Bank, the Nepal Government ministries, and national transport authorities. The 20th century saw alignment pressures from neighboring states including India and China, and the final legal adoption reflected diplomatic and infrastructural considerations comparable to timezone decisions in Sri Lanka and Myanmar.
NST is legally defined as five hours and forty-five minutes ahead of Coordinated Universal Time (UTC+5:45). The legal basis derives from statutes and administrative orders issued by the Government of Nepal through the responsible ministries and regulatory bodies such as the Ministry of Home Affairs and central agencies involved in standards and metrology. Time signals for NST are disseminated by national broadcasters like Radio Nepal and telecommunication regulators akin to policies enforced by the Nepal Telecommunications Authority. International recognition of NST appears in time zone databases maintained by organizations such as the International Earth Rotation and Reference Systems Service and mapping agencies used by the United Nations and the International Telecommunication Union.
Civil observance of NST affects schedules for institutions including the Tribhuvan International Airport, the Nepal Stock Exchange, and major universities like Tribhuvan University. Public holidays such as Dashain and Tihar follow NST calendars for official proclamations, and national elections administered by the Election Commission, Nepal proceed according to NST schedules. Broadcast media including Nepal Television and private broadcasters synchronize programming to NST, while transport operators such as Nepal Airlines and regional railway planners coordinate with international carriers from New Delhi and Kunming using standard time conversions. Scientific timekeeping in observatories and research centers collaborates with international facilities like Indian Institute of Astrophysics and meteorological services linked to the World Meteorological Organization.
NST is applied uniformly across the territorial extent of Nepal despite the country's east–west span across several degrees of longitude. Major urban and topographic regions—such as the Kathmandu Valley, the Terai plains near Birgunj and Bhairahawa, and highland districts adjoining the Himalayas and the Everest region—observe the same legal time. The choice of UTC+5:45 positions NST between the time zones of neighboring countries, lying east of Indian Standard Time and west of the time used in parts of China. Cartographers and geographers from institutions like the Survey Department of Nepal produce maps that mark the single national time boundary consistent with international practice observed by bodies such as the International Hydrographic Organization.
Nepal has not implemented daylight saving time; NST remains constant year-round. Proposals and debates over seasonal clock changes have appeared periodically in policy discussions among legislators in the Federal Parliament of Nepal and analysts at think tanks and universities including Kathmandu University. Comparative studies referencing seasonal time adjustments in countries such as United States and United Kingdom and regional neighbors like Iran and Israel have informed these debates, but no legislative measure to adopt DST has been enacted.
NST influences economic coordination across sectors including banking—regulated by the Nepal Rastra Bank—tourism operators serving destinations like Lumbini and the Annapurna Circuit, and cross-border trade at transit points near Raxaul and Kodari (Khasa). Synchronization with global markets requires time conversion for financial exchanges involving institutions in Mumbai, Shanghai, and London. Cultural life and religious observances timed to sunrise and sunset are coordinated using NST by temples such as Pashupatinath Temple and monasteries associated with Lumbini Development Trust. Telecommunications, logistics and software services provided by companies operating within the Kathmandu Valley integrate NST into scheduling, timestamps, and interoperability standards used by multinational firms headquartered in cities like Delhi and Beijing.
NST's UTC+5:45 offset is among the few global time zones with a 45-minute increment, distinguishing it from neighboring Indian Standard Time (UTC+5:30) and time used across China (UTC+8:00). Similar non-hourly offsets exist in zones such as Australian Central Standard Time (UTC+9:30) and Newfoundland Standard Time (UTC−3:30), while 45-minute offsets are rarer but comparable to historical adjustments in regions like Chatham Islands (UTC+12:45). International organizations and mapping services used by the United Nations and the International Organization for Standardization include NST in global time zone compilations for interoperability with systems in Tokyo, Dubai, and Moscow.
