Nepal Standard Time (NPT) is the time zone for Nepal. [1] With a time offset from Coordinated Universal Time (UTC) of UTC+05:45 all over Nepal, [2] it is one of only three time zones with a 45-minute offset from UTC. [n 1] [3]


NPT is an approximation of Kathmandu mean time, which is 5:41:16 ahead of UTC. The standard meridian passes through the peak of Gaurishankar mountain about 100 kilometres (62 mi) east of Kathmandu. [2]

Nepal used local solar time until 1920, in Kathmandu UTC+05:41:16. In 1920, Nepal adopted Indian Standard Time, UTC+05:30. In 1986 Nepal advanced their clocks by 15 minutes, giving them a time zone of UTC+05:45. [4]

ISO 8601Data elements and interchange formats – Information interchange – Representation of dates and times is an international standard covering the exchange of date- and time-related data. It is maintained by the Geneva-based International Organization for Standardization (ISO) and was first published in 1988 with updates in 1991, 2000, 2004 and 2019. The purpose of this standard is to provide an unambiguous and well-defined method of representing dates and times, so as to avoid misinterpretation of numeric representations of dates and times, particularly when data is transferred between countries with different conventions for writing numeric dates and times.

Time zone Region on Earth that has a uniform standard time for legal, commercial, and social purposes

A time zone is a designated area of the globe that observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions instead of strictly following longitude because it is convenient for areas in close commercial or other communication to keep the same time. France, including its overseas territories, has the most time zones of any country, with a total of 12.
