Calculation

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

History

Nepal used local solar time until the year 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. [5]
