Nepal Standard Time

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][3] it is one of only three time zones with a 45-minute offset from UTC.^{[n 1][4]}

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.^[5]
