Adoption History & Astronomical Facts
Year Established: 1986
Adopted by royal decree in 1986 to anchor national time to the sacred peak of Mount Gauri Sankar (86° 15' East), located approximately 100 kilometers east of Kathmandu. Before 1986, Nepal used a local solar offset of UTC+5:40 based on Kathmandu observatory readings.
Nepal is one of only two sovereign nations in the world with a 45-minute fractional time offset. Walking across the open southern border from India (UTC+5:30) into Nepal requires adjusting your watch forward by exactly fifteen minutes.
Frequently Asked Questions about NPT
Why is Nepal Time offset by 45 minutes instead of a full hour?
Nepal chose UTC+5:45 in 1986 so that national standard time would align precisely with the local solar noon of Mount Gauri Sankar, a revered Himalayan summit lying at 86° 15' East longitude.
What is the time difference between Nepal and India?
Nepal is exactly 15 minutes ahead of India. When it is 12:00 noon in New Delhi or Mumbai (IST, UTC+5:30), it is 12:15 PM in Kathmandu (NPT, UTC+5:45).
Does Nepal observe Daylight Saving Time?
No. Nepal stays on UTC+5:45 throughout the entire year without any daylight saving adjustments.
