About Nepal Standard Time (NST)
A Fascinating Exploration of Nepal's Unique Timezone
Unlike most countries that observe hourly or half-hourly timezone offsets, Nepal Standard Time (NST) has a unique **45-minute offset** (UTC+05:45). Established in 1986, this timezone is set based on the meridian of Gauri Sankar mountain, which lies 100 kilometers east of Kathmandu. Prior to 1986, Nepal observed Kathmandu local mean time, which was UTC+05:40.
Why is Gauri Sankar the Meridian?
Mount Gauri Sankar is a prominent peak in the Rolwaling Himal range of the Himalayas, rising 7,134 meters high. The longitudinal meridian passing through Gauri Sankar (86° 15' East) is remarkably close to the center of Nepal. Basing the time on this peak ensures that the sun's highest point aligns as closely as possible to midday (12:00 PM) throughout the country.
Bikram Sambat (BS) Dates
Alongside standard timezone readings, the Mero Tool Nepal Clock displays the active Bikram Sambat (BS) date. The BS calendar is the official calendar of Nepal, running approximately 56.7 years ahead of the Gregorian calendar. The Nepali year starts in mid-April with Baisakh and ends in mid-March with Chaitra.
Global Timezones with 45-Minute Offsets
Nepal is one of only three locations in the world to utilize a 45-minute timezone offset. The others are:
- Chatham Islands, New Zealand (UTC+12:45 / UTC+13:45 in daylight savings)
- Eucla, Western Australia (UTC+08:45)
- Nepal (UTC+05:45 - applied country-wide)
