About the Nepali Bikram Sambat Calendar
Bikram Sambat (BS) is the official calendar of Nepal and is widely used across the country for government, legal, and cultural purposes. Named after the legendary Indian emperor Vikramaditya (Bikramaditya), the calendar is a lunisolar system that runs approximately 56 years and 8 months ahead of the Gregorian calendar. This means that when it is 2026 AD in the Western world, Nepal is in the year 2082–2083 BS. The exact offset between BS and AD is not a fixed 56 or 57 years — it depends on where you are in the Nepali calendar year, since the Nepali new year begins in mid-April rather than January 1.
The Nepali New Year, known as Nava Varsha, falls on Baisakh 1st, which typically occurs around April 13–15 in the Gregorian calendar. The twelve months of the Bikram Sambat calendar each carry Sanskrit-derived names: Baisakh, Jestha, Ashadh, Shrawan, Bhadra, Ashwin, Kartik, Mangsir, Poush, Magh, Falgun, and Chaitra.
Why Month Lengths Vary in Bikram Sambat
Unlike the Gregorian calendar, where month lengths are fixed (28–31 days by rule), Bikram Sambat month lengths vary between 29 and 32 days and must be determined from official calendar tables published by Nepal's government each year. This variation arises because the BS calendar is tied to the solar year but calibrated against astronomical positions of the sun as it moves through the zodiac signs. As a result, conversion between BS and AD dates requires a lookup table rather than a simple formula — which is exactly what this converter provides, covering verified data for years 2080–2090 BS (approximately 2023–2034 AD).
Major Nepali Festivals in the BS Calendar
Most of Nepal's biggest festivals are scheduled according to the Bikram Sambat and lunar calendar. Dashain, the most important festival in Nepal, falls during the month of Ashwin (September–October) and spans fifteen days, culminating on Vijaya Dashami. Tihar (also called Deepawali or Diwali) follows in the month of Kartik (October–November) and is celebrated over five days with oil lamps, sweets, and worship of animals. Holi, the festival of colours, falls in Falgun (February–March).
Bikram Sambat vs. Nepal Sambat
Nepal also uses a second traditional calendar called Nepal Sambat (NS), which is the classical calendar of the Newar community of the Kathmandu Valley. Nepal Sambat is approximately 879 years behind Bikram Sambat and is used for Newar religious rites and festivals. For everyday civil purposes — including official documents, school calendars, and public holidays — Bikram Sambat is the standard across all of Nepal.
