Everything You Need to Know About Bikram Sambat (वि.सं.) & Date Conversion

Understanding Nepal's official solar sidereal calendar, the history of King Vikramaditya, and how Bikram Sambat aligns with the Western Gregorian calendar.

1. What is Bikram Sambat (वि.सं.)?

Bikram Sambat (abbreviated as BS or वि.सं.) is the official national calendar of Nepal. Instituted by Emperor Vikramaditya in 57 BCE, it is approximately 56 years and 8.5 months ahead of the international Gregorian calendar (AD). For example, the Gregorian year 2024 corresponds to the Bikram Sambat year 2080–2081.

Government documents, birth certificates, citizenship papers, national holidays, banking systems, and official academic records in Nepal are recorded primarily in Bikram Sambat.

2. Why Do Nepali Months Have Variable Day Counts (29 to 32 Days)?

Unlike the Gregorian calendar, where month lengths are governed by fixed arbitrary rules and a quadrennial leap year (February 28/29), the Bikram Sambat calendar is governed by true solar transits (Sankranti / संक्रान्ति).

The moment the Sun passes from one zodiac sign (Rashi) to the next marks the first day (1st / १ गते) of a new Nepali month. Because the Earth's orbit around the Sun is elliptical rather than circular, the Sun travels through different zodiac constellations at varying speeds. As a result, months like Baishakh, Jestha, or Ashadh can have 31 or 32 days, while months like Poush or Magh may have 29 or 30 days depending on the year.
