What is the Bikram Sambat Calendar?
Bikram Sambat (BS) is Nepal's official calendar system, approximately 56.7 years ahead of the Gregorian calendar. The current BS year is 2082. Unlike the Gregorian calendar with fixed month lengths, each BS month has between 29 and 32 days, determined astronomically.
The BS calendar has 12 months: Baishakh, Jestha, Ashadh, Shrawan, Bhadra, Ashwin, Kartik, Mangsir, Poush, Magh, Falgun, and Chaitra. The new year starts on 1 Baishakh, which falls in mid-April of the Gregorian calendar.
Understanding BS and AD Date Systems
The Bikram Sambat (BS) calendar is approximately 56 years and 7 months ahead of the Gregorian (AD) calendar. For example, the year 2025 AD corresponds to 2081–2082 BS. Unlike the Gregorian calendar, which follows a purely solar cycle with fixed month lengths, the Bikram Sambat calendar is a solar sidereal calendar with month lengths ranging from 29 to 32 days, determined by astronomical calculations of the sun's transit through the zodiac signs.
Bikram Sambat is the official calendar of Nepal and is used for all government, legal, and administrative purposes. The calendar was introduced by King Vikramaditya and has been in continuous use for over two thousand years. Nepal is one of the few countries in the world that does not use the Gregorian calendar as its primary civil calendar. The new year begins on 1 Baishakh, which typically falls in mid-April of the Gregorian calendar.
When You Need Date Conversion
Date conversion between BS and AD is essential in many everyday situations in Nepal. When filling out official government documents such as citizenship certificates, passports, and land ownership papers, dates must be recorded in BS. However, international documents like visa applications, foreign university admissions, and work permits require Gregorian dates.
Birthday verification is another common need — many Nepalis know their birth date only in BS and need to convert it to AD for international purposes. Historical date lookup is useful for researchers, genealogists, and anyone trying to correlate events between the two calendar systems. Banking and financial institutions in Nepal operate on the BS calendar for fiscal years, while international transactions use AD dates, making conversion a daily necessity for businesses.
