What is Bikram Sambat (BS)?
Bikram Sambat (BS), also spelled Vikram Samvat, is the official national calendar of Nepal. It is named after the legendary King Vikramaditya and runs approximately 56 years and 8.5 months ahead of the Gregorian (AD) calendar. The Nepali New Year (Naya Barsha) begins on Baisakh 1, which falls in mid-April each year.
Unlike the Gregorian calendar, BS months do not have a fixed number of days — each month has 29 to 32 days depending on the year, determined by the lunar-solar cycle. This is why a lookup table is required for accurate conversion rather than a simple formula.
The BS calendar is used in all official government documents, legal contracts, public holidays, school admissions, and birth certificates in Nepal. Understanding how to convert BS to AD and vice versa is essential for visa applications, international transactions, and DV Lottery forms.
