About Nepali Date Converter Calculator

The Bikram Sambat year runs from about 14 April and sits 56 or 57 years ahead of the Gregorian year, and the day is placed using typical month lengths. Bikram Sambat month lengths vary between years because they are solar-sidereal, so this arithmetic version is an approximation and an official patro should be checked for legal dates.

Formula

Year offset

BS year = Gregorian year + 57 on or after 14 April, otherwise + 56
