How to use

Bikram Sambat months have no fixed lengths, so conversion uses the official published table of month lengths for every year from 1975 to 2099 BS. The tool counts days from a fixed anchor (1 Baisakh 1975 BS = 13 April 1918 AD) to find the exact BS date.

Example

28 April 2023 AD is 15 Baisakh 2080 BS, and 13 April 2024 AD is 1 Baisakh 2081 BS — Nepali New Year.
