Accurate Bikram Sambat (BS) to English (AD) Date Converter

The Bikram Sambat (BS) calendar is the official calendar of Nepal. It is historically roughly 56 years and 8.5 months ahead of the Gregorian (AD) calendar. However, converting dates manually is incredibly difficult because Nepali months vary between 29 and 32 days depending on the specific year, completely unlike the fixed AD calendar.

How does this Date Converter work?

Our BS to AD Date Converter is powered by a massive, hard-coded lookup table containing the exact number of days for every single Nepali month from 2000 BS all the way to 2090 BS. This ensures exactly 100% accuracy matching the official Nepal Panchanga Nirnayak Samiti data.
