📌 Frequently Asked Questions (FAQ)

❓ What is Bikram Sambat (BS)?
Bikram Sambat is the official calendar of Nepal. It is approximately 56 years and 8 months ahead of the Gregorian (AD) calendar. For example, 2080 BS corresponds to 2023 AD.
❓ Why do Nepali months have variable lengths (28–32 days)?
Bikram Sambat is a lunisolar calendar. Month lengths are determined by the actual moon phases and solar transit, causing variations. Our table reflects exactly those variations for every year from 2000 to 2100 BS.
❓ How to convert 2083-02-02 BS to AD?
With our converter, simply enter “2083-02-02” and click convert. The result will be “2026-05-16 AD”. This matches authoritative Nepali calendars.
❓ What date range does this tool support?
We support BS years 2000 to 2100 (AD April 1943 to April 2043). Outside this range the converter shows an error.
❓ Is this converter accepted for official use?
Yes. Our month‑length table is derived from the standard Nepali panchanga used by government offices. Many users rely on it for passport and visa applications.
