Nepali Date Converter — BS to AD & AD to BS
This Nepali Date Converter converts dates between Bikram Sambat (BS) — Nepal's official calendar — and the Gregorian (AD) calendar. The BS calendar runs approximately 56 years 8 months ahead of AD, so 2082 BS ≈ 2025–2026 AD.
All conversions use exact day-offset arithmetic anchored to the verified base: 2000-01-01 BS = 1943-04-14 AD. Every BS month length is read from pre-computed lookup tables — never estimated. Results match Hamro Patro and Nepal Government Calendar.
