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 Nepal Government Calendar.

What is Bikram Sambat (BS)?

Bikram Sambat is Nepal's official national calendar, named after King Vikramaditya. It runs approximately 56 years and 8 months ahead of the Gregorian calendar. BS months are solar — each month lasts as long as the Sun takes to cross one zodiac sign, so lengths vary from 29 to 32 days and differ from year to year — which is why exact lookup tables are essential. This converter uses a verified dataset for all 91 years from 2000 to 2090 BS.

AD (Gregorian) is the internationally used calendar with fixed months (28–31 days). BS (Bikram Sambat) is Nepal's official solar calendar, running approximately 56 years 8 months ahead of AD, with variable month lengths of 29–32 days.
BS 2083 runs from Baisakh 1, 2083 (April 14, 2026) to Chaitra 30, 2083 (April 13, 2027). Most of 2083 BS falls in 2026 AD, and the last months fall in 2027 AD.
Baisakh 1, 2084 BS is Wednesday, April 14, 2027.
Nepali months have 29 to 32 days and the lengths change every year, which is why a lookup table is needed. In 2083 BS the months have 31, 31, 32, 31, 31, 31, 30, 29, 30, 29, 30 and 30 days (Baisakh to Chaitra).
Start from a known date such as Baisakh 1 of that BS year in AD (see the table above), then add the days of each full Nepali month before your date, and finally the day of the month minus one. This converter does exactly that using the verified month-length table, so you do not have to count.
