Nepali official life runs on Bikram Sambat: citizenship certificates, academic transcripts, Lok Sewa forms and most government paperwork ask for dates in BS, while embassies, foreign universities and most software expect AD. Converting by hand is error-prone because BS months have no fixed lengths — a BS year can have 365 or 366 days, and each month runs from 29 to 32 days depending on the year.
This converter is built from the standard published month tables for BS 2000–2090 (AD 1943–2034), verified day by day across the full range. Select a date in either calendar and the corresponding date appears immediately, with its weekday in English and Nepali.
The Bikram Sambat calendar is roughly 56.7 years ahead of the Gregorian calendar, and its new year falls in mid-April, so the BS year containing January is different from the BS year containing May. On top of that, BS month lengths are not fixed: Baisakh can have 30 or 31 days, and shorter months vary from year to year according to the published calendar.
That is why quick rules like 'subtract 57 years' only work within part of the year and still get the month and day wrong. A converter has to know the actual length of every month in every year, which is what the built-in tables provide.
Inside Nepal, BS is the default: citizenship and passport applications, academic certificates, NEB and university records, court dates and government deadlines are all stated in BS. Outside Nepal, AD is the default: visa and embassy forms, IELTS and SAT registrations, foreign university applications and international job applications.
Students routinely need both on the same day — a transcript date in BS matched to a visa form in AD. Converting carefully matters, because a one-day mismatch between documents is a common reason applications get queried.
The converter shows the weekday alongside every converted date, in English and Nepali. This is worth checking when a deadline is stated as a day of the week, and remember that the Nepali weekly holiday is Saturday, not Sunday — a 'submit by Friday' deadline in Nepal means शुक्रबार, with शनिबार already a holiday.
This converter covers BS 2000 to 2090, which corresponds to AD 1943 to 2034 — every date a current student is likely to need, from birth certificates to graduation. Older documents, such as dates from a grandparent's citizenship record, can fall before BS 2000; for those, cross-check against a printed official Nepali calendar or the relevant office.
Yes, completely free, with no sign-up and no limit on conversions.
The converter is built from the standard published BS month-length tables for BS 2000–2090 and was verified day by day across the full range. For documents with legal effect, confirm the final date against the official Nepali calendar as well.
Open the converter — it starts on today's date in both calendars, so the BS date for today is shown as soon as the page loads.
The Nepali calendar follows astronomical calculations, so year and month lengths vary. Baisakh can have 30 or 31 days, and the total year can be 365 or 366 days — the tables account for every year individually.
No. The supported range is BS 2000–2090 (AD 1943–2034). For older dates, use the official printed Nepali calendar or confirm with the issuing office.
