About the Nepali date converter

This tool converts dates between Bikram Sambat (BS), the official calendar of Nepal, and the Gregorian (AD) calendar used across the world. Choose the direction, enter a date, and you get the equivalent date in the other calendar along with the weekday and the written Nepali form.

Why BS and AD do not simply differ by a fixed number of years

Bikram Sambat runs about 56 years and 8 months ahead of the Gregorian year, but you cannot convert by subtracting 56 or 57 — the gap shifts through the year because the two calendars begin at different points and have different month lengths. A BS month is 29 to 32 days long, set by the traditional calendar, so each year's month lengths are stored in a table rather than calculated from a formula. This tool uses a verified lookup table for 1975–2099 BS (1918–2043 AD), which is why it stays accurate.

The Nepali year and months

The BS year begins in mid-April with the month of Baisakh. The twelve months — Baisakh, Jestha, Ashadh, Shrawan, Bhadra, Ashwin, Kartik, Mangsir, Poush, Magh, Falgun and Chaitra — do not line up with the Gregorian months, so a BS date falls in a different AD month each year. Nepali dates are often written as "2082 Mangsir 10" in official documents and in the "… साल … गते" form on certificates.

Where the converter is useful

Nepali citizenship certificates, land-registration papers, school records and many government forms carry BS dates, while passports, visas and international bookings use AD dates. The converter bridges the two — for example, to work out the Gregorian date of a BS birthday, or to fill a form that asks for the AD equivalent of a Nepali document date.

Frequently asked questions

How do I convert a Bikram Sambat date to English (AD)?

Select the BS → AD direction, enter the BS year, month and day, and the tool shows the matching Gregorian date with the weekday. For example, 2082 Mangsir 10 BS converts to 26 November 2025 AD.

How many years ahead is Bikram Sambat?

Bikram Sambat is about 56 years and 8 months ahead of the Gregorian year, but the difference is not constant, so you cannot convert by simply subtracting 56 or 57. The exact offset moves through the year, which is why a date table is needed.

Why is the Nepali calendar different from the English one?

Bikram Sambat is a lunisolar calendar: its months are 29–32 days long and are set by tradition rather than by a fixed rule, and it starts in mid-April. The Gregorian calendar is solar, so the two do not align month for month.

What is the Nepali date format?

Nepali dates are commonly written as "2082 Mangsir 10" or, in Devanagari, "२०८२ मंसिर १० गते". Official documents often add the year as "… साल".

What is the supported date range?

The converter covers 1975–2099 BS, which corresponds to 1918–2043 AD. Dates outside that range cannot be converted reliably from the built-in table.

Is Nepali New Year always in April?

Yes — the BS year begins on the first day of Baisakh, which falls in mid-April on the Gregorian calendar (usually 13 or 14 April).
