Nepali Date Converter — BS ↔ AD
Convert a Bikram Sambat (BS) date to the English (AD) calendar, or the other way round. Nepal's official documents use BS, but passports, visa forms and universities ask for AD — this converter moves a date between the two, with the weekday. Today is …
Covers BS 2000–2083 (14 April 1943 – 13 April 2027 AD), the years whose official month lengths are settled. For dates after BS 2083, check the official calendar when it is published — the month lengths are fixed by Nepal's calendar committee about a year ahead. Results are for guidance; for a passport or visa, always check the date on your official document.
How to Use
- Pick a direction: BS → AD to turn a Nepali date into an English one, or AD → BS for the opposite.
- For BS → AD, choose the BS year, month and day — the day list adjusts itself, so a month with 29 days never offers a 30th.
- Press Convert. You get the date in both calendars, the weekday in English and Nepali, and a copy button.
Why You Cannot Convert BS to AD With a Formula
- BS runs about 56 years and 8 months ahead of AD — but the gap is 56 years in January to mid-April and 57 years after that, so subtracting 56 or 57 only gives the year, never the right day.
- A BS month has 29 to 32 days, and the length changes every year. Only the published calendar table for each year gives the exact date — that is what this converter uses (BS 2000–2083).
- The anchor is BS 2000 Baisakh 1 = 14 April 1943 AD. Every conversion counts days from that date using the table.

Frequently Asked Questions
What is today's date in BS?
It is shown at the top of this page, calculated from today's AD date. BS 2083 began on 14 April 2026 and ends on 13 April 2027.
Why does subtracting 57 from the BS year give the wrong date?
It gets the year roughly right, but the day and month can be weeks out — BS months do not line up with AD months and change length every year. On a passport or visa form, that is a wrong date of birth.
Which dates can I convert?
BS 2000 Baisakh 1 to BS 2083 Chaitra 30 — that is 14 April 1943 to 13 April 2027 in AD. It covers every date you need for a birth certificate, citizenship, passport or visa form.
Is my date sent anywhere?
No. The conversion runs entirely in your browser — nothing is uploaded or stored.
