How this converter works
Nepal's official calendar is Bikram Sambat (BS) — a lunisolar system that sits roughly 56 years and 8 months ahead of the Gregorian (AD) calendar most of the world uses. BS month lengths aren't fixed the way January or February are; they shift between 29 and 32 days each year based on astronomical calculation. That's why a straight arithmetic conversion doesn't work, and why a lookup-based tool like this one is the reliable way to translate dates.
The converter supports every day from 2000 BS to 2090 BS (1943 AD to 2034 AD) and works in both directions.
When people use this tool
- Filling passport and visa forms that ask for an English date of birth
- Preparing citizenship papers, PAN applications and other legal documents
- Formatting marriage certificates or academic records for international use
- Planning around Nepali festivals, tithis and panchanga events
- Translating old Nepali-dated paperwork inherited from family or archives
The 12 months of the Nepali calendar
A Bikram Sambat year opens with Baisakh around the middle of April, not in January. Each BS month straddles two Gregorian months, which is why a Nepali date never lines up neatly with an English one. The table below shows where each month usually falls and how long it tends to run.
| # | Month | Devanagari | Usual AD span | Days |
|---|---|---|---|---|
| 1 | Baisakh | बैशाख | mid-April – mid-May | 30–31 |
| 2 | Jestha | जेठ | mid-May – mid-June | 31–32 |
| 3 | Ashadh | असार | mid-June – mid-July | 31–32 |
| 4 | Shrawan | साउन | mid-July – mid-August | 31–32 |
| 5 | Bhadra | भदौ | mid-August – mid-September | 30–32 |
| 6 | Ashwin | असोज | mid-September – mid-October | 30–31 |
| 7 | Kartik | कार्तिक | mid-October – mid-November | 29–30 |
| 8 | Mangsir | मंसिर | mid-November – mid-December | 29–30 |
| 9 | Poush | पुष | mid-December – mid-January | 29–30 |
| 10 | Magh | माघ | mid-January – mid-February | 29–30 |
| 11 | Falgun | फागुन | mid-February – mid-March | 29–30 |
| 12 | Chaitra | चैत | mid-March – mid-April | 30–31 |
Day counts are indicative — the real length of a given month is fixed each year by astronomical calculation, so Jestha may run 31 days in one year and 32 in the next. The converter reads the actual published length for the exact year you pick rather than assuming a fixed number.

Frequently asked questions
How do I convert a BS date into AD?
Open the Nepali to English panel, pick a BS year, month and day, and the Gregorian equivalent updates instantly. Anything between 2000 BS and 2090 BS (1943 AD to 2034 AD) is supported.
What about the other way — AD into BS?
Use the English to Nepali panel, pick a Gregorian year, month and day, and you'll get the matching BS date shown in both English and Devanagari Unicode — ready to paste into any form or document.
What exactly is BS versus AD?
BS (Bikram Sambat), also called Vikram Samvat, is Nepal's national calendar. It sits about 56 years and 8 months ahead of the Gregorian calendar (AD). As a quick check: 2082 BS covers most of 2025 and the first quarter of 2026.
Can I use this to convert my Nepali birth date for a passport?
Yes — that's one of the most common reasons people reach for it. Pick the BS year, the month (Baisakh, Jestha, Ashad and so on) and the day, and the Gregorian date you need for passport, visa, citizenship or PAN paperwork appears right away.
Why does the day dropdown change when I switch months?
Nepali months don't all have 30 or 31 days like Gregorian months — they range from 29 to 32 days depending on astronomical timing each year. The day list automatically trims or extends so you can only pick days that actually exist in that month.
Can I trust the numbers?
Yes. The calendar tables are cross-checked against Hamro Patro and Nepal Patro, and every single day from 2000 BS to 2090 BS (more than 33,000 days) has been run through round-trip tests in both directions.
What are the 12 months of the Nepali calendar?
In order: Baisakh, Jestha, Ashadh, Shrawan, Bhadra, Ashwin, Kartik, Mangsir, Poush, Magh, Falgun and Chaitra. The year starts with Baisakh in mid-April, and each month spans parts of two Gregorian months.
What is the current Nepali year in Bikram Sambat?
2083 BS, which runs from April 2026 to April 2027. A new Bikram Sambat year always begins on Baisakh 1, around the middle of April rather than in January.
Why do Nepali month lengths change from year to year?
BS month lengths are set by astronomical calculation, not by a fixed rule. A month can run 29, 30, 31 or 32 days depending on the year. That is why arithmetic conversion fails and a lookup table is needed.
Which years does this converter cover?
Every day from 2000 BS to 2090 BS, which corresponds to 1943 AD through 2034 AD. That covers birth dates on virtually all Nepali citizenship certificates currently in circulation.
How is Bikram Sambat different from Nepal Sambat?
Bikram Sambat is Nepal's official civil calendar and is about 56 years ahead of AD. Nepal Sambat is a separate historical calendar that runs roughly 880 years behind AD, used mainly for cultural and Newar festival dates.
Can I get the Nepali date in Devanagari script?
Yes. Converted results are shown in both English numerals and Devanagari Unicode, so you can copy the Nepali form straight into a form, certificate or document without retyping it.
Why does my converted date differ by a day on another website?
Some sites use approximated month lengths or an older calendar dataset. This converter uses published per-year month lengths cross-checked against Hamro Patro and Nepal Patro, and passes round-trip tests in both directions.
Can I convert dates for academic certificates and transcripts?
Yes. Converting a BS issue date or date of birth into AD is a routine step when preparing transcripts, mark sheets and certificates for foreign universities, employers and immigration files.
Does the converter work on mobile without installing anything?
Yes. It runs entirely in the browser on phones, tablets and desktops. There is nothing to install, no sign-up, and no data leaves your device during conversion.
