Drop a day into either panel and the matching date appears straight away. The converter knows every day from 2000 BS to 2090 BS and pre-fills today so you can start without typing anything.
Bikram Sambat (BS) → Gregorian (AD)
Gregorian (AD) → Bikram Sambat (BS)
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.
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.
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.
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.
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.
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.
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.
