Nepali Date Converter (BS ↔ AD)

Pick a date in either panel and its equivalent on the other calendar shows up at once. The converter knows every day from 2000 BS to 2090 BS and starts on today's date, so there is nothing to set up before you begin.

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 the rest of the world keeps. BS months are not fixed lengths the way Gregorian months are; each one runs between 29 and 32 days depending on astronomical calculation for that year. Because of that, a simple arithmetic formula will not give the right answer, which is why a lookup-driven tool like this one is the dependable way to move dates across.

The converter handles every day from 2000 BS to 2090 BS (1943 AD to 2034 AD) and works in both directions.

BS, or 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 sense check, 2082 BS spans most of 2025 and the start of 2026.

Yes, that is one of the most common reasons people use it. Select the BS year, the month such as Baisakh, Jestha or Ashad, and the day, and the Gregorian date you need for passport, visa, citizenship or PAN paperwork appears immediately.

Nepali months do not all have 30 or 31 days like Gregorian ones. They range from 29 to 32 days depending on the astronomical timing for that year, so the day list trims or extends to show only days that genuinely exist in that month.

Yes. The calendar tables are cross-checked against widely used Nepali calendars, and every single day from 2000 BS to 2090 BS, more than 33,000 dates, has been put through round-trip tests in both directions.
