Nepali date converter: BS to AD and AD to BS

How the Nepali calendar (BS) relates to AD

Bikram Sambat runs about 56 years and 8 months ahead of the Gregorian calendar. The Nepali new year, 1 Baisakh, falls in mid-April, so a BS year spans two AD years: BS 2083 runs from April 2026 to April 2027.

BS months are not fixed lengths. Each has 29 to 32 days, and the lengths change from year to year according to the published calendar, which is why a BS date cannot be converted by adding a fixed number — it needs the year's table, which this converter uses.

From BS 2084, month lengths are still projections: the official calendar is published only a few years ahead. The converter marks those dates as provisional rather than presenting them as certain.

Date of birth: converting BS to AD for forms

Your citizenship certificate gives your date of birth in BS; your passport gives it in AD. Every visa, foreign university and many online forms want the AD date — and it must match the passport exactly, so convert it once, carefully, and use the same AD date everywhere.

A CV for a job in Nepal can show the BS date; for abroad, use AD, or both. The बायोडाटा format shows the date of birth with BS or AD as you choose, and the CV maker takes either.

Age calculator in BS or AD

Enter a date of birth in BS or AD and the converter gives the age today — in years, months and days, and in total days — or the age on any other date, such as the closing date of a vacancy that sets an age limit.

Lok Sewa and many other vacancies set an age limit counted on a specific date, often the last day to apply. Check your age on that date, not today. See the current Lok Sewa vacancies for their closing dates.
