About the Nepali Date Converter
Nepali Date Converter (Miti converter) converts dates between Bikram Sambat (BS), the official calendar of Nepal, and the Gregorian calendar (AD), instantly and in both directions. It is useful for converting a date of birth, historical Nepali dates, passport and visa dates, and dates in document translation.
How BS to AD conversion works
The Bikram Sambat calendar does not follow a fixed formula: month lengths vary from year to year. This converter uses a published BS month-length dataset for BS 2000–2090 (14 April 1943 AD – 13 April 2034 AD), the same reference data used by popular open-source Nepali date libraries, verified against known anchors such as 2000-01-01 BS = 14 April 1943 AD.
English to Nepali Date Converter (AD to BS)
To convert an English date to a Nepali date, switch the source calendar to AD, pick the year, month and day, and the Bikram Sambat equivalent appears instantly. This direction is what most people need for citizenship dates of birth, passport applications, and filling Nepali forms with English-calendar dates.
Nepali to English Date Converter (BS to AD)
To convert a Nepali date to an English date, keep BS selected as the source and choose the Nepali year, month and day, the Gregorian (AD) equivalent shows immediately. Useful for visa forms, WES/ECE credential evaluations, and translating dates on Nepali documents.
