Convert Bikram Sambat to AD

Nepal uses the Bikram Sambat (BS) calendar for government work, citizenship, land records, exam notices and contracts, while most software and foreign documents use the Gregorian (AD) calendar. BS is about 56 years and 8 months ahead of AD, but the months do not line up neatly and a BS month can have anywhere from 29 to 32 days. That is why a fixed formula does not work and a calendar table is needed.

This converter uses the published BS calendar data for the years 2000 to 2090 BS (1943 to 2034 AD).

How to use it

Choose BS to AD and select the year, month and day from your document.
Or choose AD to BS and pick the English date.
The weekday is shown in English and Nepali, together with the date in Nepali numerals.
