How Bikram Sambat dates work
The Bikram Sambat calendar is the official calendar of Nepal. Its year starts in mid-April on Baisakh 1, and its twelve months (Baisakh, Jestha, Ashadh, Shrawan, Bhadra, Ashwin, Kartik, Mangsir, Poush, Magh, Falgun and Chaitra) have 29 to 32 days. Month lengths differ from year to year and cannot be calculated by a simple rule, so this converter uses a published table of month lengths for each year.
Converting a BS date to AD
Choose “BS to AD”, then pick the year, month and day. The tool gives the matching English date and weekday, for example Baisakh 1, 2083 BS in April 2026 AD. Use it for date of birth conversion and for forms that ask for the English date.
Converting an AD date to BS
Choose “AD to BS”, enter the English date and read the Nepali date with the month name and numerals, such as १ वैशाख २०८३. For official documents, always confirm important dates with the issuing office.
