What is Bikram Sambat (BS)?

Bikram Sambat is the official solar calendar of Nepal, currently about 56–57 years ahead of the Gregorian (AD) calendar. Its New Year, 1 Baishakh, usually falls around April 13th–15th in the Gregorian calendar.

Why do Nepali month lengths change every year?

Unlike the Gregorian calendar, Bikram Sambat months don't follow a fixed 30/31-day pattern — each year's month lengths are set independently (typically 29 to 32 days), so converters need a reference table rather than a simple formula.

What date range does this converter support?

This tool covers Bikram Sambat years 2000 through 2090, which corresponds to April 1943 through April 2034 in the Gregorian calendar.

Note: Nepali New Year (1 Baishakh) usually falls on April 13th, 14th or 15th. Month lengths vary year to year in the official Nepali calendar, so this tool uses a reference table of published month lengths covering BS 2000–2090. Years more than a year or so ahead are projections and may shift by a day once officially published.
