How does this tool work?
Convert a date between the Gregorian calendar and Nepal’s Bikram Sambat calendar within the range covered by Bethemesh’s embedded calendar table.
Bikram Sambat does not follow one fixed monthly pattern because month lengths vary from year to year. Bethemesh therefore uses an embedded month-length table for BS years 2000 through 2089 together with the known reference pair Gregorian January 1, 1944 = BS 2000-09-17. The engine counts calendar days forward or backward from that reference to produce an exact conversion inside the supported range.
