ABOUT BIKRAM SAMBAT
Nepali calendar and Gregorian calendar
Bikram Sambat is widely used in Nepal for everyday dates, public records, business, cultural events, and festivals. Its months do not follow the same fixed pattern as Gregorian months, so direct year subtraction is not enough to obtain an exact equivalent date.
That is why a proper date converter uses calendar data rather than a simple “56 or 57 years” shortcut. For important official matters, always compare the converted result with the date required by the receiving institution or document.
