Basically,
Nepali Date to English Date: Subtract - 56 Years - 8 Months - 17 Days
English Date to Nepali: Add - 56 Years - 8 Months - 17 Days

Nepali Calendar does not have constant month days as English date has. It keeps on changing due to which we can not create a fixed algorithm and find with certainity what date or month it would be in the English date.

We need to figure out mapping of first day of Bikram Sambat (BS)'s year to equivalent Gregorian date. Now, if we do this for every date, we get the Nepali to English Date Converter.

Steps in BS to AD conversion:

Supppose, if we need to convert 2001 Ashar 6, we first need to find out the number of days that have elapsed since start of Bikram Sambat year which is (2001 Baisakh 1).

Ashar is 3rd month of BS. So number of days passed is 31+31+6-1 = 67(number of days in Baisakh + number of days in Jestha + month_of_day - 1). Where month_of_day is day of month which needs conversion. 1 is subtracted as Baisakh 1 has already included.

Add number of days elapsed to Gregorian equivalent date (13 April 1944) eg (13 April 1944) + 67 = 19 June 1944. Which is correctly converted Gregorian date of 2001 Ashar 6.
