Hijri Islamic Calendar converting functions for Python
Hijri Islamic Calendar converting functions, based on an enhanced algorithm designed by Muayyad Saleh Alsadi. It can be used to implement applications, gdesklets or karamba ..etc
This algorithm is based on integer operations which that there is no round errors (given accurate coefficients) the accuracy of this algorithm is based on 3 constants (p, q and a) where p/q is the full months percentage [ gcd(p,q) must be 1 ] currently it is set to 191/360 which mean that there is 191 months having 30 days in a span of 360 years, other months are 29 days, and a is just a shift.
