Based on an enhanced algorithm designed by me
the algorithm is discussed in a book titled "ﺢﺗﻯ ﻻ ﻥﺪﺨﻟ ﺞﺣﻭﺭ ﺎﻠﻀﺑﺎﺑ"
(not yet published)

This file can be used to implement apps, 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's 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.

Portions of this algorithm is based on that found on GNU EMACS
the difference is that this algorithm does not set
all months to a fixed number of days (in the original algorithm
first month always have 30 days)
