A3H++ Theorem: Direct, Additive, and Constant Time Complexity Day-Index Algorithm

This paper presents the full mathematical formalism of the A3H++ Theorem, a highly optimizedmethod for Gregorian calendar day-indexing operating in constant O(1) computational complexity.Breaking away from historic frameworks such as Zeller's congruence, the A3H++ Theorem complet...
