Thanks are due to Carl Friedrich Gauss for coming up, in 1802, with the extremely brilliant orinigal formula, or algorithm, and to Zvi Har'El for his brilliant elucidation of the algorithm, and for giving programs, in C, and in Java. I propose to have the (generational variant of the) Java code as a part of the Halachic standard (with the required minimal substitutions, specified by the Sanhedrin). The third person to be thanked is James A. Shneer, who wrote the wonderful book The Jewish Calendar and the Torah: Introduction - 2nd Edition. I am sure the book was created with the Gauss algorithm, probably with one of the programs of Zvi Har'El. A change in Halacha would be welcomed by Shneer, I guess, as an opportunity to make a special edition of his book.
