OttoeMezzo "Secret Files"

OttoeMezzo published in August 2011 his ebook "Secret Files" with the routine " A Day for any Date Improved". The routine is based on a very clever method.

OttoeMezzo's ebook is very good written and I really liked his writing style and his clever methods. I'm looking forward to see what clever ideas OttoeMezzo will come up with in the future....

I'm very sorry but OttoeMezzo is not the first using the approach written in his "Secrets Files". So I must disappoint OttoeMezzo - he independent developed his great method.

I cover this approach in chapter "2.6.1. Decade and Year in the Decade", pp. 62-66, of my book "Encyclopedia of Weekday Calculation". Because this encyclopedia is written in German the content is known only to insiders.

OttoeMezzo's approach of separating years into decades and years in the decade was first published by the Russians L. T. Sakharosky and W. W. Sokolov in 1957 and 1966. About 50 years later the German Eisele, the Indian Divasli, the Amerians YingKing Yu and Strooke developed similiar methods.

In 2010 Chamberlain Fong published his version. This version is identical with OttoeMezzo's version. You will get identical results. The only difference is that Fong suggests to memorize the ten decades codes instead of calculation by his formulae. OttoeMezzo suggests use of simple formulaes.

Of course I will cite OttoeMezzo's method in my Encyclopedia as a version of Fong's method and as a remarkable source.

Mit Mike Daniels hatte ich einen regen Gedankenaustausch zur Wochentagsberechnung.

Michael Daniels publizierte unlängst sein neues eBook Speed Dating by Lybrary.com.
Mike beschreibt darin die Anwendung der klassischen Wochentagsberechnung in Kombination mit Bernard Zufalls Mnemonik für die Jahresschlüsselzahlen.
Mike zitiert darin lobend mein Buch "Enzyklopädie der Wochentagsberechnung".
