The Rainman Algorithm

Chris Brown kündigt unter The Rainman Algorithm ein Buch zur Wochentagsberechnung an:

I will teach you how to calculate what day of the week a birthday landed on, what day they’ll turn 65 and what day their birthday lands on during the present year. But don’t feel intimidated since I plan to make it under 52 pages. The method will probably take 8 pages filled with pictures and diagrams. The goal is to be able to teach ANYBODY this method. The method brings me to the answer in less than 8 seconds just about every time, I’ve broken it down so you’ll be able to do it this just as quickly if you put enough practice into it. My method is extremely simple and short. Most methods use a lot of math and a lot of steps, mine only used 3 steps and addition/subtraction.

Ich schrieb ihm vor ca. einem Monat:

Since there are the FOUR factors day, month, century and year in the century it may be an issue in your statement. The ONLY published method ever melting century and year offset mental together you will find in my book "Encyclopedia of Weekday Calculation". I'm looking forward hearing from you.
