A short doc about Patrick Jane Year Calculation Feat Made by: River and RatJoe_ In The Mentalist season 3, episode 21, Patrick Jane and Lisbon go to a Criminology university for questioning. During the lesson, the teacher says: "The human brain is not a computer." As an example, she writes on the board that May 31, 1976 and asks the class what day it fell on? Patrick immediately replies monday. And the answer is correct. Well the series doesn't explain how Patrick Jane calculated it, so we use the simplest method as a basis. The simplest algorithm for calculating the year is Zeller's congruence. * Year: 1976 * Month: May (m = 5) * Day: 31 (q = 31) * Last two digits of the year: K=76 * First two digits of the year: J=19 Step 1 Step 2 19 Step 3 Step 4 h= (31+15+76+19+4−38) mod7 h=107 mod 7=2 Step 5: Determine the day of the week The result h=2h corresponds to Monday in the following scheme: 0 = Saturday 1 = Sunday 2 = Monday 3 = Tuesday 4 = Wednesday 5 = Thursday 6 = Friday Conclusion May 31, 1976, fell on a Monday. And Patrick calculated this in 1 second. 🗿 Thanks For reading our doc
