Welp, and there i was pronouncing Juju's name wrong
(since latin has no 'J' or 'K' Julius Caesar was spelled "Iulius Caesar" and pronounced 'Yulias Kayzar")

Cool history

Anyways, can someone do the challenge of finding the day of the week of their birthday with any of the methods above? I want other people to learn what I have learned! Math is fun when shared with other people

1900s anchor day: Wednesday
91+11=102
102/2=51
51+11=62
62%7=6
7-6=1
Doomsday 1991 = Wednesday+1=Thursday
Closest Doomsday: 8/8 is a Thursday
+1 week = 8/15
Thursday+5 days=Tuesday

Therefore, my birthday was a Tuesday. Using the same logic, this year it will fall on a Saturday.

Awesome. Checking with other methods, and on WolframAlpha to triple-check, 8/20/1991 was in fact a Tuesday.
