Palo Alto Math Tutors Wonder what the Doomsday Rule is

A doomsday date, September 5, recently passed here at the Palo Alto Math Tutoring Center. You're probably wondering what in the world this "doomsday" is and whether it affects your Palo Alto Math Tutoring Student. Let's back up to the beginning of the story. In 1973, John Conway created the Doomsday Algorithm, a way of easily finding which day of the week a specific date falls on. Once you know the algorithm, all you or your Palo Alto Math Tutoring Student needs to know a is a certain year's doomsday and you to will be able to quickly find the day of the week a day falls on. Here's are the doomsday dates you need to know. Each year, 4/4, 6/6, 8/8, 10/10, and 12/12 all fall on the same day (that year's doomsday). Furthermore, 7/11, 11/7, 9/5 and 5/9 also fall on the same day (that year's doomsday). Finally, the final day in February (or 3/0 if it makes it easier) and 1/3 (or 1/4 during every 4^th year or leap year) also land on a doomsday. This means all you or your Palo Alto Math Tutoring Student needs to do is remember these dates and this year's doomsday, and he'll be able to quickly find any date's day of the week!
