Statistics Saturday: Friday the 13ths, 2017


Also you have no idea how compelling I found it as a kid that January and October started the same day of the week, as did February and November, unless it was a Leap Year in which case January started the same day as July and February the same day as August. Once more, in retrospect, I understand why everyone in middle school treated me that way.

Based on current projections.

Not valid on the Julian calendar.

Does not account for “Mercedonius”, the occasional 22-day month the Romans would sometime stick in the middle of February because they really did not have a clear handle on how to design a good calendar. I mean, they managed to screw up the rule of “leap year every four years” and it took more than a decade before anyone realized, and that isn’t even my joke.

Not counted: all appearances of King Friday The 13th during the Mister Rogers’ Neighborhood marathon as I could not find when that’s scheduled.

For 2017: January 1, February 0, March 0, April 0, May 0, June 0, July 0, August 0, September 0, October 1, November 0, December 0.
You suppose we’ll ever get a month that’s nothing but Fridays the 13th? It seems like there’s a lot of room for expansion there. I mean other than November 2016.

The index dropped a point today and everyone is hailing it as proof that a sensible diet and regular exercise work.
