Paraskevidekatriaphobia

Posted by ubpdqn on April 13, 2012

Friday the 13 th  and the fear of it (as in the title of the post)…

In the past 50 years (from 1 January 1962 till today inclusive) there have been 86 Friday the 13th’s. There have been:

  • 86 Monday the 13 th
  • 88 Tuesday the 13 th
  • 85 Wednesday the 13 th
  • 86 Thursday the 13 th
  • 87 Saturday the 13 th
  • 86 Sunday the 13 th

There has been at least one Friday the 13 th in every year  and at most 3 Friday the 13th during this period (expected by modular arithmetic considerations as well as leap years).
