Oddly enough - or perhaps if you are Firday the 13th superstitious, as expected - it turns out that on the Gregorian calendar (which spans 400 years, and then re-starts), the incidence of the 13th of a month falling on a Friday is slightly higher than occurring on any other day of the week. This was calculated in 1933 by American mathematician B.H. Brown (and imagine, he had no computers to crunch these Friday 13th numbers).
