Triskadekaphobia All Over Again

Those sufferers of triskadekaphobia will experience a double dose of Friday the 13th this month, and a triple dose this year. There is a Friday falling on March 13, as there was a Friday falling on February 13. And there will be another Friday falling on the 13th during November this year.

The last time Friday the 13th fell on two consecutive months was six years ago in 2009. Prior to that, it occurred in 1998. This double whammy can only occur in a February - March combination, and only during certain non-leap years. No more than three can occur during any one year.
