This Rare Friday the 13th

Juha-Matti Laurio writes to point out a Washington Times story about how special this particular Friday the 13th is. The digits in the numerical notation for the date add up to 13 — whether you write it in the US or the European form. From the article: "The phenomenon hasn't happened in 476 years, said Heinrich Hemme, a physicist at Germany's University of Aachen who crunched the numbers to find that the double-whammy last occurred Jan. 13, 1520."

    Perhaps not to you but Jan. 13, 1520 was the date of Johann Gutenberg's last solid crap....not something to be taken lightly, historically speaking that is....

    1520 + 476 = 1996 - now that is +5 Interesting.

    Also, from the +5 Interesting department:

    1111 + 2222 = 3333
    1010 + 101 = 1111

    and not to forget the classics

    7 * 6 = 42
