Friday the 13th?

I'm not really superstitious so don't believe this day holds any spells on our destiny, (But then again, it's not over yet as I post this - sitting in So Utah, overcast and 40 degrees outside - don't think I'll bike ride today, not because it being Friday the 13th, but because it's too cold. ) But for those who are and who may really care, you need to be concerned, there are two more Friday the 13th's this year; March and November. Interestingly, or not, last year we only had one Friday the 13th to endure all year, in June, and next year there will be only one, in August. So plan your trips accordingly :-) Hmmm, the more I think about it ~ I think I'll stay inside today and enjoy the book I'm currently reading, American Creation, history of the key events in the founding of our country. I'll let you know if any infamous calamities occurred on a Friday the 13th. (Come to think of it we started with 13 colonies which became 13 states. This can't be an unlucky number and there's 13 in my immediate family - counting the pets.)
