Daily Calendar for Friday, October 13, 2023

There is no year without one Friday the 13th, and no year with more than three. This day is considered the unluckiest of days in many superstitions, unless you were born on Friday the 13th, in which case it is your lucky day. “Friggatriskaidekaphobia” is the fear of Friday the 13th. Some people don’t like the number 13, whether it’s a Friday or not. The fear of the number 13 is called “triskaidekaphobia.” Quite a few skyscrapers and hotels do not have a 13th floor (or a room 13, for that matter), and many buildings substitute 12 1/2 for 13 in their addresses. Winston Churchill wouldn’t travel on Friday the 13th, considering it too unlucky.”  Discover more fun and freaky facts about Friday the 13th!
