Rare Occurrence: Full Moon on Friday the 13th

The last time it happened was the year 2000. The next time it happens is the year 2049. 

What is it? It's the occurrence of a full moon happening on a Friday the 13th!

Of course, none of this is important unless you feel a pull for Friday the 13th to be an unusual combination. 

That 13 thing is a strong superstition. In fact, buildings built in the heyday of fear, didn't post a 13th floor!

Here's is what Wikipedia says about the 13th floor: "Reasons for omitting a thirteenth floor include triskaidekaphobia on the part of the building's owner or builder, or a desire by the building owner or landlord to prevent problems that may arise with superstitious tenants, occupants, or customers. Based on an internal review of records, Dilip Rangnekar of Otis Elevators estimates that 85% of the buildings with elevators did not have a floor named the 13th floor. Future building designers, fearing a fire on the 13th floor, or fearing tenants' superstitions about the rumor, decided to omit having a 13th floor listed on their elevator numbering. This practice became commonplace, and eventually found its way into mainstream culture and building design."

One curious horror movie delved into what would happen if there was a hidden 13th floor - "Nightmare on the 13th Floor."

Of course, on a day like today, nothing beats "Friday the 13th."

Now, we have until 2049 to make this movie - 

NOTE: Soon, I will be releasing a book entitled They Come Out At Night about all the scary things that happen at nighttime.
