2. Where does the Friday 13th superstition originate from?

To find the explanation for the origin of this superstition, we have to go back to ancient times. At least this is where we find the earliest negative opinion of this number; this was the time when the number 13 was first deemed unlucky. In the Norse mythology there is a story about 12 gods having a dinner together. Loki, however, was not invited; he was the 13th (uninvited) guest. Being very furious, he arranged for Höðr to shoot Balder with an arrow. Balder died, and the whole Earth got dark. 

The unlucky nature of Friday comes from two events. Firstly, historians believe that Jesus was crucified on this day. Secondly, the fall of man also happened on Friday.

In Western cultures, the superstition of Friday the 13th ingrained in everyday life so much that in the USA, for example, there are no 13th floors in buildings, and rooms with number 13 are also missing from hotels.

3. How many Friday the 13ths are there in a year?

Usually there is one Friday the 13th in a year. Sometimes, however, it happens that there are three Friday the 13ths in a year (for example in 2015).
