Trick For Predicting Friday the 13th

Friday the 13th is considered a very unlucky day as we all know. Beyond bad luck, there are some movies that seem to suggest a masked villain will also run around the neighborhood hacking everyone to pieces, but I digress. How can you predict when one of these dastardly days will come? It is simple. Pay attention to the first day of the month. If it begins on a Sunday, there will be a wicked Friday of the 13th.
