Defy Superstition Day takes place on September 13, 2017. A good way to participate in Defy Superstition Day is breaking superstitions to prove that they are not real. For example you could open an umbrella inside a room, walk through a ladder or let black cats cross your way. When Defy Superstition Day is on a Friday, 13 you have one extra superstition to break if you just ignore that fact.
If you are not that rational type of person you might like to use Defy Superstition Day to overcome your fear from ill luck. Superstitions are widely spread over all continents. In some hotels the 13th floor is missing to avoid bad luck. Superstitions can be a nice joke but if they abridge your way of living too much, the fear of superstitions can become a severe burden.
