The number 13 is synonymous with bad luck. It's considered unlucky to have 13 guests at a dinner party, many buildings don't have a 13th floor and most people avoid getting married or buying a house on a day marked by this dreaded number. Especially superstitious folks even avoid driving on Friday the 13th.
