What is so special about St. Patrick’s Day? Why is “everybody” Irish for this one day each year. Some ice cream stores give out free ice cream if a customer is wearing green on that day. In Ireland for centuries all pubs closed for the day of the great saint. Boston, New York, Philadelphia and other cities in the United States have parades to honor the man. It is hard to think of another country that has such a famous saint to represent them or who has been so passionately celebrated as Saint Patrick. Ever wonder why?
