Where did St. Urho's Day come from?

St. Urho wasn’t actually created until 1956. A Finnish-American named Richard Mattson said he invented the patron saint when his coworker noticed that the Finns didn’t have a patron saint similar to the Irish St. Patrick (in reality, the Finns do have a patron saint named Henry, Bishop of Finland). Mattson and his coworker Gene McCavic wrote the “Ode to St. Urho” about how he cast frogs out of Finland with his loud voice which he got from drinking sour milk and eating fish soup. The name Urho came about because of the accession of Urho Kekkonen to the presidency of Finland in 1956; Urho in the Finnish language also has the meaning of hero or brave. In the original song, the day was supposed to be May 24, but the date was changed to March 16 to coincide with St. Pat’s, with the Finns wearing green and purple. These and other changes were made by Dr. Sulo Havumäki, a professor at Bemidji State College in Minnesota. The legend of St. Urho was changed to say rid Finland of grasshoppers using the incantation “Heinäsirkka, heinäsirkka, mene täältä hiiteen!” (“Grasshopper, grasshopper, go from hence to Hell!”), which saved the Finnish grape crops.
