How did St. Patrick die?
In checking a few Saint Patrick sources they tend to agree that dear St. Paddy died around the year 493 AD. The date of his death is most often given as March 17, a day we Irish celebrate to great excess inviting all to be Irish for a day and join in the festivities. For more about the life of dear St. Patrick you might check out the New Advent website, an online Catholic Encyclopedia, and Wikipedia. Google them and they’ll come up.
