Fact of the Day:
March 17 of the year 461 is the day when Saint Patrick died- probably. But it is definitely his feast day.
He did not chase snakes, and was more associated with blue than green, but he was a missionary. His work building churches in Ireland led to his being named the patron saint of Ireland.
