My St. Patrick's Day miracle is getting through it without wearing anything green...though it is said it should be blue anyway, which I'll point out to any who attempt to harass me today:
Americans have been celebrating St. Patrick’s Day since the 1850′s. But if you’re knowledge of Irish history only goes as deep as a mug of green beer you might be surprised to learn that in Ireland this holiday is not celebrated as wildly as in the U.S. and that there is not a historic connection between green and St. Patrick.
It is only in modern times that green has become associated with St. Patrick’s Day. Blue, not green, is the color long associated with St.Patrick.-source
