Actually, though, the reason that the average person chooses to have their corned beef at this time, if they have it at all, is because the corned beef is at the store leading up to that day. The same way that turkey's are there before Thanksgiving. And, generally for less.
I remember when everyone wore something green on St. Patrick's Day. That started way back in grade school. I cont. it when my children were born, but not anymore.
