Guinness sells 10 million glasses of beer daily (but no green beer) and far more on St. Patrick's Day. That's a new phenomenon. Not long ago, all pubs in Ireland closed on St Patrick's Day.
In fact, all the pubs closed on St. Patrick's Day in Ireland. Families attended church and later went for a walk or worked in the garden.
The holiday was exactly that, says Carmel McCaffrey: a holy day.
"When I was a child in Ireland, the pubs didn’t even open. It was a holy day. We went to church," the Irish scholar and former Johns Hopkins professor said in a phone interview from Maryland. "We'd usually just meet up with friends and have a meal. There were no drinks."
