If it is Corned Beef that you want on St. Patrick's Day and you're Catholic, you'll be able to eat it and enjoy it with a clear conscience, even though it's lent.
That's because several Bishops are allowing their congregations to eat meat Friday in celebration of the holiday.
Typically, for the 40-days before Easter known to Catholics as lent, eating meat is prohibited on Fridays. But Corned Beef is associated with the Irish Culture, and so some church leaders are bending the rules a little.
But if you do pig out on meat Friday, you will have to choose another day during Lent to avoid eating meat.
