is it st paddy's day or st patty's day?
Follow @gsbrownabc. The Dublin Airport Facebook page posted this notice clarifying that it's Saint Paddy's Day, not Saint Patty's Day. (DublinAirport/Facebook). Here's a PSA from the Dublin Airport: Don't call it St. Patty's Day. Also, March 17 should never be referred to as Patty's Day either. You may, however, call it St. Paddy's Day, or Paddy's Day. Also acceptable are the traditional St. Patrick's Day and Patrick's Day.
