National ShamrockFest, also commonly referred to as ShamrockFest, is a one-day music festival held in Washington, D.C. to celebrate Saint Patrick's Day. ShamrockFest is held in a very large, paved, parking-lot type of area at Robert F. Kennedy Memorial Stadium called the RFK Stadium Festival Fairgounds. (The festival is not held inside the stadium itself.) The festival is held on a Saturday near Saint Patrick's Day, typically from about 1pm to 9pm. The festival goes on regardless of weather, which can often be cold and rainy in Washington, D.C. in March. Typically, about 50 artists perform on approximately 7 stages for an audience of about 40,000 attendees. Though some emphasis is placed on Celtic music and other folk music, rock artists also perform at ShamrockFest.
