St. Patrick's Day, also known as the Feast of Saint Patrick, is an Irish holiday celebrated on or around March 17th (considered the historical date of St. Patrick's death) in honor of St. Patrick, who ministered Christianity in Ireland during the fifth century.
Originating as a religious celebration, today St. Patrick's Day is celebrated in more countries than any other national festival, influenced greatly by the Irish diaspora (Irish and Irish descendants living outside of Ireland) in North America. In fact, until the late 20th century, St. Patrick's Day was a bigger celebration outside of Ireland than within.
Celebrations involve public parades, music, festivals, gatherings at the local bar, formal banquets, dances and the wearing of green clothing that often includes Irish top hats and shamrocks. Famous landmarks are often lit up green, green beer is served at bars and even the Chicago river is dyed green in celebration, while people often eat corned beef and cabbage and shepherd's pie.
So, here's to everyone having a Safe & Happy St. Patrick's Day, and may the luck of the Irish be with you!
