St. Patrick’s Day is celebrated every year on 17 March. A fifth-century Romano-British missionary and bishop in Ireland, Saint Patrick (Latin: Patricius; Irish: Pádraig; Welsh: Padrig) is known as the “Apostle of Ireland” and is the primary patron saint of Ireland. The other patron saints are Brigit of Kildare and Columba.
He is venerated in the Catholic Church, the Anglican Communion, the Lutheran Churches, the Old Catholic Church, and in the Eastern Orthodox Church as equal-to-the-apostles and Enlightener of Ireland. Although St. Patrick is the patron saint of Ireland, celebrations are taking place across the world.
The feast of the Irish saint on 17 March is being celebrated from Australia to Dubai to the United States.
More than 400 landmarks in more than 50 countries are turning the appropriate color as part of Tourism Ireland’s annual Global Greening initiative. Parades and festivities are taking place across Ireland.
