Saint Patrick's Day, or the Feast of Saint Patrick, is a cultural and religious celebration held on 17 March, the traditional death date of Saint Patrick (c. AD 385–461), the foremost patron saint of Ireland.
Saint Patrick's Day was made an official Christian feast day in the early 17th century and is observed by the Catholic Church, the Anglican Communion (especially the Church of Ireland), the Eastern Orthodox Church, and Lutheran Church. The day commemorates Saint Patrick and the arrival of Christianity in Ireland, and celebrates the heritage and culture of the Irish in general. Celebrations generally involve public parades and festivals, céilithe, and the wearing of green attire or shamrocks. Christians also attend church services and the Lenten restrictions on eating and drinking alcohol are lifted for the day, which has encouraged and propagated the holiday's tradition of alcohol consumption.
Saint Patrick's Day is a public holiday in the Republic of Ireland, Northern Ireland, the Canadian province of Newfoundland and Labrador, and the British Overseas Territory of Montserrat. It is also widely celebrated by the Irish diaspora around the world, especially in Great Britain, Canada, the United States, Argentina, Australia, and New Zealand. Saint Patrick's Day is celebrated in more countries than any other national festival. Modern celebrations have been greatly influenced by those of the Irish diaspora, particularly those that developed in North America. In recent years, there has been criticism of Saint Patrick's Day celebrations for having become too commercialized and for fostering negative stereotypes of the Irish.
On St Patrick's Day it is customary to wear shamrocks and/or green clothing or accessories (the "wearing of the green"). St Patrick is said to have used the shamrock, a three-leaved plant, to explain the Holy Trinity to the pagan Irish. This story first appears in writing in 1726, though it may be older. In pagan Ireland, three was a significant number and the Irish had many triple deities, a fact that may have aided St Patrick in his evangelization efforts.
The color green has been associated with Ireland since at least the 1640s, when the green harp flag was used by the Irish Catholic Confederation. Green ribbons and shamrocks have been worn on St Patrick's Day since at least the 1680s. The Friendly Brothers of St Patrick, an Irish fraternity founded in about 1750, adopted green as its color. However, when the Order of St. Patrick—an Anglo-Irish chivalric order—was founded in 1783 it adopted blue as its color, which led to blue being associated with St Patrick. During the 1790s, green would become associated with Irish nationalism, due to its use by the United Irishmen. This was a republican organization—led mostly by Protestants but with many Catholic members—who launched a rebellion in 1798 against British rule. The phrase "wearing of the green" comes from a song of the same name, which laments United Irishmen supporters being persecuted for wearing green. Throughout the 19th and 20th centuries, the color green and its association with St Patrick's Day grew.
The wearing of the 'St Patrick's Day Cross' was also a popular custom in Ireland until the early 20th century. These were a Celtic Christian cross made of paper that was "covered with silk or ribbon of different colors, and a bunch or rosette of green silk in the center".
In recent decades, St Patrick's Day celebrations have been criticized, particularly for their association with public drunkenness and disorder. Some argue that the festivities have become too commercialized and tacky, and have strayed from their original purpose of honoring St Patrick and Irish heritage.
St Patrick's Day celebrations have also been criticized for fostering demeaning stereotypes of Ireland and Irish people. An example is the wearing of 'leprechaun outfits', which are based on derogatory 19th century caricatures of the Irish. In the run up to St Patrick's Day 2014, the Hibernians successfully campaigned to stop major American retailers from selling novelty merchandise that promoted negative Irish stereotypes.
Some have described St Patrick's Day celebrations outside Ireland as displays of "Plastic Paddyness"; where foreigners appropriate and misrepresent Irish culture, claim Irish identity, and enact Irish stereotype.
