Saint Patrick's Day (Irish: Lá Fhéile Pádraig) is a religious holiday celebrated internationally on 17 March. It is named after Saint Patrick (c. AD 387–461), the most commonly recognised of the patron saints of Ireland. It is observed by the Roman Catholic Church, the Anglican Communion (especially the Church of Ireland), the Eastern Orthodox Church and Lutherans. Saint Patrick's Day was made an official feast day in the early 17th century, and has gradually become a celebration of Irish culture in general.
The day is generally characterised by the attendance of church services, wearing of green attire, especially shamrocks, and the lifting of Lenten restrictions on fasting and drinking, which is often proscribed during the rest of the season.
Saint Patrick's Day is a public holiday in the Republic of Ireland, Northern Ireland, Newfoundland and Labrador and in Montserrat. It is also widely celebrated by the Irish diaspora, especially in places such as Great Britain, Canada, the United States, Argentina, Australia, and New Zealand, among others.
