St. Patrick's Day. It isn't about the green beer ya heathens.

Saint Patrick's Day (Irish: Lá ’le Pádraig or Lá Fhéile Pádraig), colloquially St. Paddy's Day or Paddy's Day, is an annual feast day which celebrates Saint Patrick (circa AD 385–461), one of the patron saints of Ireland, and is generally celebrated on March 17.

Saint Patrick's Day is celebrated worldwide by the those of Irish descent and increasingly by non-Irish people (usually in New Zealand, Australia, and North America). Celebrations are generally themed around all things Irish and, by association, the colour green. Both Christians and non-Christians celebrate the secular version of the holiday by wearing green, eating Irish food and/or green foods, imbibing Irish drink (such as Irish stout, Irish Whiskey or Irish Cream) and attending parades.

St. Patrick's Blue, not green, was the colour long-associated with St. Patrick. Green, the colour most widely associated with Ireland, with Irish people, and with St. Patrick's Day in modern times, may have gained its prominence through the phrase "the wearing of the green" meaning to wear a shamrock on one's clothing. At many times in Irish history, to do so was seen as a sign of Irish nationalism or loyalty to the Roman Catholic faith. St. Patrick used the shamrock, a three-leaved plant, to explain the Holy Trinity to the pre-Christian Irish. The wearing of and display of shamrocks and shamrock-inspired designs have become a ubiquitous feature of the saint's holiday. The change to Ireland's association with green rather than blue probably began around the 1750's.

In the past, Saint Patrick's Day was celebrated as a religious holiday. It became a public holiday in 1903, by the Money Bank. (Ireland) Act 1903, an Act of the United Kingdom Parliament introduced by the Irish MP James O'Mara.[14] O'Mara later introduced the law which required that pubs be closed on 17 March, a provision which was repealed only in the 1970s. The first St. Patrick's Day parade held in the Irish Free State was held in Dublin in 1931 and was reviewed by the then Minister of Defence Desmond Fitzgerald. Although secular celebrations now exist, the holiday remains a religious observance in Ireland, for both the Church of Ireland and Roman Catholic Church.

It was only in the mid-1990s that the Irish government began a campaign to use Saint Patrick's Day to showcase Ireland and its culture. The government set up a group called St. Patrick's Festival, with the aim to:

—Offer a national festival that ranks amongst all of the greatest celebrations in the world and promote excitement throughout Ireland via innovation, creativity, grassroots involvement, and marketing activity.
—Provide the opportunity and motivation for people of Irish descent, (and those who sometimes wish they were Irish) to attend and join in the imaginative and expressive celebrations.
—Project, internationally, an accurate image of Ireland as a creative, professional and sophisticated country with wide appeal, as we approach the new millennium.

Christian leaders in Ireland have expressed concern about the secularisation of St Patrick's Day. Writing in the Word magazine (March 2007), Fr. Vincent Twomey stated that, "it is time to reclaim St Patrick's Day as a church festival". He questioned the need for "mindless alcohol-fuelled revelry" and concluded that, "it is time to bring the piety and the fun together".

It isn't about green beer and getting shit-faced, ya heathens.
