There are various versions of the life story of St. Patrick but for the most part, it is agreed that having being kidnapped from Wales, a young Patrick worked as a slave tending pigs in Co. Antrim until finally escaping and returning home after several years of intense hardship. 

Having returned home, however, he was called back in a dream to save Ireland and convert the Irish people to Christianity, subsequently making it his life's mission to deter the native tribes from their pagan ways.

The feast day was penciled into the universal liturgical calendar in the Catholic Church in the early 17th century thanks to the influence of Waterford-born Franciscan scholar Luke Wadding.

When St. Patrick’s Day falls on a Friday during Lent, the obligation to abstain from eating meat does not have to be adhered to.

When March 17 falls during Holy Week, the actual celebration date can be moved. In 1940, St. Patrick's Day was observed on April 3 in order to avoid clashing with Palm Sunday, and again in 2008, when it was observed on March 15. St. Patrick's Day will not fall within Holy Week again until 2160 – when it will fall on the Monday before Easter.

Everyone dons green and gold and wears a shamrock on some part of their body to symbolize their Irishness on March 17, showing the world that they're Irish.

This is just one small part of the many, many traditions that have spread throughout the world through the decades. Some more of them can be found here

However, there are certain traditions undertaken around the world that the Irish can not claim attachment, too, especially that horrible American habit of incorrectly saying St. Patty's Day or their love of drinking ridiculous green beer.

Religious people go to mass on St. Patrick’s Day to pray to God and thank him for their patron saint. It is a traditional day for spiritual renewal and offering prayers for missionaries worldwide even though St. Patrick was never officially canonized as a saint by the Catholic Church. 

As a result, up until very recently in Ireland, there was no means by which you could enter a pub or buy yourself a pint of Guinness. You can read the full story of the tradition here.
