Lá Fhéile Pádraig

 Lá Fhéile Pádraig - more commonly known as the Feast of Saint Patrick - is celebrated on 17 March each year. The feast commemorates Saint Patrick (c. 387–461 CE depicted here at right), the best known of the patron saints of Ireland.
Saint Patrick's Day was officially recognized in the early 17th century and has been co-opted as a showcase for that oxymoron known as Irish culture.
The original color associated with Saint Patrick was actually blue but over the centuries this has morphed into the now universally accepted green with green ribbons and shamrocks worn on St Patrick's Day as early as the 17th century. In the US today, celebrations include prominent displays of green, overeating, consumption of alcohol, and numerous parades. See here for more of the Florida Grande celebration.
