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. 385 – c. 461), the foremost patron saint of Ireland.
St. Patrick’s Day is celebrated annually on March 17, the anniversary of his death in the fifth century. The Irish have observed this day as a religious holiday for over 1,000 years. On St. Patrick’s Day, which falls during the Christian season of Lent, Irish families would traditionally attend church in the morning and celebrate in the afternoon. Lenten prohibitions against the consumption of meat were waived and people would dance, drink and feast–on the traditional meal of Irish bacon and cabbage.
