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. (Or in this case, by trying to catch up still on homework and work work.)
