Saint Patrick's Day is a holiday celebrated internationally on March 17th. It is named after Saint Patrick, the most commonly recognized of the patron saints of Ireland. This is a traditional day for spiritual renewal and offering prayers for missionaries worldwide. It has gradually become more of a secular celebration of Irish culture. Saint Patrick's Day is a public holiday in the Republic of Ireland, Northern Ireland and Newfoundland.

The traditional symbols of St. Patrick's Day are shamrocks, leprechauns and corned beef and cabbage.

Originally, the color associated with Saint Patrick was blue. Over the years, the color green and its association with Saint Patrick's Day grew. If one doesn't wear green, they will get pinched. Green ribbons and shamrocks were worn in celebration of St. Patrick's Day as early as the 17th century. The most common traditions on St. Patrick's Day include wearing green, enjoying Irish folk music and food, and by consuming large quantities of Irish beer (as they are often dyed green), such as Murphys, Smithwicks, Harp or Guinness or other Irish liquors such as Irish whiskey, Irish coffee or Bailey's Irish Cream.
