What is St Patrick's Day?

St Patrick's Day celebrates the life of a bishop from the fourth century, who then became the Patron Saint of Irish. The day is celebrated on 17 March as this marks the death of the saint in 461. The day began as a feast day to mark St Patrick's Day in the 17th century and then became a national holiday in the Republic of Ireland in 1903.

St Patrick's Day is celebrated across the Republic of Ireland and the rest of the world by wearing the symbolic colour of the day, green, eating traditional Irish food and drinking Irish stout. The Irish symbol of the shamrock is often also worn on the day.
