St. Patrick's Day is a celebration. It is on March 17th. It is a very important day for people in Ireland.
The history of St. Patrick is very interesting. St. Patrick was a priest. He helped Irish people. Irish people love St Patrick.
On St. Patrick's Day, people usually wear green clothes. Green is the national colour of Ireland. Also, green is the colour of the shamrock. The shamrock is a plant with three leaves. It is the national symbol of Ireland. St. Patrick's Day is fantastic.
