每年3月17日圣帕特里克節，是愛爾蘭的國慶節。它是為了紀念一位在5世紀時將基督教傳入愛爾蘭的圣人——圣帕特里克。傳說，是他將蛇趕出了愛爾蘭，也是他使遍地生長的“三葉草”成為這個國家的象征。

Saint Patrick"s Day is a public holiday in the Republic of Ireland， Northern Ireland， Newfoundland and Labradｏｒand in Montserrat。 It is also widely celebrated by the Irish diaspora， especially in places such as Great Britain， Canada， the United States， Argentina， Australia， and New Zealand， among others。 Today， St。 Patrick"s Day is probably the most widely celebrated saint"s day in the world。
