Shrove Tuesay is the term used in Ireland, the United Kingdom, Australia, and Canada to refer to the day after Shrove Monday (or the more old fashioned Collop Monday) and before Ash Wednesday (the liturgical season of Lent begins on Ash Wednesday). In Ireland, the UK, and amongst Anglicans, Lutherans and possibly other Protestant denominations in Canada including Newfoundland, Nova Scotia, Prince Edward Island and New Brunswick, this day is also known as Pancake Day, because it is customary to eat pancakes on this day. In other parts of the world—for example, in historically Catholic and French-speaking parts of the United States and elsewhere—this day is called Mardi Gras. In areas with large Polish-immigrant populations (for example, Chicago) it is known as Tłusty Czwartek (literally: Fat Thursday) and celebrated on the Thursday before Lent. And in areas with large German-immigrant populations (for example, Pennsylvania Dutch Country) it is known as Fasnacht Day (also spelled Fausnacht Day and Fauschnaut Day).
