1. An annual festival held in France on the day before Ash Wednesday, the first day of Lent. Mardi Gras is French for “Fat Tuesday” — meaning it is the last opportunity to eat rich food before the fast of Lent begins. It is related to celebrations elsewhere, called “carnivals,” from the Latin words carne and vale, “meat” and “farewell,” meaning a farewell to meat before the abstinence of Lent.

Usage

What is Mardi Gras? Mardi Gras is the last day before Lent—the Tuesday before Ash Wednesday. It is sometimes called Fat Tuesday, which is what its name means in French. The term Mardi Gras also refers to the festival that takes place on this day and in the days (or even weeks) leading up to it. This festival is especially associated with the U. S. city of New Orleans, where it is prominently celebrated. In other places, this festival is called Carnival. Lent is the season of fasting and penitence that precedes Easter in some branches of Christianity. Mardi Gras is part of a tradition of indulging before the Lenten fast, but it is not a Christian holiday.
