Fat Tuesday is the English translation of Mardi Gras, which is a day of feasting and celebration that precedes the fasting period of Lent in Christian traditions. It is known for indulging in rich, fatty foods before the ritual fasting of the Lenten season begins on Ash Wednesday. It’s also associated with Carnival celebrations, particularly in places like New Orleans, where parades, masquerades, and parties are common. Fat Tuesday occurs on the Tuesday before Ash Wednesday each year.
