Mardi Gras (French for "Fat Tuesday") is the day before Ash Wednesday, and is also called "Shrove Tuesday" or "Pancake Day". It is the final day of Carnival (English:IPA: [kaː(ɹ)nɨvəl] and Romance languages:IPA: [karnaval]). It is a celebration that is held just before the beginning of the Christian liturgical season of Lent. The feast should not be confused with the Swedish Fettisdagen (Fat Tuesday) or the Polish Tłusty Czwartek (which translates to Fat Thursday).
