The simple answer is that it is the Tuesday before Ash Wednesday. If you are Catholic or understand Ash Wednesday then you will know that it is the beginning of Lent when you give up most pleasures and excesses. Mardi Gras (Fat Tuesday) was when you went out and did all your excesses. Hope this helps.
