What is Fat Tuesday?

Fat Tuesday, also known as Mardi Gras is an unofficial celebration that is generally recognized by those of the Catholic denomination of Christianity, or by any other group that fasts for Lent during that same time (this would exclude the Eastern and Oriental Orthodox denominations, for example, who do not generally celebrate Lent at the same time).

It is celebrated on the day before Lent , the Tuesday before Ash Wednesday. It is a day where people eat gluttonous amounts of rich fatty food, drink and 'partake in sin-like behaviors'... Hence the name "Fat Tuesday." it is a time to fast/give up your desires and recognize the Feast of Resurrection.

The Feast of Resurrection, commonly known as Easter, is on a Sunday each year, and the fast of Lent lasts 40 days, according to Catholicism. Therefore, Lent always begins on a Wednesday followed by Fat Tuesday as an annual celebration.
