There is no Biblical significance to the day before Lent begins. The 40 days of Lent represent the 40 days Our Lord spent in the desert fasting and praying before he began his public life. It should be a time of fasting and praying for us, also. The day before, 'Mardi Gras,' is sometimes considered a day to go to excess on food and alcohol before the penance of Lent begins.
The day before Easter is simply Easter Saturday. The day before that is Good Friday.

Shrove Tuesday is the last Tuesday before Lent and the day before Ash Wednesday Mardi Gras is also known as Fat Tuesday or Shrove Tuesday. It is the last day of feasting before Lent begins on Ash Wednesday. Eggs and milk were at one time forbidden on Lent and therefore and had to be used up before Ash Wednesday, so on the Monday before lent , eggs were eaten, or gifts of pancakes, flour, eggs were handed out to prepare final meals on Tuesday. This is why Shrove Tuesday is known as Pancake Day in England.
It ends the same day as the Roman Catholic lent- the day before Easter. But it starts the Monday before Ash Wednesday. And the requirements are much different.
