Part II, Chapter 1 begins in February.
The last week of Carnival before Mardi Gras; business is very slow.
Having originated in European countries which were predominately Catholic and later celebrated in the European colonies, the Carnival (known as King's Day) begins on January 6, the Feast of the Epiphany and the twelfth day of the Christmas season, ending with Mardi Gras (Shrove Tuesday), which then commences the six weeks before Easter with Ash Wednesday, marking the beginning of the Lenten period before Easter. Since Easter Sunday does not come on the same Sunday of the year, the exact day cannot be made certain. With Easter falling anywhere between March 23 and April 25, Mardi Gras takes place 47 days before Easter. If Easter is as late as April 25, then Mardi Gras will fall in very early March. However, it is in February most of the time, around the second or third week. Mardi Gras originated in European countries which were Catholic countries.
Much of the strength of Walker Percy's narrative lies in the connotations of setting. With the mention of Mardi Gras, there is, then, the evocation of the watcher of parades, the non-participant that Binx Bolling is as the "moviegoer" who finds viewing life as comparable to motion pictures.
