(NewsNation) — In various cultures around the world, pre-Lenten celebrations bring forth indulgence and festivity. But what sets Fat Thursday, Fat Tuesday, and Mardi Gras apart?

Fat Thursday:
Originating in Poland and Central Europe, Fat Thursday, or “Tłusty Czwartek” in Polish, marks the last Thursday before Lent. It’s a day of feasting on sweets, particularly doughnuts called “pączki” in Polish, to indulge before the fasting period of Lent begins.

Fat Tuesday:
Known as Shrove Tuesday, Carnival Tuesday, or Mardi Gras (French for “Fat Tuesday“), this day falls on the eve of Ash Wednesday, signifying the beginning of Lent in Western Christianity. Across cultures like Brazil’s Carnaval, New Orleans, and parts of Europe, people revel in elaborate festivities and feasting before the solemnity of Lent kicks in.

Mardi Gras:
Mardi Gras gained popularity in America when French explorers arrived in Louisiana in 1699 on Shrove Tuesday. It’s synonymous with Fat Tuesday, representing a day of celebration and indulgence before the Lenten season.

As Christians prepare for the 40-day period of Lent, symbolizing Jesus Christ’s 40-day fast in the desert, these pre-Lenten celebrations offer a final chance to enjoy rich foods and festivities. From Paczki Day in Polish communities to Pancake Day in the UK, each culture adds its own flavor to this pre-Lenten tradition.

So whether you’re munching on paczki, flipping pancakes, or donning Mardi Gras beads, these celebrations lead up to a period of reflection and sacrifice as Lent approaches.
