Mardi Gras is almost over.

Beginning as a religious holiday observed prior to the Christian Lenten season, Mardi Gras has since expanded from a single day of observation to weeks (or months) of partying.

The festivals and celebrations in the weeks leading up to the Lenten season are celebrated across the world, from France to Brazil and beyond. And, in the U.S. although it is celebrated in other cities like Mobile, Alabama, St. Louis, Missouri, Galveston, Texas and cities throughout Louisiana, it’s most famously celebrated in New Orleans, Louisiana.

New Orleans takes Mardi Gras seriously, with traditions including king cake and parades beginning in January and lasting for weeks until the actual holiday itself.

Here’s everything to know.

When is Mardi Gras 2025?

This year, Mardi Gras, which translates from French to “Fat Tuesday,” is on March 4.

Ash Wednesday is on March 5, the day marking the start of the 40-day Lenten season that culminates with Easter.

Why does New Orleans celebrate Mardi Gras?

Although it is a Christian holiday now, Mardi Gras is a holiday that dates back thousands of years to pagan spring and fertility rites, according to the History Channel. Mardi Gras, also often called Carnival or Carnaval, is celebrated in countries around the world with large Roman Catholic populations.

Louisiana was colonized first by the French before it became part of the U.S., and has retained strong French and Cajun culture and traditions, including Mardi Gras.
