If you ask a local "when does Mardi Gras start in New Orleans," you’re going to get a look. It’s that half-grin, half-confused expression that says you’re asking the right question but definitely from the wrong angle.
Most people think it’s a day. A Tuesday. A single, wild, glitter-covered explosion of beads and bad decisions. Honestly? Fat Tuesday is just the finish line. The actual Carnival season starts way earlier than you think, and if you show up on the wrong date, you’re missing the best part of the soul of the city.
The Magic Date: January 6th
It’s always January 6th.
Rain or shine. Freezing or humid. The Twelfth Night—or the Feast of the Epiphany—is the hard start for Carnival. While the rest of the country is sadly dragging their dry Christmas trees to the curb and wondering where their motivation went, New Orleans is just getting warmed up. This isn't just a calendar date; it's a legal and cultural boundary. In New Orleans, eating a King Cake before January 6th is considered a minor sin, or at the very least, a sign that you aren't from around here.
The Phunny Phorty Phellows, a satirical krewe, literally boards a streetcar on this night to shout at everyone that the season has begun. They wear masks. They have a brass band. They ride the St. Charles line. It’s loud, it’s chaotic, and it’s the official "go" signal.
Why the date shifts every year
So, here is where it gets slightly annoying for people trying to book flights. While the start is always January 6th, the end—Mardi Gras Day itself—wanders around the calendar like a tourist who had one too many Hand Grenades on Bourbon Street.
It’s all tied to Easter.
Mardi Gras must be 47 days before Easter. Since Easter is based on the lunar cycle (the first Sunday after the first full moon of the spring equinox), Fat Tuesday can fall anywhere from February 3rd to March 9th. This creates a "short" season or a "long" season. A short season is frantic. It feels like you're constantly running to a parade. A long season? That’s when the city really settles into the rhythm of revelry.
The Build-Up: It’s Not All About the Big Tuesday
You don't just wake up one day and see 50 floats. It’s a slow burn.

After the January 6th kickoff, things are actually pretty quiet for a few weeks. You'll see purple, green, and gold bunting appearing on houses. You’ll smell cinnamon and sugar in every grocery store thanks to the wall of King Cakes near the entrance. But the massive, street-closing parades don't usually hit the pavement until about two weeks before Fat Tuesday.
The "Local" Window
If you want to experience New Orleans without the claustrophobia of the final weekend, look at the weekend before the main event. This is when Krewes like Krewe du Vieux and Krewedelusion march through the French Quarter and Marigny.
They are small. They are raunchy. They are deeply political.
These aren't the massive fiber-optic floats you see on the news. These are hand-pulled carts and brass bands. Honestly, it’s the most "authentic" version of the season you can find. You can actually walk. You can breathe. You can grab a drink at a bar without waiting forty minutes.
The Big Guns
The real heavy hitters—the "Super Krewes" like Endymion, Bacchus, and Orpheus—dominate the final five days leading up to Tuesday. When people ask when does Mardi Gras start in New Orleans, they are usually subconsciously thinking of this window.
- Endymion (Saturday before Mardi Gras) is a beast. It’s the only parade that doesn't follow the standard Uptown route; it rolls through Mid-City. People stake out their spots on the neutral ground (that's the median, for everyone else) days in advance.
- Bacchus (Sunday) features celebrity royalty and floats so big they look like they shouldn't be able to turn a corner.
- Lundi Gras (Monday) is the "Fat Monday" celebration at the riverfront, where the Kings of Zulu and Rex meet. It’s a huge party, but it’s also the calm before the final storm.
Understanding the "Parade Season"
Let's talk logistics because the city basically stops functioning as a normal municipality during the peak of the season.
If you are trying to get a ride-share on the Friday before Mardi Gras, good luck. The "Box" is a real thing. Because the parades follow specific routes through Uptown and Mid-City, large chunks of the city become inaccessible by car once the floats start moving. If you’re inside the parade route, you’re stuck there until the last float passes and the street sweepers do their thing.
It’s a beautiful trap.

The Zulu and Rex Traditions
Everything culminates on Tuesday. If you aren't on the street by 8:00 AM, you're late. The Zulu Social Aid & Pleasure Club starts early, and their hand-painted coconuts are the most coveted "throw" in the city. If you see someone diving into a gutter for a piece of fruit covered in black glitter, don't be alarmed. That’s just standard operating procedure.
Then comes Rex, the King of Carnival. This is the "grand" parade. It’s stately. It’s traditional. It defines the aesthetic of the holiday. By the time the final truck parades pass through in the afternoon, the city is a carpet of plastic beads and discarded go-cups.
The Secret Season: Courir de Mardi Gras
New Orleans isn't the only place celebrating, though it's the loudest.
If you drive a few hours west into Acadiana—places like Mamou or Eunice—the answer to "when does Mardi Gras start" is the same, but the celebration is unrecognizable. There are no beads. There are no giant floats. Instead, you have the Courir de Mardi Gras.
Men and women dress in traditional "capuchons" (tall pointed hats) and fringe-covered suits. They ride horses from house to house, "begging" for ingredients for a communal gumbo. They have to chase chickens. They drink plenty of beer. It’s a medieval, rural tradition that feels much older and grittier than the urban party in the Crescent City.
Planning Your Arrival
Don't just show up on Tuesday. That’s a rookie mistake.
If you arrive on Tuesday morning, you’ve missed 90% of the party. Most savvy visitors arrive the Thursday or Friday before. This gives you the full cycle: the night parades, the celebrity sightings, the high-school marching bands (which are, frankly, the unsung heroes of Carnival), and the general madness of the French Quarter.
What to Pack (The Reality Check)
Weather in New Orleans during Carnival is a chaotic mess.

- Layers are non-negotiable. It can be 75 degrees at noon and 38 degrees by 8:00 PM.
- Shoes you don't love. You will be walking through "street water." It’s not just water. Between the beer, the soda, and the general grime of a million people on the street, your shoes will be ruined.
- A bag for beads. You think you won't want them. You think you're above it. Then the first float passes, the drums start pounding, and suddenly you’re fighting a grandmother for a string of plastic pearls.
Beyond the Beads: The Economic Reality
It’s easy to look at Mardi Gras as a giant frat party, but for New Orleans, it’s a massive economic engine. According to a study by Tulane University, the festival generates over $1 billion in economic impact for the city.
But it's not all profit.
The city spends millions on police overtime, sanitation, and infrastructure repair. It's a delicate balance. Locals often have a love-hate relationship with the season. We love the culture, the music, and the excuse to wear a wig on a Tuesday morning. We hate the traffic, the broken fences, and the fact that you can't get a grocery delivery for two weeks.
Finding Your Own Start Date
Ultimately, Mardi Gras starts when you decide to lean into the spirit of it. For some, it's the first bite of a Dong Phuong King Cake in mid-January. For others, it's the first time they hear the St. Augustine Marching 100 strike a drumbeat on St. Charles Avenue.
If you are planning your first trip, aim for the "mids." The weekend before Fat Tuesday is the sweet spot of energy versus manageable crowds. Check the parade schedules on sites like Arthur Hardy’s Mardi Gras Guide—that’s the bible for locals. It lists every route, every start time, and every krewe history.
Practical Steps for Your Trip
- Download a tracking app. Use "WDSU Parade Tracker" or "WWL Mardi Gras Tracker." Parades get delayed. They break down. These apps show you exactly where the "head" of the parade is in real-time.
- Book dining reservations months out. If you think you’re walking into Galatoire's or Commander’s Palace on the Friday before Mardi Gras without a reservation, you’re dreaming.
- Pick a side. On the parade route, you're either on the "Sidewalk Side" or the "Neutral Ground Side." This matters when you're trying to meet up with friends. Once the parade starts, crossing the street is nearly impossible.
- Bring cash. Many smaller bars and po-boy shops go "cash only" during the heavy parade days to speed up service.
Mardi Gras is a marathon, not a sprint. Pace yourself, hydrate more than you think you need to, and remember that when the bells of St. Louis Cathedral toll at midnight on Tuesday, the party is over. The police literally ride horses down Bourbon Street to clear the way for the street sweepers, signaling the start of Lent.
The transition from the loudest party on earth to the quiet of Ash Wednesday is one of the most jarring and beautiful things you’ll ever experience. Be ready for it.
