When Is Mardi Gras 2025 Day. When is mardi gras going to be held in 2025? Next year’s carnival season will last 20 days longer than in 2024, with a total of 58 days between 12th night and fat tuesday

Unlike christmas or the 4th of july which always fall on the same calendar day, the only thing you can count on for sure with carnival is that fat tuesday will fall on, well, a tuesday. Parades will begin in many locations in january.
