The above writeup is a good introduction into this fantastic holiday, found at the end of the Carnival season. One detail it does neglect, however, is just when exactly Mardi Gras is held.

In the spirit of Noding For The Ages, and in order to facilitate your future planning needs, I've compiled a list of future Mardi Gras dates below. To determine the date of Mardi Gras, you must first determine the date of Easter Sunday. Easter Sunday falls on the first Sunday after the first full moon following the Spring Equinox. It can be anywhere from March 23 to April 25. Mardi Gras, always the day before Ash Wednesday, falls 47 days prior to Easter (40 days of Lent + 7 Sundays). This means Mardi Gras can fall on any Tuesday between February 3 and March 9.

Mid-February Mardi Gras celebrations often inspire Valentine's Day-esque float themes and heart-shaped decorations. Years when Mardi Gras falls in March mean that the weather will generally be a bit warmer, especially at night. Also, knowing which week/weekends to book good hotel rooms (if you're a tourist) well in advance can be useful. If you're a local (to whichever city is under consideration, typically New Orleans, Louisiana, USA, though Rio de Janeiro, Brazil has larger celebrations), you can block off weeks on your calendar when you'll be unable to accomplish much of anything due to the throngs of irritating drunken tourists. Of course, if you're local, you won't need this chart, but that's beside the point.

Regardless, it just seemed that this information was begging for inclusion in The Database. Enjoy.
