Mardi Gras ends up falling between Feb. 3rd and Mar. 9th. But the official carnival celebration starts Jan. 6th. It ends on midnight the day before Ash Wednesday, also known as "fat tuesday". They made this a holiday because they want everyone to get the partying out of their system before the holiday and choice of lent. Beads are thrown to people with the best costumes and outrageous behavior, the more beads you were receiving means that's the crazier you are. You must also wear the colors purple green and gold, it stands for justice faith and power. Though New Orleans is well known for this festival, many places all over the world celebrate it all the same. Some people have crazier parties, while some just like being gathered as a group.
