Carnival(狂欢节) does not take place only in Louisiana. There are many celebrations around the world.

In Brazil, the celebration is supposed to go on from the Saturday before Mardi Gras (大斋节前的最后一天)to Mardi Gras Day, but in some Brazilian cities the celebration can last seven or eight days. Just like New Orleans, not many important things are decided in Brazil from New Year's Day to Mardi Gras Day because everyone is preparing for or celebrating carnival. Most Brazilian parades have a subject, which could be political or historical. The parades had to have a subject related to Brazil until 1996. Some cities in Brazil do not have a street carnival, but they might have an indoor party.

Bolivia has carnival parades for children and then more parades for adults. The children dress up in costumes and march in the streets. The adults make traditional dance groups and dance in the streets. But the main part of Bolivia's carnival is getting wet. Almost everyone gets wet from water balloons and water buckets. In Oruru, Bolivia, their carnival is held in the last ten days of the carnival season. People there join in dancing, but their main carnival event is a ceremonial parade that lasts for twenty hours and parades for four kilometers. Over 20,000 dancers are involved as well as 10,000 musicians. This parade attracts at least 400,000 people.

The carnival in Venice, Italy is often regarded as the most carefully prepared carnival and lasts ten days before Lent (大斋节). Many events are held in the canals including shows, concerts, dances and water processions(队列). The official ending to the celebration is the party held in St. Mark's Square.
