Mardi Gras, also known as Fat Tuesday, is a festive celebration that takes place annually in many countries around the world. It is particularly popular in areas with strong French or Catholic influences, such as New Orleans. The event is usually held on the day before Ash Wednesday, which marks the beginning of the Christian season of Lent. Mardi Gras is known for its vibrant parades, colorful costumes, lively music, and exuberant street parties. Participants often wear masks and elaborate outfits, and they throw strings of beads, coins, and other trinkets to the cheering crowds.
