Festivals are special events that bring people together to celebrate various aspects of culture, religion, or community. They often include music, dancing, food, and colorful decorations. For example, the Diwali festival in India celebrates the victory of light over darkness, while Carnival in Brazil is known for its vibrant parades and lively samba music. These gatherings can be local or global, and they create a sense of joy and unity among participants. Festivals like Oktoberfest in Germany showcase traditional foods and drinks, while Holi, the festival of colors, encourages people to play with colored powders and water, symbolizing love and friendship.
