Diwali, also known as Deepavali, is one of the most significant and widely celebrated festivals in India. Often referred to as the "Festival of Lights," Diwali symbolizes the victory of light over darkness, good over evil, and knowledge over ignorance. This five-day festival is observed by millions of Hindus, Sikhs, Jains, and Buddhists across the world, with each religion adding its unique flavor and traditions to the celebration. The festival's name is derived from the Sanskrit word "Deepavali," meaning a row of lights, which is why the lighting of oil lamps (diyas) and the bursting of fireworks are central to Diwali festivities.
