Vinayaka Chavithi, also known as Ganesh Chaturthi, is a Hindu festival dedicated to Lord Ganesha, the elephant-headed god of wisdom and prosperity. It typically involves installing an idol of Ganesha in homes or public places, offering prayers, performing rituals, and enjoying festive foods. The celebrations can last for several days, culminating in the immersion of the idol in water, symbolizing the return of Ganesha to his divine abode.
