Ganesh Chaturthi, a Hindu festival that celebrates the birth of Lord Ganesha, is observed for 10 days. This is because of the story behind the festival, where it is believed that Ganesha wrote the Mahabharata continuously for 10 days and had to bathe in the Saraswati River to clean the dust and grime accumulated on his body. Another belief is that Ganesha travels on Earth during these 10 days, giving his devotees a chance to welcome him into their homes. The final day, Anant Chaturdashi, symbolizes the immersion of Ganesha's idol, where devotees bid farewell, seeking his blessings for his return next year.
