Ganesha Chaturthi is the Hindu festival celebrated on the birthday (rebirth) of Lord Ganesha, the son of Shiva and Parvati.
It is believed that Lord Ganesh bestows his presence on earth for all his devotees during this festival. It is the day Shiva declared his son Ganesha as superior to all the gods, barring Vishnu, Lakshmi, Shiva and Parvati. Ganesha is widely worshipped as the god of wisdom, prosperity and good fortune and traditionally invoked at the beginning of any new venture or at the start of travel. The festival, also known as GANESHOTSAV ("festival of Ganesha") is observed in the Hindu calendar month of Bhaadrapada, starting on the shukla chaturthi (fourth day of the waxing moon period). The festival lasts for 10 days, ending on Anant Chaturdashi (fourteenth day of the waxing moon period).
