Chadurthi is a day of importance for Lord Vinayaga, and is considered auspicious to initiate any new endeavor, job or project. This occurs twice every month once during the growing moon period and once during the waning moon period. The Chadurthi, which falls during the growing moon period, is known as Sangadahara Chadurthi and is considered more auspicious than the other. The main Chadurthi called Sri Vinayaga Chadurthi occurs during the month of September in the growing moon period and is celebrated with pomp and splendor in Bombay, Madras, Pune, Calcutta and other parts of India. During this festival large decorated idols of Sri Vinayaga are drowned in the rivers and lakes to mark the occasion.
