Sankashti Chaturthi is the 4th day of the waning lunar phase after the full moon.

This is the fourth day of the second fortnight of the Hindu Calendar Month. On this day a special significance is to the sighting of the Moon.

The pujas, from Sunrise, are as per Tuesday but in the evening the temple closes about 1 1/2 hour prior to moon rise and Shodashopchar Pooja is performed on Shree Siddhivinayak and an Abhishek of Milk and Rose Water on Shree Siddhivinayak goes on while a team of priests recite various Vedic Mantras and Prayers.

A Naivedya comprising of Steamed Modaks and other eatables is then offered to Shree Siddhivinayak and following the same is the Aarti Mantra Pushpanjali. After this the temple is again open to devotees and Shejaarti is performed only after the crowd subsides. The benefits of Chaturthi fasting include material progress, happiness and fulfillment of desires. The importance of Chaturthi vrat was explained by Lord Krishna to Yudhishtira, the eldest of the Pandavas. It is also mentioned in the Narasimha Purana and Bhavishaya Purana.
