On September 10, Ganpati will be established in Brahma and Ravi Yoga. Ganeshotsav will start from this day and Ganesh Visarjan will be done on Anant Chaturdashi on 19th September. According to the Puranas, Lord Gajanan was born on the Chaturthi Tithi of Shukla Paksha of Bhadrapada month in the mid-day period.
Which is from 12.20 to 01.20 this time. Therefore scholars have insisted on establishing Ganesha at this time. Along with this, there are 4 auspicious times throughout the day for the installation of idols on Ganesh Chaturthi. According to the Puranas and astrological texts, idol installation is not done after sunset, but on this day, Ganesh installation is considered auspicious in Twilight Muhurta.

The idol in which Ganesha's trunk is on the right is considered as Siddhivinayak form. Whereas Ganesha with trunk on the left is called the destroyer of obstacles. There is a tradition to install Siddhivinayak in the house and the destroyer of obstacles is installed at the gate outside the house. So that any kind of disturbance i.e. troubles can not enter the house. For business establishments, Ganpati ji with the trunk bent towards the left and the right trunk for the house is considered the best.
The celebration of Ganesh Chaturthi assumed a public observance when Maratha ruler Shivaji used it to rouse nationalist sentiments among his subjects who were fighting the Mughals. The festival was revived by Bal Gangadhar Tilak in 1893 when the British had banned political assemblies.
