According to the Panchang, the Chaturthi tithi for Ganesh Chaturthi 2026 will begin at 7:06 AM. Meanwhile, the auspicious muhurat for Ganpati sthapana in New Delhi has been given as 11:02 AM. This means there is a gap of roughly four hours between the start of the tithi and the auspicious installation time. The source material notes that this period is typically used to prepare the idol and puja materials, though the exact set of activities devotees should undertake during this window is not detailed in the available information. Devotees commonly use such time for bathing, cleaning, decorating the puja area, and preparing for the idol installation, but this is not explicitly stated in the source and should not be presented as confirmed fact.
