It is dedicated to various forms of Goddess Durga. Golu is a dolls festival celebrated during Navratri. Apart from Tamil Nadu, it is also a part of the festivities in Andhra Pradesh and Karnataka. In Tamil Nadu it is called as Bommai Golu and in Telugu it is known as Bommana Koluvu.
Usually last set of 3 days would be fine as you can celebrate Saraswathi pooja along with golu setup 🙂 My MIL has the practice of keeping Golu/Kolu in salem home every year on all the nine days. … Golu can be kept either in a grand manner with 9 or 11 steps OR just in a simple form with 3 steps.
On the Amavasya day, Golu steps are to be set preferably facing the east direction. We can also keep the steps facing west or north, but never facing south. The Golu dolls are kept on steps called the Golu Padi which are set up using wooden planks or steel steps.
Sharada Navaratri: the most celebrated of the four Navaratri, named after sharada which means autumn. It is observed the lunar month of Ashvin (post-monsoon, September–October).
Golu is the festive display of dolls and figurines in South India during the autumn festive season, particularly around the multiday Navaratri (Dussehra, Dasara) festival of Hinduism. These displays are typically thematic, narrating a legend from a Hindu text or a secular cultural issue.
