Valmiki Ramayana contains the history of one of the key events of Indian civilization, viz. The Rama-Ravana Yuddha. The Ramayana consists of nearly 24,000 Shloka, divided into seven Kandas and about 500 Sargas. Valmiki Ramayana has the status of the adi-kavya (first poem).
There are 15+ attempts to date the events of Ramayana. Unfortunately, the majority of these claims are based on either selective evidence or dogmas of AIT/Chatur-Yuga cycles and show characteristics lack of scientific acumen and logical reasoning. This is precisely the reason why researchers have ended up with multiple claims while simultaneously claiming to have employed identical evidence.
What could be the outcome if one can employ all the evidence of the Valmiki Ramayana and test it objectively with the help of science? Is it even possible to accomplish such a thing and arrive at a unified answer?
Nilesh Oak enumerated 575+ specific astronomy and associated observations from Valmiki Ramayana and tested them with the scientific acumen and logical reasoning to arrive at 12209 BCE as the year of the Rama-Ravana Yuddha. The book explores unique astronomy observations from Valmiki Ramayana that decisively falsify all existing claims for the year of the Rama-Ravana Yuddha, and thus the timing of Ramayana.
