The story of Shri Ram‘s life was first narrated by Maharishi Valmiki in the ‘Ramayan’ which was written after Shri Ram was crowned as the king of Ayodhya, Maharishi Valmiki had a great sense of astronomy as he has made sequential astronomical references on important dates related to the life of Shri Ram indicating the location of planets vis-à-vis the zodiac constellations and other visible stars (nakshatras). Zodiac sign of king Dashratha was Pisces and his nakshatra was Rewati.
He entered the relevant detail about the planetary positions vis-à-vis zodiac constellations narrated by Maharishi Valmiki and obtained very interesting and convincing results, which almost determine the important dates starting from the birth of Shri Ram to the date of his coming back to Ayodhya after 14 years of exile. Pushkar Bhatnagar has given very authentic and convincing details of these dates in his book titled ‘Dating the Era of Lord Ram’ published by Rupa and Co’. Ramayan refers to the solar eclipse at the time of war with Khar-Dushan in later half of 13th year of Shri Ram’s stay in the forests.Sky view reveals lunar eclipse starting from 4.15 pm on 12th September 5076 BC from Colombo (7°N; 80°E) All these sequentially fully tally with the description in Ramayan.Only six of the twelve constellations remain above the horizon at the same time.Software shows a solar eclipse on 3rd April 5076 BC which was the only solar eclipse during the entire year.In Sunder Kaand there is a reference to lunar eclipse when Hanuman spots Sita in Ashok Vatika (5/19/14, 5/29/7, 5/35/87).Valmiki Ramayan contains graphic and poetic details of eight constellations during Hanuman’s return journey from Sri Lanka to Sunaabh Hill in the middle of the sea which apparently took about four and a half hours from AM to 11 AM.
