V. B. Ketkar proposed 8 November 2585 BCE as the first day of Mahabharata War.
Let’s evaluate this proposal, per the method and steps described here:
(1) Per his proposal, let’s calculate the day Bhishma fell in the battle = 17 November 2585 BCE (10th day of the War)
(2) Since V B Ketkar has not proposed specific day for Bhishma Nirvana (at least it is not available to me since I do not have access to his original work). The day of winter solstice in the year 2585 BCE was that of 9 January, 2584 BCE
(3) Problem for this proposal begins right away! This timeline amount to only 53 or 54 days for Bhishma on the bed of arrows.
(4) Per proposal of V B Ketkar, Bhishma was on the bed of arrows for ONLY 53 or 54 days (17 November 2585 BCE – 9/10 January 2584 BCE).
(5) Please refer to specific numbers and descriptions of Mahabharata text observations here.
Mahabharata references 1, 15 and 17 corrborate proposal of V B Ketkar
Mahabharata references 2,3, 4 do not conflict/contradict proposal of Ketkar. I had to invent this new category to deal with criticism for claims by Mahabharata researchers when they did not take into account specific and relevant obserations of Mahabharata text, which they (these researchers) should have taken into account.
(6) Mahabharata references 5 through 14, 16 & 18 (12 of them) conflict/contradict this claimed timeline by Ketkar.
(7) Versimilitude (Truthlikeness) score (Ketkar) = 3 (corrborated) – 12 (conflicted/contradicted) = – 9
(8) Mahabharata references 6, 13 & 14 (related to Bhishma Nirvana) FALSIFY proposal of V B Ketkar.
(9) AV observation (chapter 6), numerous planetary observations (chapter 7), observations of phases and positions of the moon through 18 days of the War (chapter 8), all of them FALSIFY proposal of V B Ketkar.
