Now we will examine the dates given by Shri. Achar for some main events prior to the war and thereafter.
1.Krishna’s departure from Upaplavya. – The date given is Sept. 26. In the year 3067 BCE the winter solstice came on Jan 13, 3066 BCE. The Autumal Equinox was 90 days earlier or on Oct 13 +/- a day. The text clearly says that Krishna left ‘शरदान्ते हिमागमे’ So the departure date should be on or after Oct 13. The date shown by Shri. Achar is about 17 days earlier or well before end of Sharad Ritu.
2.The entire visit of Krishna ending with his dialogue with Karna has been shown before Autumnal Equinox and no justification for that has been provided. This is not consistent with the text.
3.After the solar eclipse on Oct. 14, still before Autumnal Equinox, the start of war is shown on Nov. 22 and moon is mentioned to be at Bharani. What is the explanation for the one month and 8 days in between? Even if we take it that the seven days mentioned by Krishna for start of war, which ended on the day of the solar eclipse or Oct. 14, were for starting war rituals, did the rituals go on for a month and 8 days? There is no description of any such war rituals carried out by either side in the Mahabharata Text.
4.What was the tithi on the first day of the war? Only mention in Mahabharata is what Krishna said to Karna ‘Let us begin the war after 7 days on Amavasya.’ On 22nd Nov. the tithi would be Shukla Saptami or Ashtami Why this tithi has been selected as first day is not explained. There is no mention of this tithi in the Text. There is no mention of the war beginning on Bharani day either.
5.14th day of war is shown as Dec. 8. From Nov. 22nd as first day, 14th day would be Dec. 5 and not Dec 8!
6.Same discrepancy is seen in 18th day- Balarama returning. From 22nd Nov, 18th day would be 9th Dec. and not 12th Dec.
7.The day of Bhishma’s death is shown as Jan 17. If war began on 22nd Nov,. 10th day would be 1st Dec. From then his death would be only after 47 days. Bhishma himself clearly said that he spent 58 painful nights on the deathbed. There is a big mismatch here.
8.When Dec.8 is not the 14th day and Dec. 12th Dec. is not the 18th day, the star maps of these two days have no relevance. On 9th Dec, the actual 18th day, moon would not have been in Shravan.
9. I presume Shri. Achar is aware of the timespan identified by Shri. Oak, during which Arundhati was ahead of Vasishtha as mentioned by Vyasa. The year of war examined by Shri. Achar is well outside that time span and in fact Arundhati was Maximum Behind vasistha in that year. One would expect Shri. Achar to disprove the findings of Shri. Oak or to clarify why he does not find it necessary to accept the limits stated by Shri. Oak. He has done neither.
We can see that the time line proposed by Shri. Achar violates two facts very clearly stated in the text itself, viz., A)Krishna started from Upaplavya after the end of Sharad Ritu which is further borne out by his description of dry ground, plenty of grass etc. at kurukshetra, when he invited the Kouravas to begin war in 7 days (Vyasa’s description matches) and B)Bhishma spent 58 painful nights on the deathbed, as he himself clearly stated just before dying on Winter Solstice. As an ordinary reader of Mahabharat I would expect the Researchers not to distort these main elements of the story, to suit the so-called astronomical observations. Based on Bhishma expiring after 57 days (58 nights) on deathbed and that he fought for first 10 days of the war, the start of the war has to be 66-67 days before the winter solstice. This makes it about 23-24 days after Autumnal equinox. This period is enough for Krishna Shishtai and both sides reaching Kurukshetra. This is a natural time for start of war and matches with what Krishna and Vyasa have said. The whole story of the war is between Autumnal Equinox and Winter Solstice.
For any year in the distant past the researcher may examine, the dates of Winter Solstice and Autumnal Equinox get automatically fixed. This fixes the date of start of war and other consecutive days up to eighteenth day. These will be binding dates for that year and the researcher has to work as per that time-line to verify, by planetary software or by any other means, which astronomical statements by Karna or Vyasa or anyone else validate and which do not. I do not see how any researcher can outstep these limits.
Regrettably, both Shri. Oak and Shri. Achar have twisted the main story which is not acceptable to me as a reader of Mahabharata.
