I was always confused as to why they say that Bheeshma Ekadas is the birth of VishnuSaharanamam. as we know Bheeshma died on Ashtami day so how could he give the Upadesh of Vishnu Sahasrnamam on Ekadasi day which succceeds ashtami ...Some scholars say that Bheeshma Ekadas thithi is celebrated as a mark of respect to the noble soul.
We all know that Uttarayana is Makar Sankranti which falls near to January 15 while Bhishma Ashtami falls during February i.e. Bhishma Ashtami always falls after Makar Sankranti. So how it is possible to have such a chronology? We cannot dispute the day and the chronology as Hindus are observing the day of Bhishma Ashtami since ages and this information is getting passed through generation to generation without any likelihood of mistake. Hindus, being the oldest civilization which has roots so deep in the past that even modern science deny to believe, might not maintain the year when Bhishma Pitamah died but cannot forget the Tithi when he died as Hindus are doing Ekodishta Shraddha for him generation after generation.
It is widely believed that 5114 years have passed since Kali Yuga has started and this counting is well maintained by Hindu Panchang makers. It is also accepted that Kali Yuga started with the Death of Lord Krishna. The time when Lord Krishna left the Earth for Vaikunta He was 126 years old and during the time of Mahabharata He is believed to be 90 years old. Hence it was approximately 5151 years before when Bhishma Pitamah was died.
At the time of Mahabharata the Gregorian calendar which is popularly known as English calendar was not available. But to understand the chronology of Bhishma Pitamah death anniversary we can assume that Gregorian calendar was available during the time of Mahabharata. The Gregorian calendar has been designed such that it is aligned with seasons. Hence all seasonal events fall on the same day with in the difference of one day. In other words the day of Winter Solstice on Gregorian calendar is almost fixed either on December 21 or December 22. As the day of Winter Solstice is fixed it would have been the case during the Mahabharata era. Hence we can say that it would have been December 21 or December 22 when Bhishma Pitamah chose to leave his body. Now to verify the chronology under discussion we have to go back approximately 5151 years back and we have to find Hindu Tithi and month prevailing during the month of November or December on assumed Gregorian calendar, also known as Proleptic Gregorian Calendar.
To understand our work one has to understand that Hindu Lunar months are not fixed on Gregorian calendar. Hindu months (including Sankranti dates) are moving away from Winter Solstice. Today Magha Ashtami falls during the month of February but after couple of thousand years it would shift to March, then April and so on. This shifting of Hindu dates on Gregorian calendar is valid for Sankranti dates also. One can check that on Gregorian calendar during year 1600, Makar Sankranti occurred on January 9 and by the year 2600, Makar Sankranti would shift to January 23. Hence Sankranti along with Magha month is drifting away from Winter Solstice.
When we ran Drik Panchang Software and converted the Gregorian date at the time of Mahabharata period we found that it was the month Magha which was prevailing before Winter Solstice.
Gregorian year during Mahabharata = -3227 + 90 = -3137
Makar Sankranti date in Gregorian year -3137 = November 2
Magha Shukla Ashtami date in Gregorian year -3137 = November 28
From the above dates we can conclude that there is no doubt that it was Winter Solstice which was auspicious day of Uttarayana as no other theory would explain the chronology of death anniversary of Bhishma Pitamah. However this paper is not able to confirm that it was 5151 years before when Pitamah was died as we found slightly wider gap between Magha month and Winter Solstice. Magha Shukla Ashtami was getting over approximately 20 days ahead of Winter Solstice in the assumed year of the death of Bhishma Pitamah.
It is important to mention that Drik Panchang doesn't question the timing of the day of Makar Sankranti. Makar Sankranti which is marked based on Sidereal Zodiacs is appropriate and as per Vedic rules. The day of Makar Sankranti should not be confused or mixed with Winter Solstice. We don't support any view that proposes "Winter Solstice should be celebrated as Makar Sankranti". This paper has tried to clarify that at the time of Mahabharata, Hindus were observing two separate religious events known as Sankranti and Uttarayana. If it were not the case "Bhishma Ashtami is observed on Magha Shukla Ashtami and it was the first day of Uttarayana which Bhishma Pitamaha chose to leave his body" would not make any sense.

![- Bheeshma Sthuthi ~ Lyrics with meanings and Audio ~ Rendered by Mukkur Sri Lakshminarasimhachariar - https://www.youtube.com/watch?v=cNMk7SsacQoThis sthuti is sung by Bheeshma. Here are the verses before this sthuti from Srimad Bhagwatham:Sta said: "Yudhishthhira, who heard that from him who was lying on a bed of arrows, asked him, with the rishis listening, about the diverse religious duties. Bhshma described to him the different stages of life and the vocations as determined by the qualities of the person next to the way how one should deal systematically with both the symptoms of attachment and detachment. He explained about the duties of charity, ruler ship and liberation by giving their divisions and gave the general outline of the duties of women and devotional service. Knowing the truth he described, o sages, the [four basic civil virtues of] religious dutifulness, economy, fulfillment of desires and liberation, to which he cited various known histories. During the time Bhshma described the duties, the sun ran over the northern hemisphere, which is precisely the desired time preferred by the mystics when they want to leave this world. Bhshmadeva, the protector of thousands of sciences and arts, then fell silent and with a mind freed from all bondage he fixed his eyes wide open upon the Original Person Lord Sr Krishna, the Four handed One who was standing before him in yellow garments. Simply looking at Him, the Annihilator of the Inauspicious, his meditation purified and his pain from the arrows disappeared instantly. And while he prayed before the material tabernacle all the activities of his senses ceased when he departed for the Controller of All Living Beings. - - Let me being freed from desires prepare my mind for the Supreme Lord, the Leader of the Devotees, the Great Self-contented One who in the realization of His transcendental joy at times [as an avtara] takes pleasure in accepting this material world with her creation and destruction. - He is the most desirable person of the higher, lower and middle worlds. Bluish like a tamla tree, He wears His dress that shines like the golden rays of the sun. He has a body decorated with sandalwood pulp and a face like a lotus. May my love free from material motives repose in the friend of Arjuna. Let the mind be directed towards Sr Krishna who, with His scattered hair that on the battlefield turned ashen from the dust of the hoofs, with His face decorated with perspiration and His skin pierced by my sharp arrows, wearing His protective armor took pleasure in all of it. - - After hearing the command of His friend He drove His chariot between the opposing forces, where positioned He diminished the lifespan of the enemy by simply looking at them. Let there be my love for that friend of Arjuna. - - While the troops were looking at a distance, He with His transcendental knowledge eradicated the ignorance of him who, because of a polluted intelligence, was reluctant to kill his kinsmen. Let there be the transcendence of my attraction for His feet. For the sake of the fulfillment of my duty factually to be more of violence and against His own sworn principle [to stay out of the fray], He got down from His chariot, took up it's wheel and - while dropping His outer garment - paced towards me like a lion that is about to kill an elephant.- Wounded by the sharp arrows and without His shield He, smeared with blood, in the angry mood of the great aggressor moved towards me in order to kill me. May that Supreme Lord who awards salvation become my destination. Let me, at this hour of death, be of love for the Personality of Godhead who, controlling the horses with a whip in His right hand and the reins in the left, so elegant to behold by all means protected the chariot of Arjuna. It was by looking at Him that those who died at this place realized their original form. Watching the attractive movements of His supremely spirited, fascinating acts and sweet smiles, the gops of Vrajadhma [the village of Krishna's youth] imitating Him in ecstasy, found their original nature. When King Yudhishthira performed the Rjasya royal sacrifice where the great sages and kings were assembled, He received the respectful worship of all the members of the elite. I present there recognized Him at the time [and still remember Him now] als the spirit soul, as the object of worship. Having experienced the absorption of being freed from the misconceptions of duality, I know [ever since] that He, now present before me, is the One Unborn in the heart of the conditioned soul. It is He who in His being situated as the Super soul in the heart of all who are created by Him, just like the one sun, is looked upon different from every angle.Note: These verses are from Srimad Bhagavatam, First Canto, and Ninth chapter verses 32 -42](https://scontent-a-ord.xx.fbcdn.net/hphotos-ash3/t1/s403x403/1794538_701954483168671_871089056_n.jpg)
