According to the 3139BCE timeline, Balarama’s pilgrimage which must start on Pushya and after the Amavasya mentioned in Udyoga140:18 which should be at Jyestha but is instead at Chitra….. allows the pilgrimage to start on Sept 22nd 3139BCE. (Pushya star)
This needs to end 42 days later on November 2 3139BCE on Shravana star (which is fine) BUT it must be noted that the day needs to coincide with a Moon phase approaching or at Amavasya which is the 18th day of the war.
Fixing 18th day of war in 3139BCE:
Guess which Moon phase Balarama arrives back from his pilgrimage on in 3139BCE? It’s Shukla paksha Chaturthi. Thus Balarama arrives a full 6 days after Gada Yuddha assuming a Shukla Ekadashi start to the war or 4/5 days later after the Gada Yuddha, if one assumes a near Amavasya end to the war (and 6 days after the 18th day of the war ended in 3139BCE.)
Thus Balarama misses the Gada Yuddha in 3139BCE completely. This is one of the major failings of the traditional date of the war.
