As far as I know, they themselves don't mention this. Which scripture actually has this reference?
1 Answer
Mahabharata 1.2
antare chaiva samprApte kalidvAparayorabhUt | samantapa~nchake yuddhaM kurupANDavasenayoH || 9||
It was at this same Samantapañcaka that at the juncture of the dvApara yuga and the kali yuga the war between the armies of the Kurus and the Pāndavas was fought.
