Jain councils

The later texts states that the last Vallabhi council was held 980 or 993 years after the death (Nirvana) of last Tirthankara Mahavira (After Vardhamana = AV).

The Avashyaka-churni (dated between Samvat 650 and 750=593–693 CE) describes: There was twelve years long famine which resulted in the monks moving to the coast.

"[1] Hemchandra's Parishishtaparvan, probably based on Avashyaka-churni; also known as Sthaviravali (stories on the lives of elders or Jain patriarchs), contains detailed information about the council and how the knowledge of the Purvas was lost.

[1] Nandisutra by Devavachaka mentions Skandila and Nagarjuna in Sthaviravali (list of elders) who had organised the sacred texts.

[1] Bhadresvara's (c. 1150–1200 CE) Kahavali is not considered as reliable source for date though it contains tales mentioned in earlier literature.

Jinaprabhamuni's (1307 CE) Sandehavisausadhi, commentary on Kalpasutra, was the first indication of associating 980 AV with Vallabhi Council but also cite other possibilities.
