The Epic-Puranic chronology is a timeline of Hindu mythology based on the Itihasa (the Sanskrit Epics, that is, the Mahabharata and the Ramayana) and the Puranas. These texts have an authoritative status in Indian tradition, and narrate cosmogeny, royal genealogies, myths and legendary events. The central dates here are the Bharata War and the start of the Kali Yuga.
These texts often discuss very long lengths of time, such as the widespread statement that Vaivasvata Manu lived 28 yuga cycles before the writer's time, which, if the usual yuga cycle of 4,320,000 years is meant, is 120 million years.
