Vedveer Arya is a distinguished chronologist, historian, Sanskrit scholar and a senior civil servant, whose groundbreaking research has redefi ned the chronology of India and global history. In this two-volume work, he challenges conventional historical timelines, unearthing profound discrepancies that have shaped — and oft en distorted — the perceived origins and chronology of Indo-Eurasian civilizations. Through meticulous research, Arya has exposed pivotal errors in mainstream historiography, revealing a staggering 661-year miscalculation in global chronology and a 1,381-year error in dating the Buddha’s nirvana. His revelations are not mere academic debates; they fundamentally reorient our understanding of the past. Arya’s multidisciplinary approach is as rigorous as it is expansive. Drawing upon epigraphic records, classical literature, and traditional historical texts, he fortifi es his arguments with archaeoastronomical calculations and cross-disciplinary evidence. The result is this two-volume work that not only dismantles inaccuracies entrenched in modern historical discourse but also restores the integrity of traditional world chronology. An accomplished author, Arya has penned seminal works such as The Chronology of India: From Manu to Mahabharata and The Chronology of India: From Mahabharata to Medieval Era (two volumes), which have become essential references for scholars and truth-see kers alike.
