Chronology Markers and History of Indian Heritage: Chronology Markers Project

India is a storehouse of rich heritage. The architectural sites, scientific researches, literary observations, spiritual traditions,cultural practices, and much more, aspropoundedby visionary Indian seers. The unique and the enriched heritage of India have always attracted seekers of ancient Indian wisdom. By chronology marker, we mean dating of events using internal references to astronomical calendars traditionally provided with the texts of India, both ancient and modern by cross verification. 

The Project

The aim of this project is to formulate a chronological context of ancient Indian knowledge and verify them with the traditional assumptions.Starting with the oldest literature we have, i.e., ?gVeda upto the Epics and Puranic literature, the comparative analysis of the texts is part of this comprehensive study.Approach of this project sometimes may lead to interdisciplinary studies such as ayurveda, astronomy, history, geology,etc. For example – if we want to know the origin, development and modification about "Dev-Pitru-Uttara-DakshinAyan", we need to explore all relevant aspects like astronomical, social, and astrological information. This vast study includes various observations on seasons, lokas, time-cycles, constellations, planetary movements, months, polestar, etc. Taking up this project is relevant in modern era, as it gives us opportunity to explore centuries old available texts. 
Initial efforts are being made to date Indian epics, Ramayana and Mahabharata. Current findings based on textual interpretation and astronomical computations are challenging many previous held wrong notions of the history of Indian culture and traditions. It is expected that comprehensive scholarship in such studies will open doors to consider several fundamental issues about the origin and utility of Indian values and knowledge system.
