Significance of Astronomical data
Astronomical data in Indian history is pivotal for understanding significant timelines and events. The Jagadbhushana employs a cyclic format to compute and tabulate the true longitudes of planets over extensive periods. Additionally, astronomical references in the Mahabharata aid in establishing chronological context, while the Sangam poems provide temporal indicators through celestial observations. These frameworks highlight the intricate relationship between astronomy and historical documentation in ancient India.

The concept of Astronomical data in local and regional sources
Astronomical data is essential for understanding historical timelines and events, as seen in the Jagadbhushana's cyclic format for planet longitudes, its application in the Mahabharata's chronology, and its use in dating Sangam literature through celestial observations.
From: Triveni Journal
(1) Use of astronomical references and calculations to establish timelines and significant events mentioned in the Mahabharata.[1] (2) References within the Sangam poems that suggest temporal indicators for dating the works based on celestial observations.[2]
From: History of Science in South Asia
(1) Astronomical data in the Jagadbhushana is structured according to the so-called cyclic format, a scheme in which true longitudes of the planets are computed and tabulated over large intervals of time.[3]
