New Light on the Epoch of the Kalacuri Era
Summary
New scholarship on the Kalacuri era re‑examines the start date of this important chronological system. Dr. Kielhorn originally placed the epoch at A.D. 248, later adjusting to 247–48 based on North‑Indian inscriptions. The present article surveys early inscriptions from Gujarat and Maharashtra, which align with the 248–49 epoch, and compares them with later epigraphs from North India that fit 247–48. This duality suggests two co‑existing bases. The discovery of Nagardhan copper plates provides a date that combines a particular lunar month, solar eclipse and cyclic year. Astronomical analysis of this combination points to 250–51 A.D., implying a third possible epoch for the Kalacuri era. The author argues that different regions may have used distinct starting points, with the 248 and 247 epochs reflecting local traditions, while the new 250‑51 evidence indicates that a momentous solar eclipse could have been commemorated as the beginning of a third epoch. By comparing epigraphic, astronomical and historical data, the article concludes that the Kalacuri era was more fluid than previously assumed, and multiple starting points may have been recognised at different times and places.

Conclusion
Through epigraphic and astronomical analysis, this article challenges the assumption of a single Kalacuri epoch. It shows that early and later inscriptions correspond to different starting years and uses newly discovered plates to propose a third epoch around 250–51 A.D., highlighting regional variations in time‑reckoning.
