The Junagarh inscription of Rudradaman I is a significant historical record. It mentions the repair of the Sudarshana Lake, originally built during the time of Chandragupta Maurya and improved by Ashoka. The inscription specifically states that a terrible storm occurred in the year 72 of the Saka era, causing damage to the lake's embankment, which Rudradaman subsequently repaired.The Saka era is a historical calendar era. Its epoch (year 0 or year 1) is widely accepted to correspond to 78 CE. To convert a year in the Saka era to a year in the Common Era (CE), you typically add 78 to the Saka year.Given Saka era year = 72. Time in CE = Saka year + 78 Time in CE = 72 + 78 Time in CE = 150 CE.Therefore, the terrible storm mentioned in the Junagarh inscription occurred in 150 CE.
