The Cultural Routes of Solar and Sidereal Calendar Systems
Hypothesized Route B: The Journey of the Maha Sakarat Era through the Maritime Route (Srivijaya–Champa–Khmer)
Info
In addition to its transmission into Pyu culture, the Indian calendrical system also spread southward into the maritime regions of Southeast Asia. It was adopted by the Java–Malay cultural sphere, including the Srivijaya Empire in Sumatra, Java, and Borneo. From there, it continued eastward via maritime routes into the ancient domains of Champa and Cambodia. In these regions, the sidereal–solar calendrical system consistently retained the name Mahasakarat (Great Era), directly derived from Indian tradition. Over time, calendrical knowledge from ancient Cambodia spread into the Lavo Kingdom and was subsequently transmitted in two directions: one toward Sukhothai and the other continuing on to Ayutthaya.
