Binnya Waru, a historical figure from the Hanthawaddy Kingdom in what is now Myanmar, has several discrepancies in the chronicles regarding his key life dates. The main sources of these discrepancies are the different Burmese chronicles, such as the "Hmannan Yazawin" (Glass Palace Chronicle) and the "Maha Yazawin" (Great Chronicle), which often provide varying accounts of historical events and figures.

1. Birth and Reign: The chronicles differ on the exact birth date of Binnya Waru. Some sources suggest he was born in the early 15th century, but the exact year can vary. His reign is generally agreed to have been from 1446 to 1451, but the start and end years can differ slightly depending on the source.

2. Death: The year of Binnya Waru's death is another point of contention. While some chronicles might agree on 1451 as the year of his death, others might provide a different year, reflecting the challenges in maintaining consistent historical records over centuries.

3. Events During His Reign: The chronicles also vary in their accounts of significant events during Binnya Waru's reign. This includes military campaigns, political alliances, and internal affairs of the kingdom. These discrepancies can affect the interpretation of his impact and legacy.

These differences are typical of historical records from this period, where oral traditions, regional biases, and the lack of standardized record-keeping contribute to variations in historical accounts. For a more detailed analysis, historians often cross-reference multiple chronicles and other historical evidence to piece together the most likely scenarios.
