Official History of the Kingdom of Kiŗaun

Several years after Badnīl Qau was crowned king of the Kingdom of Kiŗaun, his best friend, vizier, and brother-in-law Nautīr Ptor commissioned the creation of an official history of the kingdom and how Badnīl united the Kaushan tribes into a single nation. While some might say it was overly favorable of Badnīl and his family, Nautīr made sure the historian was very careful in being as fair as possible in the creation of the document. He also ensured that the document was updated up until the formation of the Eastern Principalities.
Here's the basic timeline from the book:
Note that I have not determined months yet. But, I hereby decree that the Kaushan use 10 months, each 35 days long. That's an extra 3 days, so either 3 months are one day short or 1 is 3 days short. Month is indicated below as a +x next to the year.
