Arixi Calendar

The Arixi Calendar, the most comprehensive measurement of history of it's time, grew widespread after it's creation during the Dark Ages. The meticulous Arixi painstakingly detailed the histories of the past, a trade which grew common in the Arixian Kingdoms. This produced documentation that grew more concise by the generation, and all histories remained consistent to the calendar. The spread of the calendar's use was slow, working by generation upon generation, but it became conventional throughout the Ienne by approximately 400 Defterian.

History
The source of the written letter is unknown, but must have been created some time before 216 Protisian. Many early societies were already using the written letter as a form of sending large messages over a long distance by 216, however, and it is generally accepted that the letter came before the Avhoular Annual, which would put it before 1 Protisian, preceding even the Dark Ages.

During the Dark Ages, at the height of the First Surak Invasion of Arixi, the first known western documentation of a historical event was created. Pelagius, an Arixi commander, recorded the Battle of Filiros, which happened in 216 Protisian, so as to easily teach his future students the practice of strategy. The innovative study became commonplace for future battles, though Pelagius would only be recognized for his ingenuity long after his death. From Pelagius came Prokopios, whose records of the finances of Dhrimon found their place in the early annals of history. The latest Protisian documentation isn't even Arixi, but found it's way to the Kingdoms in the Defterian Era. This was a treatise crafted by an unidentified Godda man on the Faith of Sundri.

All of these early events took place under divided calendars, though throughout the Ienne the Avhoular Calendar was more commonplace than most. As globalization grew imminent and communications between nationalities intermingled, it became apparent that a single, united calendar would be the most efficient way of solving the misunderstandings brought up with conflicting histories and their dates. The Arixi spearheaded this change, having already reset their own calendars after the Second Surak Invasion of Arixi which demolished much of their ancient history. The practicality of the new calendar was that anything prior to the reset period was considered Protisian, where dates were already muddled. That way, past events were inconsistent but the present date remained the same for all cultures that adopted the system. By 400 Defterian, all Ienne societies had adopted it's use, as did the Surak and Sarsinians.
