As this work is a purely literary creation, in which the story is set in a completely unknown era, devoid of any sciences, customs, cultures, or religions that have been ingrained in civilizations known to man until the modern world, it became necessary and essential to create a unique and peculiar calendar that would satisfy the myths, traditions, and gods inherent to those Eras and Times. It is crucial to emphasize that the Calendar of Ernt-nador, the Known World, was entirely written in the ancient language called Idhílion, the language of the gods of Anahkólion who lived on Mount Naumathar. Some peoples of Ernt-nador, descendants of the Lineages of Anahkólion, mistakenly believe that the language originated in Ernthys and also attribute its creation to the wizard Yondar. However, the language emerged long before the First Era of Anahkólion, and Yondar also hails from there. This confusion is attributed to the passage of time over the Eras, causing many facts to be discredited and turned into legends and myths without any foundation. The Calendar of Ernt-nador, or the Known World, as it was called by some peoples, was formulated in Wol-kunt with the participation of Yondar, the Master of the Wizards, and several star scholars, along with Kolir, the king of Khiurthi—now known as Thiurethi. This occurred during the Time of Kings, but for many, it was adopted shortly before the mid-point of the Time of the Goddesses, following the Time of Shadows. This was due to the need for a more accurate system of time measurement in days, rather than the observation of the four moon cycles, which had been used for a time after the winter and summer Cycle count was abolished. It is important to note that the counting of the Cycles in Anahkólion was very different from that of Ernt-nador. In Anahkólion, a Cycle lasted about 19 months, consisting of approximately two-thirds and a little more of winter, whereas in Ernt-nador, 14 months and some days were counted, with half being winter and half being summer. This was due to the fact that Anahkólion was located further south. After spending years observing and studying the moons more deeply, Yondar realized that they followed cycles and changed, most of the time, every seven days on average. Of course, there were small variations, but he chose to disregard them as they were too insignificant. He also noted, over the years, which were previously counted by the twelve lunar phases, that the time cycles that divided the seasons of the year restarted after approximately 363 to 366 days had passed. From the discovery of the approximate number of days required for the repetition of lunar cycles, information considered of vital importance for the formal construction of the year, Yondar began to ponder the question of dividing this period. Since the moons changed on average every seven or eight days, with some variations depending on the time of year, Yondar decided that the initial total number for the month would be, as in the Time of the Goddesses, 28 days. The 28 days corresponded to the partial or complete passage of the four moons: New Moon of Akrindos, Waxing Moon of Thandius, Full Moon of Jious, and Waning Moon of Monrthis. The 28 days of the month were divided into four blocks of seven days, in accordance with what occurred during the Time of the Goddesses, where the seven days corresponded to the development and mapping, from beginning to end, of the cycle of each current moon. However, these seven days would no longer bear the same nomenclature that had been attributed to the days during the Time of the Goddesses, but rather they would be given names of great significance in the new time-counting system. The group of seven days was given the name Quanthan, which could be translated into our language as "Rotation." Having provisionally decided on the 28 days of the month and the Quanthan, Yondar, before making any calculations to define the months of the year, preemptively removed 5 days from the 365, which would not be part of any month but would be placed in order at the end of all the months of the year. These five days, however, would be of fundamental importance, as they would be offered to the gods as a form of homage. With the remaining 360 days, the wizard Yondar performed the division by the initial number of days in the month, which was 28, ultimately arriving at the result of 12 months. In the end, Yondar found that 24 days were left from the total of 360, which could not form a thirteenth month, nor could they be left out of the calendar, as it would not function properly without them. Thus, Yondar decided to incorporate the remaining 24 days into most of the months that would make up the year of Ernt-nador, the Known World.
