Jarus Calendar

The Jarus Calendar is a solar calendar used in the superpower nations of the Azerath Nations and Authorania. This calendar was developed by an Azerath scholar named Ylthryd Jarus and replaced the old Morthanian calendar that the Azerath Nations was using prior. This old Morthanian calendar was also used in Authorania, who developed their own version called the Aumentus Calendar. Authorania ended up adopting the Jarus Calendar when trade between the superpowers became prevalent.

History
The Jarus Calendar traces its roots back to a calendar created by the Morthanians. It is unknown when this calendar was created or who created it, however, it was used for centuries in Morthania. After Morthania collapsed, versions of this calendar were used in both Authorania and the Azerath Nations.

The Morthanian calendar was a 10 month 364 day calendar. The Morthanians would add 2 days every other year to keep it in synch.

The Azerath Nations, who already used a solar calendar, decided to adopt the Morthanian calendar in order to fix some issues with their current calendar, called the Jagaar Calendar. The Jagaar Calendar was not divided into months, but was instead divided into seasons. When the Jagaar Calendar was first created, it was based off of one year in the Pretestament Era. That year, winter was abnormally short, which threw off the year, making it a 259 day year. Due to the 6 day gap, the Jagaar Calendar was revised, making the year 362 days long. Since this was still short of the actual 365 day year and the days began to drift out of synch with the seasons, days were manually entered by the government to put the days and seasons in synch.

After Morthania fell, the Azerath Nations scholars discovered Morthania's calendar and used it to replace the Jagaar Calendar. However, this Morthanian Calendar still had issues, being 364 days long. The Azerathians did not discover that the calendar was out of synch with the seasons until several years later, in which 10 days had to be added onto the calendar in 1D 003. After this, an Azerath scholar named Ylthryd Jarus decided to recreate the Morthanian calendar, by adding a one month, shortening months and making the calendar 365 days long. He named the first month after himself and created the Jarus Calendar. Every 4 years, a day is added onto a month decided by priests, to keep the calendar in synch with the actual year.

The Authoranians adopted Morthania's calendar during the kingdom's establishment as Morthanian refugees founded the kingdom. The calendar remained relatively unchanged for centuries as High Priests added a day every year to keep the calendar in synch with the seasons. However, the calendar still drifted due to the year being 365.25 days long, so an updated calendar was established, with an added month, shorter days and three months set aside to have the extra day added to. This new calendar, called the Aumentus Calendar, was 364 days long, with one day added by priests to three designated months per year, and every 4 years, 2 days were added. It was known at the time that the true year was 365.25 days long, however, the extra day added by priests was a sacred holiday, so Authoranians kept to their broken calendar.

Adoption by Authorania
Following the Blood River War, trade between the Azerath Nations and Authorania boomed. It became clear that trade and commerce would be easier if the two nations adopted the same calendar. Since the two nations both used similar calendars, the only debate was which calendar should be adopted.

The Azerath Nations wanted to stick to the Jarus Calendar since it was more refined and only required one day to be added every 4 years to keep the calendar in synch. The Authoranians wanted to stick to the Aumentus Calendar since the added days every year was a religious holiday. The Authoranians decided to adopt the Jarus Calendar in order to keep from adding 1 day every year and 2 days every 4 years. The holiday would be celebrated every4 years, in which the priests choose to add the day either in Reinhad, Sundar or Redleaf.
