A solar year on Altris is 375.1 days. Most calendars are based on a solar year; however, some are based on a lunar year or some other method (like lizardmen and dwarves). Many of the calendars are in dispute with the other calendars, mostly because they were created by other races or kingdoms and mark events the other races or kingdoms do not feel to be significant. As to which is the most accurate, on the gods would know, however some scholars claim they are even confused.
Based on the lunar revolution of Elluen, a small distant blue moon that only those with exceptional vision or a lens can see. Elluen takes 10 years to make a single revolution around Altris.
The elves gather at what is believed to be the ruins of the first elven city, where only a ceremonial platform remains intact. The platform holds three statues of elven women. The first cups her hands to her side and is looking into her hands. Her hands make a small hole which holds a small lens. When the moon clears the eastern horizon, it lights up the lens and bathes a pedestal in blue light. The center one holds a small ring over a stone bowl of water, when the moon is at its apex it shines light into the bowl causing the water to glow, this signifies the new year. And the last holds a scepter, when the moon reaches the proper location in the western sky it strikes a crystal in the scepter causing it to glow brightly. These three statues showing the starting dates of the elves three prized celebrations. Each of these celebrations last for one year.
Elven months are seasonal based. Each month consists of a full season; therefore, a calendar date may be read as the 35th day of the 7th winter of the year 340. Considering each elven year is equal to 10 solar years the date would equate to the 35th day of the year 3407 as compared to other calendars. The elven calendar supposably starts at the end of the great war, however, many scribes and scholars still argue about in what year the war ended. Any calendar created by the elves prior to the great war has yet ot be found.
