Nebulonic calendar

Year numbering
The year 1 in the Nebulonic calendar is the year in which the Crossing of the Sea took place. The Crossing of the Sea is the mythical origin story of the Nebulonic people. This dating system comes from the widely popular Flowerbed of Maisad, an early work of the Old Nebulonic classical age. The Flowerbed of Maisad (named after the chief city of the Nebulones in the period from 857-1302) is a collection of poems concerning Nebulonic legends, history, and culture; it is the main source of knowledge on ancient Nebulonic belief. The first 18 songs concern matters of folklore and legend, but the next 18 deal with Nebulonic history, up to the Conversion. Song 19 details the Crossing of the Sea, and subsequent Songs relay the dates of their events by saying, for example, "A hundred years after the Crossing..." The historian and mathematician Vearōn of Narso was able to systematize this dating system using the chronicles in conjunction with the Flowerbed, and arrived at the dating of his current year as 942. Other important dates include 857 (the Rise of Maisad), 868 (the Conversion), 1302 (the Fall of Maisad), 1547 (the Foggy Mountain Migration), and 1550 (the incorporation into the Sajem Tan federation).
