The Years of Lumen is a dating system based on the foundation of the Aspirants of Lumen in the city of Lumen. The year of the group's founding is year 1, and the present year is 2360. Years using this system are marked as YL, with those before the founding marked as BL.
The system was slow to be adopted outside of Lumen, but it gained a greater following after the revelation of the Alaxaran pantheon in 673 YL (487 BA) and by the time of the Great Battle of Darkness was used across much of what is now western Evenhold. Following the battle the Years of Anharos reckoning became Evenhold's official dating system and the use of the Lumenite system dwindled. It continues to be used in the city of Lumen.
Per the Years of Anharos, the founding of the Aspirants occurred in 1160 BA, and the present year is 1200 YA.
