Calendar

Syra's current calendar was created following the Elf Wars. It consists of twelve months, each named for a great hero who fell during the war. Each week has eight days, named for eight of the gods. The months are thirty days long, and sync up with Omiel's lunar cycle. The full moon is on the first of each month, and the new moon is on the sixteenth.

The days of the week are Corlsday, Yonday, Ehloday, Korsday, Pelsday, Cobsday, Moraday, and Bahamusday.

The months of the year are Adinar, Sebina, Acteus, Oberth, Hegasat, Tarliel, Nachtur, Urnaor, Esilcar, Leroit, Gedranh, and Adirnaan.

Spring begins on the 16th of Sebina, Summer on the 16th of Hegast, Autumn on the 16th or Urnaor, and Winter on the 16th of Gedranh.
