The Mesanoitikoth

Demons are busy people, but even they have limits. After full seasons of harduous work, they need breaks beyond those they get every six days. That's is when Mesanoitikoth comes in. It is a mid-spring holyday period that extends between the 22nd of Spring to the 65th of the same season. During that period, the fields are left to tend to themselves.
 During that period, children are released from their duties in Breeding-Citadels or Battle-School and can enjoy life. If they have noone to welcome them, they accompany their teachers in a resting location. Adults on the other hand, still havee their jobs, but can laze around more easily.
