A Measure of Peace
The five days between the end of one calendar year and the beginning of the next. During this time, no celestial bodies shine in the night sky of Creation. Mystics, prophets, priests, savants, and others attuned to the mystical studies of the occult view this time as one of portentous effects. Even the gods react with caution during this time—in the Heavenly City of [[Yu-Shan]], a grand ball is held for the duration of the five days and mortals may freely visit it during this time.
Calibration is also the only time of year that Solar Circle sorcerers may summon Demons of the Third Circle. As such, during the First Age the Solars held a great feast of their own in ancient Meru. The last feast was the start of the Usurpation.
