Historical Definition
Annus Platonicus is a common month, or an age.
Meaning
The unusual breadth of the definition should remain visible: an ordinary month and an age are both offered. The entry does not supply a computation that would reconcile them or specify a universal duration. Readers should resist replacing it automatically with another familiar explanation of a Platonic year. In this dictionary, the immediate evidence is this twofold gloss. A dated operation, explicit number of days or discussion of an age in the surrounding source must decide the applicable scale.
Places to Read
Annus Aniadin. A lifespan expression rather than a fixed calendrical year.
Mensis Philosophicus. A philosophical month measured as forty days of digestion.
Periodus. The limit or duration of life.
