Exactly one-twelfth of a Great Year. The length of a Platonic month equals 2160.4 years. The term appears to have first been coined by Carl Gustav Jung in Aion where, in footnote 84, he gives us its calculated length: 2 143 years. Two centuries earlier Voltaire had proposed the concept, but not given it this name. | Exactly one-twelfth of a Great Year. The length of a Platonic month equals 2160.4 years.

This can be calculated as Jung did from the precessional rate, as follows. In Aion, Jung used a precessional rate of 50.3608 arc seconds per year [an arc second is one-sixtieth of one-sixtieth of a degree]. This he took as the angle by which the Vernal Equinox Point changes, as seen against the stars, each year. Divide that angle into the full circle of 360º and you have the number of years which it would take to make a complete precessional cycle: 25,734.3 years. Divide that number of years by 12 for a Platonic month and you get 2 144.5 years, Jung's math is out by a year. | This can be calculated as Jung did from the precessional rate, as follows.
