Void of Course Moon

The Moon is void of course from its last Ptolemaic aspect (conjunction, sextile, square, trine, opposition) to any of the other nine bodies — Sun, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto — until it enters the next True Sidereal sign.

VoC-triggering aspects may differ from tropical VoC calendars because the sign window is computed against True Sidereal Midpoint Method boundaries. This is currently the only published calendar of its kind, and the empirical track record of VoC doctrine was largely developed using tropical sign boundaries. For high-stakes timing decisions, consider consulting both systems.
