Void of course Moon

The “void of course” Moon is the span from the Moon's last exact aspect to a planet until it leaves its sign. In astrological tradition these hours are not recommended for starting important things, signing contracts or making big purchases: what is begun then is said not to take root. This is tradition, not scientific fact; many people simply use such hours to rest and finish what is already under way.
