At this writing, the moon is Void of Course. Every few days the moon moves through a different astrological sign. The time between leaving one sign and entering the next is described as “Void of Course,” often noted as VOC or v/c on lunar charts. The length of this period can vary from a few minutes to several hours.
I’m preparing a Spell, and wanted to research whether casting during moon VOC was advisable. My research led me to Estelle Daniels’ website, and this is what I learned.
It’s generally accepted that beginning anything which one intends to produce a tangible, real-world outcome should be avoided during moon VOC periods. Because the intent of magick is typically to affect change on the material plane (our “physical” reality), it seems to fall into this category.
A caveat: Intent is paramount. If the magickal need is urgent, Craft regardless of moon phase.
