Each month the Moon makes one complete orbit around the Earth, spending 2 or three days in each sign as it goes. As the Moon nears the end of a given sign, it passes the highest degree occupied by any other planet and goes Void of Course. It is no longer “communicating” with the other planets until it enters the following sign.
This void period could last a full day or be as brief as only a few minutes depending on the location of everything else in the sky.
When the Moon is Void actions tend to have less result, or things don’t connect completely, so it is a good idea not to start a project on a Void Moon. A first date will go nowhere. Things purchased on a Void Moon don’t get used, don’t really fit, or are somehow never quite right. If you buy groceries during this period the store will be out of what you came for, or you will end up going out to eat all week and the produce will spoil in your refrigerator. Don’t send out invitations, no one be able to come. On the other hand, you can use the energy positively to diffuse a situation – if you need to bring up a difficult subject, or think you are going to have an argument with someone – call them on a Void Moon! Nothing will come of it – you have just avoided unnecessary drama. Use void moons to work on projects you have already started, to adjust and refine things. Clean your house. Play with it – you will very quickly figure out how to best use your moons.
