Like the Sun, the Moon continually moves through the Zodiac, and each sign has its own significance. The Moon enters into the next zodiac sign approximately every two to three days. It is not uncommon for the Moon to enter all twelve signs within the month. Some months the moon will enter into the zodiac signs fourteen times, however, the norm is thirteen times per month.

If you are not sure what sign the moon is in, you can check the Pagan Calendar to figure out the moon signs, moon phases, and quite a lot more.

Bear in mind that magickal workings for gain, increase or bringing things to you, should be initiated when the Moon is Waxing (from Dark to Full); when the Moon is Waning (from Full to Dark), it is time for magical workings of decrease or sending away. The highest energy occurs at the Full Moon and, therefore, this is the most powerful time for magical workings. The New Moon is the next most powerful time for Magic.
