A lunar cycle lasts 29.5 days.
This means that it takes 29.5 days for the Moon to progress from New to
Full, and back again to New.
During her cycle, the Moon moves through four distinct quarters – you can easily recognize them when you look up into the sky at different times.
These phases are:
- New Moon
- First Quarter
- Full Moon
- Third Quarter
The reason these phases look different to us, here on Earth, is that there are varying amounts of sunlight reflected off the Moon’s surface. (Well, that’s not strictly true – Luna always has one face shining directly at the Sun, it’s our viewpoint that’s really moving).
Full Moon is midway through the cycle. It’s when astrologically, the Moon is 180º away from the Sun. To see this in your mind’s eye, you can imagine Sun, Earth, and Moon all in a straight line (with Earth in the middle).
It’s when Sun and Moon – our twin luminaries – are face to face, the full force of their energies meeting in the middle. AKA right where we, on Earth, stand.
