Moon calendar: September 1987
The phases of the Moon are the changes in the illuminated part of the Moon visible from Earth over a cycle of about 29.5 days. In astrology, this cycle is measured by the angle between the Sun and the Moon. The new moon is the moment of conjunction, when the Sun and Moon are at the same degree; the full moon is the opposition, when the two are at opposite ends of the zodiac. Between these two points lie the phases in which the Moon waxes and wanes. Astrologers usually divide the cycle into eight phases, each corresponding to a 45-degree range of the Sun-Moon angle.
