Every 29.5 days, the Moon completes one full lap around the Sun as seen from Earth — a synodic cycle measured by the ever-shifting angle between the two luminaries, from 0° back to 360°. The four primary phases are ancient; Dane Rudhyar, in his landmark 20th-century work The Lunation Cycle, refined them into eight distinct stations, each capturing a precise quality of light, momentum, and meaning. The waxing arc (New Moon through Full Moon) is the hemisphere of building and projection; the waning arc (Full Moon through Balsamic) is the hemisphere of integration and release — two halves of one breath.
Lunar Phases
New Moon
The New Moon opens the soli-lunar cycle at 0° elongation — a moment of pure emergence, instinct, and beginnings that seeds everything that follows.
Waxing Crescent
The Waxing Crescent spans 45–90° of the soli-lunar cycle — a phase of effortful emergence, where the impulse seeded at the New Moon meets its first real resistance.
First Quarter
The First Quarter Moon — Sun and Moon 90–135° apart, half-lit — is astrology's great turning point: the moment a seed-impulse must fight to become structure.
Waxing Gibbous
The Waxing Gibbous phase spans 135–180° of the soli-lunar cycle — the Moon's final push toward fullness, driven by refinement, clarification, and devoted effort.
Full Moon
The Full Moon marks the peak of the soli-lunar cycle — a moment of maximum illumination, heightened awareness, and the tension of opposites brought into the open.
Waning Gibbous Moon
The Waning Gibbous or Disseminating phase (225–270°) is the lunar cycle's great act of sharing — where insight earned at the Full Moon becomes a gift passed forward.
