Overview
The lunar phases are not Moon‑only events — they are the visible expression of the Sun–Moon synodic cycle. Every New Moon, Quarter Moon, and Full Moon arises from a precise angular relationship between the Sun and the Moon. As the Moon orbits Earth, the Sun’s light reveals different portions of its surface, creating the rhythm of illumination, shadow, tension, and release that shapes the lunar month.
This index gathers all lunar phases and special events — crescents, quarters, gibbous phases, eclipses, and liminal balsamic days — into a single reference. Use it as both a technical guide to Sun–Moon geometry and a symbolic map of the Moon’s emotional storyline: beginnings, growth, culmination, integration, and renewal.
It is part of the Planetary Cycles meta‑root, which organizes all cycle‑based reference material within the ASTROFIX codex.
Phases & the Sun–Moon Synodic Cycle
The Moon’s phases are created by the Sun–Moon synodic cycle — the 29.53‑day rhythm from one New Moon to the next. As the Moon moves around Earth, the angle between the Sun and Moon changes, revealing different portions of lunar light. Each phase corresponds to a specific Sun–Moon angle and marks a turning point in the emotional and symbolic storyline of the month.
- 0° — New Moon: the seed point; instinct and identity merge in darkness
- 90° — First Quarter: friction, action, and emotional activation
- 180° — Full Moon: illumination, culmination, revelation
- 270° — Last Quarter: release, reorientation, emotional pruning
Between these major angles lie the crescents and gibbous phases — the subtle emotional transitions that shape the Moon’s monthly arc. Together, these eight phases form the synodic cycle, the most visible and intuitive timing mechanic in astrology.
Lunar Phases & Events
Sun–Moon Angle: 0° (Conjunction)
The Sun and Moon meet in the same degree of the zodiac, merging identity and instinct in total darkness. This is the lunar seed point — the moment when the old cycle dissolves and the new one has not yet taken form.
Mythic Themes:
- The void before creation; the womb of possibility
- Instinct and identity fuse into a single intention
- Invisible beginnings; quiet inner alignment
- Emotional reset; the soul inhales
Sun–Moon Angle: ~45° (Semi-square region)
The first sliver of light appears — fragile, hopeful, and reaching. The Moon begins to pull intention out of the dark and into form.
Mythic Themes:
- The first spark of becoming
- Hope, anticipation, and early momentum
- Shaping intention into action
- Emotional courage; tender beginnings
Sun–Moon Angle: 90° (First Quarter)
Light and shadow divide the Moon in half — a moment of tension, choice, and forward push. The cycle demands action.
Mythic Themes:
- The hero’s first challenge
- Friction that tests commitment
- Emotional activation; decisive movement
- Building structure; confronting obstacles
Sun–Moon Angle: ~135° (Waxing sesquiquadrate region)
The Moon swells toward fullness, refining and perfecting what began at the New Moon. This is the polishing phase — the emotional fine‑tuning before revelation.
Mythic Themes:
- Refinement, adjustment, improvement
- Heightened awareness and anticipation
- Preparing for culmination
- Emotional discernment; aligning intention with outcome
Sun–Moon Angle: 180° (Opposition)
The Moon stands fully illuminated — nothing hidden, everything revealed. This is the climax of the lunar story, where truth rises and emotional clarity peaks.
Mythic Themes:
- Revelation, culmination, illumination
- Heightened emotion and intuitive clarity
- Relationship dynamics illuminated
- The harvest of the New Moon’s intention
Sun–Moon Angle: ~225° (Waning sesquiquadrate region)
After the revelation of the Full Moon, the Moon begins to share, teach, and distribute what has been learned. This is the phase of emotional digestion.
Mythic Themes:
- Integration, understanding, storytelling
- Processing the Full Moon’s truth
- Generosity, gratitude, wisdom-sharing
- Emotional assimilation
Sun–Moon Angle: 270° (Last Quarter)
The Moon is half‑lit again, but now the light is waning. This is the reckoning phase — the moment of release, simplification, and emotional pruning.
Mythic Themes:
- Letting go; clearing what cannot continue
- Reorientation and course correction
- Internal conflict → resolution
- Preparing for closure
Sun–Moon Angle: ~315° (Waning semi-square region)
The Moon thins into darkness. This is the dreamtime — the liminal descent before the cycle ends.
Mythic Themes:
- Surrender, rest, retreat
- Dreaming, intuition, symbolic thinking
- Completion of the lunar cycle
- Emotional release; dissolving attachments
Sun–Moon Angle: ~330°–360° (Final phase before New Moon)
The Moon enters its most mystical phase — the final dissolution before rebirth. This is the phase of endings, forgiveness, and karmic clearing.
Mythic Themes:
- Closure, dissolution, release
- Healing, forgiveness, ancestral clearing
- Visioning the next cycle
- Highly intuitive, liminal, dreamlike energy
Definition: A New Moon aligned with the Moon’s Nodes — the Sun, Moon, and Earth form a straight line.
Mythic Themes:
- North Node Solar Eclipse — destiny gates open; future pulls forward
- South Node Solar Eclipse — karmic release; old patterns collapse
- Shadow + light reset identity and instinct
- Powerful new beginnings with long arcs
Definition: A Full Moon aligned with the Moon’s Nodes — Earth’s shadow falls across the Moon.
Mythic Themes:

- South Node Lunar Eclipse — emotional purging; ancestral clearing

- Major culmination with karmic weight
Definition: A second Full Moon in the same calendar month, or the third Full Moon in a season with four.

- Amplified intuition and synchronicity
- Unusual revelations; unexpected clarity
- Heightened magic and symbolic resonance
Definition: A Full or New Moon occurring near perigee (the Moon’s closest point to Earth), appearing larger and brighter.
