In astrology, planetary phases describe the relationship between the Sun and a planet. The concept is most commonly applied to the Moon, but classical astrology also uses phases for Venus, Mercury, and other planets to determine their energy expression and timing of events.

🔹 Moon Phases

The Moon’s phases are crucial for timing, emotional energy, and life cycles. There are 8 main phases:

1. New Moon – Initiation, beginnings, planting seeds.
2. Waxing Crescent – Growth, intention setting, building energy.
3. First Quarter – Challenges, decision-making, action needed.
4. Waxing Gibbous – Refinement, preparation, strengthening efforts.
5. Full Moon – Completion, culmination, illumination, heightened emotion.
6. Waning Gibbous – Sharing, gratitude, distributing energy.
7. Last Quarter – Release, adjustment, evaluation.
8. Waning Crescent – Rest, closure, reflection, letting go.
