  1. New Moon – Beginnings, fresh starts, intention setting.
  2. Waxing Crescent – Growth, learning, building momentum.
  3. First Quarter – Decisions, challenges, taking action.
  4. Waxing Gibbous – Refinement, preparation, progress.
  5. Full Moon – Clarity, fulfillment, emotional peak.
  6. Waning Gibbous – Sharing wisdom, gratitude, evaluation.
  7. Last Quarter – Release, transformation, closure.
  8. Waning Crescent – Rest, reflection, spiritual connection.

By knowing your moon phase, you can understand when to take action, when to rest, and how to align your life with lunar cycles.

The Moon Phase Astrology Calculator uses astronomical data and your chosen date to determine the moon’s exact position and phase. Here’s the basic process:

  1. Input the date (birth date or any desired date).
  2. Calculate moon’s position in relation to Earth and Sun.
  3. Determine the phase based on illumination percentage.
  4. Display the result with astrological interpretation.

🛠 How to Use the Moon Phase Astrology Calculator

Follow these simple steps to use the calculator:

  1. Enter the date for which you want to know the moon phase.
  2. Click the calculate button to process the data.

📅 Formula Behind the Moon Phase Calculation

While the exact astronomy can be complex, the general concept is:

Illumination Percentage = (1 – cos( Moon Age × (360° / Synodic Month) )) / 2 × 100

Where:

  • Moon Age = days since last New Moon
  • Synodic Month = average 29.53 days

From the illumination percentage, the calculator determines which lunar phase you are in.
