Full Moon in Astrology

A Full Moon occurs when the Sun and Moon are in exact opposition (180° apart) — the Moon is fully illuminated as the Sun shines on it from directly opposite. This marks the culmination of the lunar cycle that began at the New Moon two weeks earlier.

The Themes of Culmination

If the New Moon is for planting seeds, the Full Moon is for harvest — or for recognizing which seeds didn't germinate. Themes initiated or set in motion at the New Moon reach a peak of visibility:

• Situations come to a head
• Hidden matters come to light
• Decisions that have been building demand resolution
• Relationships and projects reveal their true nature

Emotional Intensity

The Full Moon's opposition between Sun (conscious, rational, solar) and Moon (emotional, instinctive, lunar) creates a natural internal tension — the two luminaries pulling from opposite sides of the chart. This accounts for the heightened emotional intensity many people experience around Full Moons.

The Full Moon's Sign

Each Full Moon illuminates the axis between two opposite signs:

• Full Moon in Aries / Libra axis: Self-assertion vs. relationship balance
• Full Moon in Taurus / Scorpio axis: Stability vs. transformation
• Full Moon in Cancer / Capricorn axis: Nurturing vs. achievement
• Full Moon in Leo / Aquarius axis: Personal expression vs. collective belonging

Release and Completion

Traditional astrology designates the Full Moon as the optimal time for releasing, completing, and letting go — the waning cycle (Moon decreasing) that follows is favorable for clearing, eliminating, and drawing inward.

Lunar Eclipse

When a Full Moon occurs near the lunar nodes, a lunar eclipse results — Earth's shadow falls across the Moon. Eclipse Full Moons are dramatically more powerful and often mark irreversible endings, culminations, or revelations.
