Full Moon December 2025 Astrology

The full moon on December 4, 2025, is at 13°03′ Gemini. It makes no planetary aspects and aligns with no significant fixed stars. However, Jupiter trine Saturn and Uranus sextile Neptune are strong influences under one degree orb. Mercury forms a Grand Trine aspect pattern with Jupiter and Saturn, making each planet more powerful.

Full Moon December 2025 Meaning

Sun opposite Moon brings your home, family, and intimate relationships into sharper focus for the following two weeks of this moon phase. Opposing forces, such as work versus home or what you need versus what you want, create inner tension and external pressures. This polarization can lead to conflict and crises that drain your energy.

However, heightened feelings and intuition make you more receptive and aware of relationship dynamics. Greater clarity and objectivity help you find emotional balance and security. Modifying your behavior and reactions can relieve tension and resolve relationship problems.

Excited Optimism

Uranus sextile Neptune brings concern about the future, generational speculation, excited optimism, and religious reformation. It raises philosophical questions about technological breakthroughs, such as artificial intelligence, that neither traditional religion nor science can explain. A desire to understand how you are connected to others at the mass-conscious level can promote a spiritual awakening.

Deal-Making

Mercury trine Jupiter brings optimism, big ideas, grand plans, good luck and good news. Tolerance, honesty and openness ensure friendly communications; perfect for discussing, debating, cooperating, collaborating, planning and negotiating. Agreements, partnerships and deals can be made with confidence. Disagreements can be overcome and arguments avoided.

Mercury trine Saturn brings logical, careful, thorough, exact and organized thinking. It favors consolidating, securing, cementing and committing; perfect for formal discussions and negotiations, important decisions, long-term plans, deal-making, and contract signing. Self-discipline, prudence, and a practical outlook ensure lasting results.

Jupiter trine Saturn is a perfect balance of optimism and realism, enthusiasm and patience, idealism and practicality. It brings integrity, honesty, steady growth, and common sense. Sustained ambition and constancy of purpose lead to significant and enduring achievements.

The Grand Trine aspect pattern indicates abundance, talent, competence, skillfulness, and striving for harmony and perfection.

Full Moon in the Bull

The December 2025 full moon is in the Sign of Gemini. But because of the precession of the equinoxes, it is in the Constellation of Taurus.

A Full Moon in the Taurus Constellation gives ambition, determination, persistence, loyalty, practicality, reliability, steady emotions, self-reliance, and conservatism. However, it can also cause stubbornness, possessiveness, smugness, jealousy, and an overly sensual and fun-loving nature.
