Gemini Horoscope for December 2025

This is an interesting month for you, Gemini, with plenty of good ideas, and with the key relationships in your life looming large. In the midst of the quirkiness of the recent Mercury Retrograde, you might have been mulling over your entire relationship dynamic, a factor that continues through December’s first half, with the gradual winding down of the post-retrograde shadow period. The recent Scorpio New Moon from the previous month also activated your partnership sector and was in a grand trine with Jupiter, that sector’s ruler, along with Neptune in the last degree of Pisces. Jupiter featured and located in your sector of values and finance may perhaps indicate some specific involvement there. A very real potential exists for important others in your life to contribute to your growing sense of who you are. This involves how your internal principles and the values that you uniquely posses make up the true basis for your social sense, career decisions, and future goals. With Pluto continuing to reside in Aquarius, you are still enjoying the benefits of changeful developments concerning your beliefs and worldview, while the surprises and novel realizations regarding your very identity continue, thanks to Trickster Uranus on your solar chart’s ascendant. The fundamentally innovative and rebellious trends of these consequential months continues to inform your activities. As the December month continues to unfold, and as the Mercury shadow period winds down, and the December 19th New Moon dawns, close to your chart’s midheaven, vocational priorities take center stage and you might be dealing with these with a different sensibility than before. As you better integrate work and your own private principles and values, allowing these to predominate, you more fully emerge into what can be seen as your own independent way of authenticity – which becomes the real point.

Previous New Moon – from November 19th
December opens downstream of headwaters of the Scorpio New Moon which took place on November 19th, and activated your sixth sector of work, wellness, and the subtle ways of being that shape your everyday life. This lunation arrived with the Moon in a rare conjunction with Mercury Cazimi, highlighting an aspect of your health and wellness habits or underlying energetic patterns that may have been beneficial for you to recognize. The grand kite formation linking this New Moon to Uranus in Taurus, Jupiter in Cancer, and Saturn and Neptune in Pisces offered a flash of recognition around what lights you up, as well as, perhaps, what drains you. As December begins, this lunation continues unfolding in quiet layers, revealing what may need simplification or deeper attunement for you to feel grounded and aligned.

Mercury Direct and Recovering, since November 29th
Your ruling planet Mercury stationed direct a few days before the month begins, on November 29th, turning the beginning of December toward clarity, though slowly and with nuance. As Mercury retraces its retrograde degrees and reenters Sagittarius on December 11th, communication may feel steadier. Misunderstandings may resolve or soften as important context returns. As Mercury moves from your sixth into your seventh sector, the integration shifts into the relational sphere. Insights gained in late November may now seek expression through conversations, negotiation, and the ways you connect with others.

Gemini Full Moon – December 4th
The Full Moon in your sign on December 4th illuminates your first sector, highlighting identity, self-expression, and the evolving story you are stepping into. With the Sun opposite in your seventh sector, relational dynamics and questions of reciprocity may rise to the surface. This Full Moon and Sun opposition also forms a same-degree grand cross with the lunar nodes, creating a subtle sense of pivot or karmic turning. Old patterns may resurface alongside a clearer understanding of the choices that support your growth. It can feel like a culmination of the inner work initiated at the Scorpio New Moon, offering a moment of clarity that is both vulnerable and energizing.

Jupiter Trine Saturn – Ongoing Through Mid-December
The supportive trine between Jupiter in Cancer and Saturn in Pisces continues through mid-December, creating a stabilizing current between your second sector of resources and your tenth sector of vocation. You may notice a quiet coherence forming between what you value and how you wish to show up in the world. Creative ideas or long-term goals may feel more grounded or integrated. This influence encourages steady progress rather than urgency, inviting trust in the slow architecture of your path.

Sun, Mars, and Venus Square Saturn–Neptune Throughout the Month
Throughout December, the Sun, Mars, and later Venus all in late degrees of Sagittarius activate square aspects to Saturn and Neptune in Pisces, which precede the planet’s ingress into Capricorn. This creates tension between your seventh sector of partnership and your tenth sector of purpose. You may sense friction between personal needs and shared commitments or between the desire for clarity and the presence of ambiguity. Neptune’s influence may blur expectations, while Saturn calls for integrity and discernment. Instead of pushing for certainty, these configurations invite curiosity about what is emerging and where your energy naturally wants to flow.

Neptune Stations Direct – December 10th
Neptune stations direct in your tenth sector on December 10th, which can magnify questions around vocation and long-term direction. Station periods often heighten the archetype, and you may feel a blend of intuition and imagination mixed with some uncertainty or confusion. What surfaces may not be concrete but may reveal something deeply meaningful about your sense of wider worldly purpose, calling, or the underlying motivations guiding your choices.

Mars Enters Capricorn – December 14th
Mars enters Capricorn on December 14th, activating your eighth sector of shared resources, intimacy, and psychological depth. In the sign of its exaltation, Mars moves with steadiness and focus. You may feel called to address shared finances, emotional complexities, or deeper truths within your close connections. This transit offers courage and stamina for the more layered aspects of your inner world. If intensity arises, consider what is being asked of you at a deeper level.

Sagittarius New Moon – December 19th
The Sagittarius New Moon of December 19th lands in your seventh sector, opening a new chapter in partnership and relational exchange. Conjunct Venus and square Saturn and Neptune, this lunation highlights patterns around connection, commitment, and compassion. New conversations or shifts in dynamics may begin to take shape. There is an invitation to clarify what reciprocity means for you now and how your relationships reflect your evolving sense of self.

Sun Enters Capricorn – December 21st
The Sun enters Capricorn on December 21st, marking a significant turning of the seasonal wheel. For you, this shift into your eighth sector brings attention to intimacy, interdependence, and emotional renewal. After the illumination of the Full Moon earlier in the month, this moment offers grounding and a clearer sense of what feels true beneath the surface. It is a time to honor the deeper cycles shaping your growth.

Venus Enters Capricorn – December 24th
Venus enters Capricorn on December 24th, softening the terrain Mars has been activating. This transit brings warmth, understanding, and a gentler tone to vulnerable spaces. Topics around trust, shared resources, or emotional openness may feel more approachable. It is a reminder that intimacy grows through consistency, presence, and mutual care.
