December Cosmic Calendar

 

December 2nd: Venus sextile Pluto ~ 4:06am EST
On Tuesday, December 2nd, Venus forms a sextile to Pluto at 4:06am EST, setting the tone for the day ahead. This transit brings a focused, purposeful energy that is ideal for collaborating with others and working toward shared goals. Conversations cut through surface-level chatter, making it easier to get to the truth of a situation and recognize what truly matters. In this space, intimacy can deepen, connection can strengthen, and transformative progress becomes possible. This transit may also heighten magnetism and passion within relationships, revealing the power of mutual vulnerability and depth.

December 4th: Full Moon in Gemini ~ 6:14pm EST
On Thursday, December 4th, the Full Moon in Gemini perfects at 6:14pm EST, with the Moon at 13 degrees Gemini and the Sun opposite at 13 degrees Sagittarius. Both luminaries square the North and South Nodes, lending this lunation a fated quality, a sense of being nudged forward into growth. We may feel the pull to evolve and move on, even if there’s a little hesitation about stepping into what comes next.

The Full Moon in Gemini is quick, curious, and mentally active. Thoughts arrive rapidly, ideas multiply, and the desire to learn, read, speak, or seek answers may heighten. This is an inherently social moon, one that encourages conversation, exchange, and expression through both voice and written word.

With the Moon in the second decan of Gemini, ruled by Venus, creativity flows more freely. Collaboration is emphasized. This is an invitation to not hold your visions too tightly, but to share, connect, and co-create. Banter, brainstorming, and playful dialogue with friends, family, and partners all feel especially uplifting now.

As the last Full Moon of 2025, this moment also offers a closing arc. We have an opportunity to release outdated thinking patterns and set intentions around clearer, more aligned communication going forward.

December 5th: Sun square Nodes ~ 7:21am EST // Mars trine Chiron ~ 5:03pm EST
On Friday, December 5th, the Sun squares the Nodes of the Moon at 7:21am EST, extending the evolutionary tension sparked by yesterday’s Full Moon. This aspect can heighten the urge to make changes while simultaneously amplifying caution, doubt, or attachment to what feels familiar. The work of the day lies in balance. Honor the call toward growth, but approach it with awareness, grounding, and consideration. Change is on the horizon, but it’s worth pausing to ensure you’re prepared and supported before taking the leap.

Later at 5:03pm EST, Mars forms a trine to Chiron, a transit that has been building all week and continues to resonate through the weekend. This is a restorative and empowering influence, encouraging a stronger connection between body and mind. It is time to tend to your physical needs, make supportive adjustments to your lifestyle, and release tension stored in the body. Compassion toward yourself goes a long way under this influence. Healing happens not through force, but through patience, presence, and gentleness.

December 6th: Mercury trine Jupiter ~ 8:04am EST
On Saturday, December 6th, Mercury trines Jupiter at 8:04am EST, an influence that extends throughout the day. This transit sparks the mind, lifting enthusiasm and opening the door to expansive thinking. Curiosity leads, and ideas may flow more freely, making it easier to connect with others through conversation, shared interests, and lively exchanges. The energy here is quick, bright, and optimistic, excellent for dreaming big, exploring possibilities, and taking steps to bring your ideals into form.

December 7th: Mercury trine Saturn ~ 11:57am EST
On Sunday, December 7th, Mercury trines Saturn at 11:57am EST. While yesterday’s energy leaned toward excitement and possibility, today brings grounding and clarity. This is a productive influence that supports planning, organization, and steady progress toward long-term goals. Saturn’s presence adds focus and discipline, helping us think practically and move with intention. Today we can lock into a groove, map out next steps, and create structure to support the big dreams we’ve been envisioning.

December 8th: Mars square Saturn ~ 7:15pm EST
On Monday, December 8th, Mars moves into a square with Saturn at 7:15pm EST, a transit that has been building over the weekend and lingers through midweek. This aspect can slow our momentum and bring awareness to exhaustion, responsibility, and the weight of everything we’ve been carrying. The astrology of the past few months has been intense, and this moment highlights accumulated burnout, asking us to recognize our limits and tend to our wellbeing.

Fatigue, soreness, or a sense of depletion may surface, and while Saturn may stir guilt around productivity, it’s important not to push yourself past your capacity. Rest is not avoidance; we can instead look at it as fuel. Give yourself space to pause, replenish, and honor what your body is communicating. Recovery is part of the process, and this transit reminds us that stepping back is often what allows us to move forward with strength and clarity.

December 10th: Neptune Rx ends ~ 7:23am EST // Mercury opposite Uranus ~ 2:59pm EST
On Wednesday, December 10th, Neptune stations direct at 7:23am EST, ending its retrograde at 29 degrees Pisces. Neptune dipped briefly into Aries earlier this year before sliding back into Pisces, and during its several-month retrograde we may have felt disoriented or unsure of what to trust, like perception itself was shifting. Retrogrades invite deeper attunement to instinct, intuition, and inner navigation. When we can’t see the path clearly, muscle memory of the spirit becomes our guide.

As Neptune turns direct, some of the fog begins to lift, but the lesson remains: stay in relationship with your inner knowing. Nourish your intuition so that when the mist returns (as it inevitably will), you move through it with steadiness rather than fear.

Later, at 2:59pm EST, Mercury opposes Uranus, adding electricity to communication. Words may come out abruptly, unexpectedly, or with a jolt of truth. Others may surprise you, and you may surprise yourself. This transit stirs rebellion, provocation, and the urge to shake things up. Conversations crackle with unpredictability, and the desire to break patterns is strong.

December 11th: Venus square Nodes ~ 12:42am EST // Mercury trine Neptune ~ 5:19am EST // Mercury enters Sagittarius ~ 5:39pm EST
Thursday, December 11th is a highly active day in the sky. We begin with Venus squaring the Nodes of the Moon at 12:42am EST, which may pull people or memories from the past back into our orbit. This can create a sense of being stretched between familiarity and growth, between someone who offers comfort but limits expansion, and new possibilities that feel exciting yet outside your comfort zone. There’s no pressure to resolve this tension immediately, but it's a good time to ponder what it is you want and hope to bring into being around these connections.

At 5:19am EST, Mercury trines Neptune, bringing a dreamy, imaginative tone to the day. Compassion deepens, intuition strengthens, and ideas flow through like channels of inspiration rather than linear thought. Later, at 5:39pm EST, Mercury re-enters Sagittarius, a placement we experienced earlier this season before its retrograde took it back into Scorpio. Mercury will remain in Sagittarius until January 1st, inviting curiosity, exploration, and broader perspective. This transit encourages us to stretch our thinking, seek new experiences, and consider the world through unfamiliar lenses. Travel is highlighted, whether to distant places or simply somewhere new in your own hometown.

Adventurousness is rewarded now. If you have natal Mercury in Aries, Leo, Libra, Sagittarius, or Aquarius, this buoyant energy may feel especially uplifting and stimulating. For those with Mercury in Taurus, Cancer, Scorpio, or Capricorn, the effect may be subtler or more neutral. And if your Mercury is in Gemini, Virgo, or Pisces, you may feel challenged by the shift. You could find yourself wanting clarity or precision where Sagittarius prefers big-picture thinking. Try softening your perspective and opening to what wants to expand. Sometimes, loosening control is what allows the horizon to widen.

December 13th: Mercury sextile Pluto ~ 11:31am EST
On Saturday, December 13th, Mercury forms a sextile to Pluto at 11:31am EST. This is a highly focused transit, one that sharpens perception and heightens awareness of subtle details. It encourages us to look beneath the surface, to read between the lines, and to follow intuitive threads toward deeper truth. This is excellent energy for investigation, research, and uncovering what might normally go unnoticed.

With Mercury now in Sagittarius, curiosity is amplified, and what once felt intimidating may now appear as an intriguing challenge. There’s a sense of mental courage here that shows up as a willingness to explore, question, and pursue understanding with enthusiasm rather than hesitation.

December 14th: Mars square Neptune ~ 6:43am EST // Sun trine Chiron ~ 7:36am EST 
On Sunday, December 14th, Mars squares Neptune at 6:43am EST, a transit that has been building over the weekend and lingers through midweek. This aspect can slow momentum and cloud direction, leaving us unsure of which step to take next. It may feel as though you’re moving through familiar terrain but suddenly can’t remember the path, like you missed a turn you’ve taken effortlessly a hundred times before. Confusion, distraction, or a pull toward escapism may surface, making it tempting to check out rather than take action. Grounding is key here; presence will be your anchor.

Also today, the Sun trines Chiron (exact at 7:36am EST), offering a stabilizing counterbalance. This supportive influence bolsters confidence and strengthens the willingness to face vulnerability rather than retreat from it. Together, these energies encourage us not to abandon the challenge, but to meet it gently. We can do this by showing up, step by step, even when clarity is still forming.

December 15th: Mars enters Capricorn ~ 2:33am EST
On Monday, December 15th, Mars enters Capricorn at 2:33am EST, where it will remain until January 23rd. Mars is exalted in Capricorn, so its energy is strong, grounded, and highly expressive here. This transit supports strategy, disciplined action, and showing up with steady, consistent effort. It’s especially beneficial for those who work independently or from home, as it strengthens focus, resilience, and self-direction.

Though this isn’t a fast-paced transit, it is an efficient one. Mars in Capricorn favors deliberate steps over rushed movement. It helps us avoid cutting corners, stay committed to the task at hand, and produce work of higher quality.

People with natal Mars in Taurus, Virgo, Scorpio, Capricorn, or Pisces often thrive under this energy, finding it easy to align their output and momentum. Those with natal Mars in Gemini, Leo, Sagittarius, and Aquarius tend to experience this transit more neutrally, neither especially boosted nor challenged.

Natal Mars in Aries, Cancer, and Libra may find this period more demanding. Aries Mars can struggle with the slower, steadier pace and may need to temper impulsivity. Cancer and Libra Mars may feel stretched by the independent, self-driven tone of the transit, preferring collaboration or support. Some conscious compromise and adjustment will help navigate this period with greater ease.

December 16th: Sun square Saturn ~ 11:33pm EST
On Tuesday, December 16th, the Sun squares Saturn at 11:33pm EST, a tense transit we’ll feel building throughout the day. This energy can amplify loneliness or make it harder to connect with others in a soft, open way. It may feel like it’s all work and no play, like you have to stay hyper-focused and organized or everything could fall apart. Remember, that pressure isn’t entirely accurate. Balance can provide some much needed relief. 

This transit can make us overly critical and exacting, creating a sense that nothing is ever quite good enough. Do your best, then step back. Let things breathe. Give yourself space to shift gears and return later with a clearer, refreshed perspective.

December 18th: Venus trine Chiron ~ 4:16pm EST
On Thursday, December 18th, Venus forms a trine to Chiron at 4:16pm EST. This is a gentle, supportive transit that favors relationships and emotional healing through our bonds with others. A trine is a harmonious aspect, allowing both planets to bring out the best in each other. Here, Venus’s warmth and connection blend seamlessly with Chiron’s healing influence.

We may find ourselves opening up more easily, connecting more deeply, and feeling supported by the people around us. This transit can also help strengthen self-esteem, especially around appearance, self-expression, and the confidence to show up authentically.

With tomorrow’s New Moon building, there’s a natural pull toward softer, quieter energy. A calm evening, either solo or with people who enjoy shared silence, may feel especially nourishing.

December 19th: New Moon in Sagittarius ~ 8:43pm EST
On Friday, December 19th, the New Moon in Sagittarius perfects at 8:43pm EST. This lunation occurs with the Sun and Moon conjunct at 28 degrees Sagittarius, forming squares to Saturn and Neptune. This is a potent New Moon that invites big dreams, exploration (whether outward or inward) and a release of limiting beliefs or external pressures that have been weighing you down.

The Saturn/Neptune square highlights the need to balance idealism with grounded planning. Neptune encourages vision, while Saturn reminds us to bring structure and intention to those dreams. This is an excellent time to learn something new, begin a class or course of study, or make (or plan) a meaningful journey. Even long-term travel goals, those “someday” bucket-list adventures, are worth dreaming up now.

This New Moon falls in the third decan of Sagittarius, ruled by the Sun, inspiring confidence, warmth, and open-hearted courage. Its energy encourages stepping into something new with optimism and bravery.

Those born between April 15th–19th, August 17th–21st, and December 17th–21st may feel this New Moon most strongly and receive its biggest boost.

December 20th: Mercury square Nodes ~ 10:59am EST // Sun square Neptune ~ 8:01pm EST
On Saturday, December 20th, two major transits shape the day. The first arrives at 10:59am EST as Mercury squares the Nodes of the Moon. This aspect can create a mental snag or sense of being caught in an outdated perspective that limits forward movement. The North Node pulls us toward growth and evolution, asking us to acknowledge the ways we may be contributing to our own stagnation. Conversations may feel circular or repetitive, as though no real progress is being made. Finding a way to interrupt the cycle, even briefly, can help shift the energy.

Later, at 8:01pm EST, the Sun squares Neptune, casting a dreamy, imaginative tone over the evening. This can bring whimsy and creative fantasy, but also moments of confusion or disorientation. Sensitivity to others’ moods and energies may be heightened, so gentle boundaries and grounding practices can be especially supportive.

December 21st: Venus square Saturn ~ 12:08am EST // Jupiter square Chiron ~ 5:07am EST // Sun enters Capricorn ~ 10:03am EST
Happy Capricorn Season and blessed Yule! Today brings three major transits. The first arrives at 12:08am EST as Venus squares Saturn. This aspect can highlight feelings of responsibility or heaviness in relationships. We may feel burdened by our connections, or worry that we’re burdening others. Creative collaborations and teamwork can feel strained, either because others aren’t contributing equally or because our ideas don’t seem to be fully recognized.

Jupiter also forms a square to Chiron at 5:07am EST, a transit that’s been building over the past week and will carry us through the end of the year. This energy can stir old wounds around spirituality, belief systems, or previous experiences with religion. It may also bring up feelings of being blocked from expansion or personal growth by external circumstances or the people around us. While both of these transits can feel heavy in theory, they offer significant opportunities for healing. Honest self-reflection, gentle truth-telling, and directing compassion inward can help us move through and beyond what arises.

At 10:03am EST, the Sun enters Capricorn, where it will remain until January 19th. Capricorn season is ideal for focused work, ambition, strategy, and slow-and-steady progress. As the sign of cardinal earth, Capricorn is about carving out a self-directed path, one built with intention, durability, and long-term stability. Rather than seeking quick fixes, this energy invites us to construct something meaningful that can grow stronger over time.

Capricorn Season also ushers in the Winter Solstice (or Summer Solstice in the Southern Hemisphere). The Solstice is a powerful turning point when the balance of light and dark is at its most extreme. In the Northern Hemisphere, today marks the longest, darkest day of the year, a reminder to hold to the light within and around us. Working with candles, tealights, or a glowing hearth can symbolize resilience, warmth, and renewal. For those in the Southern Hemisphere, this is Litha, the longest day of the year, celebrating sunlight, abundance, and flourishing growth.

December 24th: Venus square Neptune ~ 12:30am EST // Venus enters Capricorn ~ 11:25am EST
I hope you’re having a lovely holiday season. On Wednesday, December 24th, two Venus transits color the day. At 12:30am EST, Venus squares Neptune, a dreamy, ethereal energy that we’ll feel strongly through the first half of the day. This aspect encourages curiosity, imagination, and creative flow. It’s especially supportive for artists, writers, and anyone who works with intuition or stream-of-consciousness expression. While it can help us see the beauty in others, it may also make it easier to gloss over issues or avoid addressing them. Enjoy the inspiration, but stay grounded in awareness.

Later, at 11:25am EST, Venus enters Capricorn, where it will remain until January 17th. This transit emphasizes commitment, consistency, and long-term dedication in relationships and creative pursuits. It invites us to stay the course, be dependable, and strengthen bonds through steady effort and resilience.

Those with natal Venus in Taurus, Virgo, Scorpio, Capricorn, or Pisces tend to enjoy this energy most and may notice a boost in creativity and romance. Natal Venus placements in Gemini, Leo, Sagittarius, and Aquarius experience this period more neutrally. Those with natal Venus in Aries, Cancer, or Libra may need to lean into compromise, adjust expectations, and practice patience with others during this time.

December 27th: Mercury trine Chiron ~ 7:14pm EST
On Saturday, December 27th, Mercury forms a trine to Chiron at 7:14pm EST. This supportive transit brings clarity to the mind and creates space for healing through communication. It helps us recognize and release unhealthy habits or thought patterns, allowing us to approach situations with greater objectivity, compassion, and optimism. Mercury’s influence opens the door to honest expression, while Chiron encourages vulnerability, making it easier to speak from the heart and share truths that may have felt too tender to voice before.

This is an excellent day for journaling, writing, and sorting through your inner landscape on paper. Insights can arrive more fluidly, and conversations with loved ones, friends, or trusted confidants can feel especially meaningful and restorative. If you’ve been wanting to clear the air, offer an apology, or simply articulate something that’s been lingering within, this transit provides a gentle, supportive backdrop. Overall, it’s a deeply healing energy that helps strengthen both self-understanding and the bonds we share with others.

December 29th: Mars sextile Nodes ~ 7:50pm EST
On Monday, December 29th, Mars forms a sextile to the Nodes of the Moon at 7:50pm EST. This is a pleasant, powerful transit to carry us into the New Year. We’ve felt it building since the end of last week, and its influence will stay with us as we move into early 2026. This aspect is highly motivating and encourages spiritually aligned action that feels purposeful, intuitive, and guided.

There’s a gentle push toward taking a leap of faith or pursuing something new. Inspiration flows more easily under this transit, helping us recognize opportunities or desires that may have been sitting quietly beneath the surface. Even if we feel slightly out of our element, this is a potent period for embracing change and taking thoughtful risks. Staying open to surprise and allowing yourself to improvise can lead to breakthroughs.

With Mars currently in Capricorn, there’s an added layer of grounding and stability, helping us “stick the landing” and follow through on whatever we set into motion.

December 30th: Mercury square Saturn ~ 2:15am EST
On Tuesday, December 30th, Mercury squares Saturn at 2:15am EST. This transit can bring communication blocks, stubborn thinking, and even moments of writer’s block. Self-doubt may surface, making it harder to express yourself clearly. However, there are valuable gifts here as well. With focus and persistence, this transit offers an opportunity to deepen your mastery through dedication and patience.

Though it might feel easy to become frustrated or misunderstood under this energy, it’s important not to give up. Instead, concentrate on small, achievable goals that build momentum step by step. Be gentle and compassionate with yourself and treat yourself as you would a dear friend in need of encouragement.

This marks the final major transit of 2025. I’ve truly enjoyed reading the skies for you over this past year (and for the ten years before that, wow!) and I’m excited to continue exploring the celestial rhythms with you in 2026. Wishing you a beautiful, magical close to the year. See you in the new year!
