December 2025 Astrology ~ The SPARK & The STONE (+Sweet & Salty Dates)

Here are some top points to know about the December 2025 Astrology. See my December 2025 Horoscope Videos/Podcasts  for more details and also in the date specific notes towards the end of this written report:

**Scroll down around midway through this report to find Sweet and Salty dates!!

TOP DECEMBER POINTS:

1. December brings us back into a less favorable ratio with double the salty aspects compared to sweet ones. You will definitely be feeling the resistance of the planets not getting along as these nuisance aspects are spread through the whole month. There will be some muck to get through to properly shed this year and prepare for the new beginnings promised by a January 2026 that is free of personal planet retrogrades. Nine sweet aspects light up the month, giving respite in between these last pushes into the New Year. I will detail the worst of the worst and the best of the best in the second half of this newsletter.

2. The Mercury retro scene…The first half of December will be spent getting out of the web of Mercury retrograde. This Mercury retrograde cycle starting October 21 as the pre-retro shadow began, the official retrograde is November 9, Mercury direct is on November 29, and the post-shadow transit goes until December 17.

Many things were sent into reconsideration during this time but this month, more clarity will develop as the month goes on. Then as of December 17, 2025 and until February 12, 2026, we have a beautiful open window free of personal planet retrogrades that will add robustness to the New Year and make it easier to launch into this year full of enthusiasm and discipline.

If you are looking to plan ahead for 2026, stay tuned in my Secret Star Portal as I have posted my 2026 Astrological Tides Planning calendar and the portal is the only place you will find that detailed planning report for the upcoming year.

3. The Eclipse Story:

Mid January will start Eclipse season again. Enjoy this break throughout December and a bit beyond!

Stay up on the eclipse storylines in process, as a member of my Free VIP community, you have access to my Eclipse Resource Page. I have updated this page with the info for your sun, moon, and rising eclipse implications for these September eclipses.

4. The major zodiac star of December is Sagittarius! This trend began in November and continues this month. We also have a strong showing of Capricorn as a sub-theme, which strengthens as the month moves on.

The Sun will be in Sagittarius from November 23 - December 22, Mercury from December 12 through early January, Venus from December 1 - 25, and Mars from November 5 - December 16. That is a VERY EXCESSIVE showing of ENTHUSIASTIC FIRE!!

The heavens are ablaze with firelight this season! With the Sun, Mercury, Venus, and Mars all gathering in Sagittarius, the cosmos invites us to dream bigger, reach farther, and live louder. This is an exceptionally fiery lineup—one that fuels courage, creativity, and conviction. Sagittarius energy is the spark that says “why not?” when others hesitate, the adventurous optimism that propels us toward new horizons. When so many personal planets unite here, we’re being encouraged to break free from old limits, rediscover our sense of purpose, and trust the guidance of inspiration.

Mars ignites motivation and forward movement, while Venus adds warmth, charm, and serendipity. The Sun’s passage lights the path of renewal, encouraging us to share our truth and expand our worldview. And with Mercury joining in, words, ideas, and insights flow fast—just be mindful of overstimulation or burnout from too many “yes’s.”

This much fire can be exhilarating, but it also asks for grounding. Let enthusiasm be your compass, but remember that the brightest flames sustain their light through steady fuel—faith, focus, and a deep trust in the journey ahead.

5. Capricorn takes over mid-month!

The Sagittarius fire party has been raging since November. As December rolls on, more level-headed, strategy-driven Capricorn starts to take the reigns. Preparations for wrapping up 2025 and launching the 2026 you hope to create will be buoyed by the Sun in Capricorn from December 22 - January 22, Venus in Capricorn starting around December 25, and Mars making its move into Cap December 16. Mercury will join the Cap party in January.

As Sagittarius season fades into the distance, the wild flames of inspiration begin to condense into the glowing embers of focus and form. This is the natural alchemy between fire and earth—the visionary spark of Sagittarius giving way to Capricorn’s disciplined structure. Where Sagittarius says “yes” to every possibility, Capricorn asks, “which possibilities are best to focus on” and “how will we make materialize passion into form?” The transition between these signs brings a shift from exploration to execution, from adventure to achievement. It’s an ideal time to crystallize ideas born in November and early December into tangible plans with real-world traction.

Capricorn energy is steady, strategic, and masterful at building something lasting. While Sagittarius gives us the courage to dream big, Capricorn provides the blueprint and endurance to climb the mountain. As the Sun, Venus, and Mars gather here, determination and maturity replace distraction and excess. Venus helps us align our ambitions with authentic values and relationships that stand the test of time, while Mars in Capricorn channels effort into efficiency—getting results through steady, intelligent action rather than scattered striving.

This energy invites us to end the year with intention and begin the next with momentum. Make concrete lists, set measurable goals, and commit to consistent progress. Capricorn rewards persistence and integrity, so don’t be afraid to start small but solid. Every brick laid now strengthens the foundation for your 2026 success story. By honoring Capricorn’s practical wisdom, you turn inspiration into manifestation—transforming bright Sagittarius visions into real-world victories that last far beyond the New Year.

6. Still a dash of Scorpio for the first part of the month as Mercury having retrograded back into Scorpio will finish out its extended transit. 

Four of our mega sweet aspects this month come from this movement of Mercury lingering here.

Probing communication, deep research, collaboration, important financial or intimate discussions, are all greatly favored through December 11.

Here are some very notable dates to look out for as aspects occur on these days. The days may be staggered in different time zones and all of the aspects last longer than just the day they are on so look out for manifestations BEFORE and AFTER the aspect dates. 

Note, if a date is listed more than once for a sweet or salty, that is because there are MULTIPLE aspects that day!

SWEET ~ Wonderful boosts are more likely on or around these days: 2, 5, 6, 7, 11, 13, 14, 18, and 27.

SALTY ~ Drama or stress are more likely in the days around: 4, 7, 8, 10, 13, 14, 14, 16, 18, 19, 20, 20-21, 21, 22-23, 23-24, 27, 29-30, and 31.

Notable Moon Dates:

December 4 ~ Full Moon at 13° of Gemini SUPERMOON! 

A full Supermoon in Gemini (the third month in a row with full Supermoons!) heightens mental activity, communication, and curiosity. Emotions may swirl through words, thoughts, and conversations—what’s been unspoken could finally find its voice. This lunation reveals truths in dialogue, clarity through chaos, and new understanding through connection. Expect insights around information, community, or how you share your ideas with the world. Because Gemini energy is light yet restless, it can bring overstimulation or scattered focus if not channeled intentionally.

Best use: let curiosity lead you to insight, but balance mental movement with quiet reflection. Write, talk, brainstorm, or journal to process what’s coming to light. This moon supports breakthroughs in learning, perspective, and honest expression—especially if you listen as much as you speak.

You can see more ways to maximize the potentials through my blog, Powerful Full Moon in Gemini Reveal & Release Ceremony.

December 19 ~ New Moon at 28° of Sagittarius

The new moon in Sagittarius marks a cosmic fresh start filled with hope, adventure, and vision. After months of refining and releasing, this lunation reignites faith in the bigger picture. It opens doors to new journeys—literal or symbolic—and reminds us that growth often begins with a leap of belief. The atmosphere is expansive, optimistic, and ready to seed something meaningful that stretches beyond comfort zones.

Best use: Set intentions tied to exploration, education, and freedom. Dream boldly, make travel or learning plans, and align goals with your truest ideals. Plant the seeds of purpose now, and let enthusiasm and trust guide your next great chapter.

ASPECTS TO BE EXTRA CAREFUL & AWAREFUL:

Salty Summary:

We have a whopping 18 salty aspects this month! One saving grace is that we have a TON of Sagittarius energy, bringing upliftment, expansive curiosity, positivity, solution-oriented thinking, and in general looking at the glass as it is half full (not half empty!). I LOVE this coinciding with a month like this because it will be helpful in taking the bumps that come with a rosy perspective and an attitude that will help to make lemonade from any lemons that show up.

Here are some highlights and see the salty dates above for the complete list of aspect dates:

We have 8 Squares this month. Squares bring tension, but can also be VERY productive. They can be where the rubber meets the road in a situation where resistance is exactly what is needed to activate the push it takes to get through into the next and best version of the possibilities. Like the rise and fall of emotion, the Square has a building process where it hits the pinnacle of tension, and then breaks. Observe this process occurring throughout the month as the issue is presented, it builds, then cracks. Paying attention to this flow can help you forevermore understand the energetic experience of Squares.

Here are the dates of the Squares this month and know that their influence is days BEFORE AND AFTER these dates. You will see the pattern of Mars, Sun, Mercury and Venus in Sagittarius all making Squares with Saturn and Neptune, both in Pisces. The clash of Fire and Water. Action and Emotion. Expansion and Contraction. Faith and Fear.

December 8 ~ Mars in Sagittarius Square Saturn in Pisces

This aspect highlights the friction between boundless enthusiasm and realistic pacing. Mars in Sagittarius wants freedom, adventure, and quick results, while Saturn in Pisces quietly insists on patience, compassion, and proper boundaries. The clash can feel like hitting an invisible wall—plans stall or motivation wavers. But this tension serves a purpose: it teaches disciplined movement rather than impulsive leaps. The key is persistence with flexibility. Use this energy to identify weak points in your plans and strengthen them through focus and humility. Long-term success comes through steady effort guided by inspiration, not force.

December 14 ~ Mars in Sagittarius Square Neptune in Pisces

This transit blurs the line between motivation and confusion. Mars wants to act boldly, but Neptune casts a dreamy haze that can make goals feel unclear or energy scattered. You may feel tired, uncertain, or idealistic to the point of distraction. However, this alignment also opens spiritual and creative channels—just not the best for hard deadlines. Avoid overcommitting or chasing illusions; instead, align your actions with intuition and higher purpose. Move gently and let inspiration—not pressure—guide your steps. Clarity will return once the mist lifts, and what remains will be more soulful and true to your deeper calling.

December 16 ~ Sun in Sagittarius Square Saturn in Pisces

The Sun square Saturn marks a sobering checkpoint in the Sagittarius adventure. Optimism meets realism; enthusiasm faces accountability. This is where big visions must stand up to the test of structure and follow-through. If delays or doubts arise, don’t see them as failure—see them as invitations to mature your plans. Saturn demands integrity, patience, and a grounded sense of purpose. Prioritize what’s sustainable rather than what’s flashy. If you channel this energy wisely, it can help solidify long-term growth by adding discipline to inspiration, creating something strong enough to last beyond this season’s momentum.

December 20 ~ Sun in Sagittarius Square Neptune in Pisces

This square brings both enchantment and fog. The Sun in Sagittarius radiates truth and optimism, while Neptune in Pisces dissolves certainty into imagination. It’s easy to lose focus or idealize situations under this transit, but it’s also ripe for mystical awareness and creative flow. Guard against deception—self or external—and avoid making irreversible choices. Instead, lean into intuition, meditation, art, and spiritual renewal. Allow inspiration to wash over you without needing to define it yet. This transit reminds us that truth is not always factual—it’s also felt, dreamed, and discovered in moments of surrender.

December 20–21 ~ Venus in Sagittarius Square Saturn in Pisces

Venus meeting Saturn through tension can temporarily cool warmth in relationships or finances. Commitments and boundaries take center stage—this is where love and values are tested for durability. The Sagittarius fire seeks openness, while Saturn in Pisces needs emotional safety and trust. If something feels heavy, it’s asking for maturity, not withdrawal. Clarity and responsibility can deepen bonds that are meant to last. Financially, this is a moment to simplify and plan carefully rather than spend impulsively. Emotional rewards come later—but they’ll be richer for the honesty and effort you put in now.

December 21 ~ Jupiter in Cancer Square Chiron in Aries(Lots more on this one later in this report!) VERY long-lasting influence!

This long-lasting influence expands deep emotional healing. Jupiter in Cancer amplifies nurturing instincts, while Chiron in Aries exposes old wounds around independence, courage, and self-trust. Together, they can stir growing pains—moments where vulnerability and self-protection collide. Yet this is a profoundly restorative aspect for rewriting your story about worthiness and belonging. Healing happens through emotional generosity: allowing care in, offering it to others, and forgiving yourself for past defensiveness. The more you tend to your inner child, the more confident and whole you become. This transit supports lasting breakthroughs in self-compassion and empowered authenticity.

December 23–24 ~ Venus in Sagittarius Square Neptune in Pisces

This dreamy alignment blurs boundaries in love, art, and perception. Venus in Sagittarius wants adventure and truth, while Neptune in Pisces weaves fantasy and idealism. It’s easy to see people or situations through rose-colored glasses now, so pause before leaping into romantic or financial promises. Still, this is exquisite for imagination, beauty, and spiritual connection. Let it inspire creative work, heart-opening experiences, or acts of compassion—just keep one foot in reality. When handled consciously, this transit can remind us that the highest form of love is both inspired and grounded in truth.

December 29–30 ~ Mercury in Sagittarius Square Saturn in Pisces

This aspect challenges communication and confidence in thinking. Mercury in Sagittarius wants to speak boldly and share big ideas, but Saturn in Pisces adds hesitation or self-doubt. Conversations may feel heavy, or plans hit bureaucratic or emotional snags. Take time to listen, edit, and clarify. This is a test of mental maturity—how well you can translate vision into structured words. Rather than pushing through resistance, refine your message, tighten your focus, and commit to honesty over idealism. By early January, what felt like a block will reveal itself as a crucial refinement of your plans.

Of all the aspects this month, the longest lasting and the most profound effects will likely come from the one on October 23, Jupiter in Cancer Square Chiron in Aries. This is because it is between two OUTER planets, whereas the others are between one inner planet and one outer planet, which are shorter in duration and intensity.

While the official aspect happens on October 23, the influence of this connection gets strong in the middle of September and will be VERY STRONG ALL of OCTOBER, NOVEMBER, DECEMBER, and beyond!

Jupiter in Cancer square Chiron in Aries is a long-lasting aspect that blends expansion, healing, and vulnerability in a way that invites deep personal growth. Jupiter in Cancer amplifies themes of emotional security, family, belonging, and the desire to nurture. Chiron in Aries exposes wounds around identity, independence, and the courage to assert oneself. The square creates tension between caring for others and standing fully in your own power.

On the high side, this aspect can bring profound healing in family dynamics, self-confidence, and emotional resilience. It encourages you to grow beyond old patterns, reclaim your voice, and blend compassion with self-assertion. Insights gained now can ripple out to improve both personal relationships and your sense of inner stability.

Pitfalls may include overprotectiveness, emotional overextension, or reacting defensively when old identity wounds are triggered. The square can make it easy to retreat into comfort zones or, conversely, to push too hard for independence in a way that alienates support.

To make lemonade from any lemons, consciously work on integrating self-nurturing with self-leadership. Practice setting boundaries without guilt, and approach discomfort as a guide to deeper healing. The slow, steady nature of this transit allows you to build lasting strength from the inside out.

MY TOP FAVE ASPECTS OF DECEMBER 2025:

Remember that you can experience the good vibes BEFORE and AFTER the dates listed as the web of influence extends beyond the day of exact connection.

December 11 ~ Mercury in Scorpio Trine Neptune in Pisces

Logic and intuition blend beautifully under this poetic aspect. Communication takes on a soulful tone, with imagination and empathy leading the way. It’s easier to express feelings through art, storytelling, or spiritual reflection. The veil between thought and feeling thins—listen to what your dreams or instincts whisper.

December 18 ~ Venus in Sagittarius Trine Chiron in Aries

Love and healing walk hand in hand. Venus softens Chiron’s lessons, opening the heart to freedom, forgiveness, and renewed trust. Relationships deepen when honesty replaces armor. Self-worth strengthens when you celebrate your individuality instead of hiding it. This is love as liberation, not limitation.

Best use: Express affection openly, mend a misunderstanding, or indulge in what makes you feel vibrant and authentic.

December 27 ~ Mercury in Sagittarius Trine Chiron in Aries

Words become medicine. This gentle fire trine encourages healing through communication, humor, and perspective. Conversations that once felt hard now bring release and understanding. It’s a chance to speak from confidence, not defense, and to share wisdom gained from your personal journey.

Best use: Say what needs saying with warmth and courage. Write, teach, or inspire others through the lessons you’ve lived.

****The most influential aspect that is exact this month but has been in effect at least since MAY, every month, and will continue to be in close proximity for the rest of 2025 and beyond is:

Uranus in Taurus Sextile Neptune in Pisces ~ A Long-Term Portal of Change

This connection is still in effect EVEN when Uranus is in Gemini and Neptune is in Aries! They have been dancing together in harmony for a while and we have this glorious connection to look forward to for a while more. 

One of the most important background influences of this extended time is Uranus in Taurus making a supportive sextile to Neptune in Pisces. This is not a fleeting alignment—it will be in effect for more than half of 2025 and beyond, with effects , steadily shaping the undercurrents of our lives and the collective story. Because it lingers, it doesn’t always feel like a sudden event, but its influence is profound, expanding, and amplifying over time.

Uranus in Taurus pushes innovation in how we live, earn, and relate to the material world. It sparks breakthroughs in technology, sustainability, and resources, urging us to find new ways to anchor security in a rapidly shifting landscape. Meanwhile, Neptune in Pisces dissolves boundaries, heightening spiritual awareness, compassion, and imagination. It softens the edges of reality, allowing intuition and inspiration to guide us into uncharted territory.

When Uranus moves into Gemini and Neptune into Aries, the sextile continues but the dance changes tone. The focus shifts from grounding vision into form toward igniting ideas and pioneering action. Uranus in Gemini electrifies communication, learning, and connection, sparking breakthroughs in technology, media, and how we share truth. Neptune in Aries infuses spirituality with courage and urgency, calling for bold, inspired action. Together, they amplify visionary leadership, collective awakening, and innovative movements that rewrite cultural narratives. This next phase carries a faster, more fiery tempo—where inspiration demands expression, and ideas spark revolutions in real time.

When these two giants work in harmony through a sextile, fresh possibilities emerge at the intersection of the practical and the mystical. Dreams can take form in tangible ways; visions once only imagined may find grounding in reality. This aspect invites us to weave creativity into daily life, to allow spiritual ideals to influence material choices, and to channel innovation toward compassion and unity.

On a personal level, this rare connection offers a bridge between inspiration and innovation. You can use it by noticing where imagination is stirring and then grounding those insights into practical, sustainable steps. Meditate or journal to access Neptune’s visions, then let Uranus inspire creative solutions and fresh approaches. This is a chance to align spiritual ideals with daily choices, weaving intuition into action and steadily building a life infused with meaning and originality.

Because this influence spans a long time, the best use is steady, mindful engagement. Notice where your imagination is asking to be anchored and where practical changes can open space for soulful living. Collective shifts in art, healing, spirituality, and eco-conscious technologies are likely to accelerate under this influence. Individually, this is a time to embrace breakthroughs that feel both inspired and sustainable.

This long-term alignment is a reminder that lasting change doesn’t have to be forced. By opening to inspiration and grounding it in steady action, we can create lives—and a world—that reflect both vision and vitality.
