The holidays are enveloped in Jupiterian magic—it’s no coincidence that everything feels a little bigger and brighter. From the festive gatherings to the quiet hope in our hearts of what’s to come in the new year, one thing’s for certain and it’s that Sagittarius season is fueled by hope and wonder. ‘Tis the season to be jolly, (literally) as this mutable season reminds us that life is meant to be lived to the fullest.
On Dec. 19 at exactly 8:43 p.m. ET, the moon will renew itself at 28 degrees of Sagittarius, signaling a powerful reset… but at the edge of this fire sign. The new moon is equivalent to a clean slate, as it marks the beginning of a brand-new lunar cycle. But while every new moon presents an opportunity for renewal, this one is especially bold, fiery and momentous. In a nutshell? The cosmos is calling you to question the stories you’ve been living in (or telling yourself) and decide whether they still feel true.
Governed by larger-than-life Jupiter — the planet of growth, wisdom and faith — which is currently retrograde in the intuitive sign of Cancer, there is a need to go inward and reflect on what you truly long for, rather than to chase external validation. What dream still lives in your body, even if you’ve tried to outgrow it? The essence of Cancer asks us to feel our way toward the truth, and to honor emotional intelligence as sacred wisdom. With Luna activating the Sagittarius area of your chart, this is an invitation to dream bigger and more importantly, to release the beliefs that have been dimming your inner glow. Remember, Sagittarius’ mutable fires are adaptable and endlessly curious, but at 28 degrees, we’re also at a threshold. Old limiting beliefs are starting to crumble as we prepare to carry only what is authentic and true forward.

Still, this lunation isn’t going to let us get swept up in the fantasy—not even close. Luna will form almost an exact square to Saturn and Neptune in Pisces, tension that swings between our hopes and dreams versus our current reality. This is precisely where the wildfire of Sagittarius meets the emotional depth of Pisces. Our dreams will be tested — are your ideals rooted enough to sustain you? Can your faith take shape in the real world?
To add, Luna will be sitting close to Venus in Sagittarius, amplifying relationship themes—love, desire and commitment are up for reflection. This is especially true when considering Venus’ square to Saturn which asks us to take a closer look at our boundaries. Where have you been overly enthusiastic, or giving more than you truly have? Where do you need to temper impulse with self-respect?
Fortunately, Venus’ trine to Chiron offers deeper healing through courage and emotional honesty. Vulnerability becomes a strength here, whether it’s speaking your truth or simply choosing to choose yourself. Now is not the time to play it small or safe. On the contrary, this is a call to trust your inner compass and trust that with a plan your dreams can indeed come true.

Aries
Something about this moment asks you to zoom out and remember the bigger picture, Aries. With the moon renewing itself in your ninth house of belief, meaning, and personal philosophy, you’re being encouraged to reconsider what you stand for and where you’re headed. This goes far beyond travel or plans — it’s about your truth. The square to Saturn and Neptune in Pisces stirs subconscious doubts or emotional fog, especially around trusting your intuition versus needing proof. Let this be a recalibration rather than a shutdown. You don’t need all the answers yet, just an honest direction. New moon affirmation: I trust the wisdom guiding my path forward; I allow my beliefs to evolve without guilt or fear.
Taurus
This lunation goes straight beneath the surface for you, Taurus. With the moon renewing itself in your eighth house of intimacy, shared resources, and emotional bonds, you’re being asked to confront what you’re holding onto out of fear rather than trust. This isn’t just about money or logistics — it’s about vulnerability and power. The square to Saturn and Neptune in Pisces can blur boundaries in friendships or long-term goals, making it harder to tell where you end and others begin. Let this be a moment of emotional honesty instead of self-protection. New moon affirmation: I release fear around vulnerability; I allow myself to navigate emotional depth safely.
Gemini
Relationships take on a mirror-like quality right now, Gemini. With the moon renewing itself in your seventh house of partnerships and commitments, you’re being encouraged to reflect on who you’re walking alongside and why. This is less about labels and more about true alignment. The square to Saturn and Neptune in Pisces could lead to mixed signals or uncertainty around expectations, especially in professional or long-term dynamics. Instead of filling in the gaps with assumptions, ask the questions you’ve been avoiding. New moon affirmation: I welcome honest and aligned partnerships; I communicate my needs with clarity and confidence.
Cancer
Your day-to-day life is asking for a gentle but necessary reset, Cancer. With the moon igniting your dutiful sixth house of routines, work, and well-being, you’re being encouraged to reflect on how your daily choices support your energy. Luna’s square to Saturn and Neptune in Pisces could highlight burnout or unrealistic expectations around productivity or purpose. This is a reminder that devotion doesn’t require self-sacrifice. Small shifts in habits can restore balance faster than you realize. New moon affirmation: I honor my energy through mindful routines; I allow balance to guide my daily life.
Leo
Your joy wants to be taken seriously right now, Leo. With the moon renewing itself in your festive fifth house of creativity, romance and self-expression, you’re being reminded that pleasure is not always a distraction. On the contrary, it’s a compass for your heart’s desires. The square to Saturn and Neptune in Pisces could stir doubts about whether something you love is practical or sustainable. Your inspiration doesn’t need to be justified to be real. New moon affirmation: I allow joy to lead me forward; I let my creative desires bloom without hesitation.
Virgo
This moon is an invitation to go inward, Virgo. With Luna renewing itself in your fourth house of home, family and emotional foundations, you’re encouraged to redefine what security truly means to you. Still, the square to Saturn and Neptune in Pisces can bring emotional uncertainty in close relationships, revealing where boundaries need to be put in place. Let this be about building inner safety rather than fixing external dynamics. New moon affirmation: I have the power to create emotional stability from within; I trust my inner foundation to support me.
Libra
Your perspective is shifting in subtle but meaningful ways, Libra. With the moon renewing itself in your curious third house of communication, learning, and mindset, you’re being encouraged to speak more honestly, both with yourself and others. Luna’s square to Saturn and Neptune in Pisces could blur routines or overwhelm your mental space, making clarity feel out of reach. Slow down your thinking instead of forcing conclusions. The right words will arrive. New moon affirmation: I trust my voice and perspective; I communicate with clarity and intention.
Scorpio
Your sense of worth is recalibrating, Scorpio. With the moon renewing itself in your second house of values, income, and self-esteem, you’re being called to look at what you truly value rather than what you’ve been taught to prioritize. Luna’s square to Saturn and Neptune in Pisces could highlight emotional attachments tied to pleasure or validation, but it’s important for you to let this be a moment of self-love. You deserve security that doesn’t come at the cost of self-trust. New moon affirmation: I honor my worth without compromise; I am creating lasting abundance.
Sagittarius
Happy new moon! This is a personal turning point for you, Sagittarius. With the moon renewing itself in your sign, you’re stepping into a chapter of identity, confidence, and self-expression. However, the square to Saturn and Neptune in Pisces could challenge your sense of direction, especially when it comes to emotional or family-related responsibilities. But instead of questioning yourself, refine your vision. New moon affirmation: I trust myself to begin again; I embody my truth with confidence and courage.
Capricorn
This lunation asks you to pause rather than push, Capricorn. With the moon renewing itself in your 12th house of rest, healing, and subconscious patterns, you’re being encouraged to release what’s been quietly draining you. The square to Saturn and Neptune in Pisces could bring mental fatigue or unspoken worries to the surface. Allow this to be a moment of surrender, as opposed to strategy. New moon affirmation: I release energies and truths that don’t resonate with me; I am attuned to my inner wisdom.
Aquarius
Your future visions are evolving, Aquarius. With the moon renewing itself in your 11th house of community, goals, and aspirations, you’re being called to reassess who and what you’re building toward. While Luna’s square to Saturn and Neptune in Pisces could shed light on expectations around money or personal values within group dynamics, you’re not obligated to do anything you don’t want to do. Your dreams deserve supportive foundations. New moon affirmation: I choose to align with people who share similar values; I trust the power of my visions.
Pisces
Your mission and purpose is coming back into focus, Pisces. With the moon renewing itself in your 10th house of career, reputation, and long-term direction, you’re encouraged to claim your ambitions more boldly. Luna’s square to Saturn and Neptune in your sign, however, could trigger feelings of pressure (or self-doubt) to live up to an ideal. But remember, the growth you seek can see fruition slowly and steadily. Your calling becomes crystal clear when you start to trust yourself. New moon affirmation: I am committed to my soul path; divine timing is always on my side.
