September Cosmic Calendar

 

September 1st: Saturn re-enters Pisces ~ 4:06am EST
On Monday, September 1st, we begin the month with Saturn retrograding back into Pisces at 4:06am EST. Saturn first entered Aries in May of this year, but now returns to Pisces to finish out this chapter, where it will remain until February. In Pisces, Saturn asks us to bring grounding and structure to our dreams, visions, and fantasies. Think back to the period from March 2023 through May 2025. You may have found your aspirations to be expansive, even overwhelming at times, and perhaps struggled with how to make them tangible. Progress often required careful preparation, discipline, and steady effort. Emotional healing was also a key theme, and for those unwilling to face what needed mending, things may have unraveled or revealed deeper challenges.

During this final five-month stretch of Saturn in Pisces, we are invited to revisit these lessons with greater clarity. It is time to balance the boundless, imaginative energy of Pisces with Saturn’s call for practicality and sustainability. Notice where cycles are wrapping up, where illusions are dissolving, and where you’re ready to bring vision into form. Trust Saturn to help you refine, ground, and make real what once seemed just out of reach.

September 2nd: Mercury enters Virgo ~ 9:23am EST
On Tuesday, September 2nd, Mercury enters Virgo at 9:23am EST. Mercury is at home in this sign, one of the two it rules, and will remain here until September 18th. Because Mercury governs the mind, logic, communication, and perception, its placement in Virgo supports sharp focus, analytical thinking, and careful attention to detail. This is an excellent two week period for problem-solving, organizing, streamlining routines, and bringing order to the areas of life that feel cluttered or inefficient. Clear, concise communication also comes more naturally under this influence, making it easier to work on projects that require precision and thoroughness.

The potential challenges of this transit include overthinking, being overly critical of ourselves or others, and struggling to switch gears or multitask. Those with natal Mercury in Taurus, Cancer, Virgo, Scorpio, or Capricorn often feel most at ease with this energy and may find it highly supportive. For Mercury in Aries, Leo, Libra, or Aquarius, the influence is more neutral, neither particularly helpful nor disruptive. If your natal Mercury is in Gemini, Sagittarius, or Pisces, however, the meticulous and exacting nature of Mercury in Virgo can feel restrictive or nitpicky, requiring a conscious effort to balance detail-oriented focus with broader, more flexible thinking.

September 3rd: Mercury square Uranus ~ 3:40am EST // Jupiter trine North Node ~ 2:36pm EST 
On Wednesday, September 3rd, two major transits take place. The first arrives early in the morning, at 3:40am EST, when Mercury squares Uranus. This energy can stir up restlessness, mental overdrive, and an almost nonstop flow of thoughts or chatter. Conversations may run long, or you might find yourself rambling without a clear point. Others may surprise you with their words or behavior, catching you off guard. This is a day when the mind can easily get stuck in loops of “what ifs,” so it’s important to stay grounded in the present and give yourself mental breaks where possible.

Later in the day, at 2:36pm EST, Jupiter forms a trine to the North Node of the Moon. This transit has been building over the past week and will continue to be felt into next week. Jupiter’s expansive influence here supports growth, bold steps forward, and opportunities that feel aligned with our greater path. This is a chance to stretch beyond your comfort zone and step toward experiences that feel exciting, adventurous, and full of potential. Progress comes through courage, by saying yes to what feels both meaningful and inspiring.

September 4th: Mars square Jupiter ~ 10:58pm EST 
On Thursday, September 4th, Mars forms a square with Jupiter at 10:58pm EST, a transit that has been building over the past several days and will linger into early next week. Mars sits at 18 degrees Libra while Jupiter is at 18 degrees Cancer, creating a cardinal square that can feel sticky, impulsive, and restless. This is a daredevil aspect, often fueling bold but reckless choices, leaping before looking, or saying yes to more than you can realistically handle.

The energy may push us toward impatience, overextension, and a restless drive for action. While taking initiative can feel like a release valve, it’s important to pause and consider the consequences before charging ahead. This transit encourages adventure and exploration, but discernment matters. There’s a difference between crossing the street toward new horizons and darting into traffic without looking.

September 6th: Uranus Rx begins ~ 12:51am EST 
On Saturday, September 6th, Uranus stations retrograde at 12:51am EST, beginning a cycle that lasts until February 3rd. Uranus moves retrograde every year for about five months, so its rhythm is familiar. but each cycle highlights a different area of growth and change. While Uranus in direct motion often brings sudden shifts and external disruptions, its retrograde phase turns the focus inward, offering space for reflection and gradual, more deliberate transformation.

With Uranus currently in Gemini, this retrograde emphasizes shifts in perspective, self-concept, and communication. You may find yourself rethinking old narratives, reconsidering how you connect with others, or reframing the way you approach learning and information. Rather than rushing into change, this period supports moving slowly, integrating insights, and preparing for breakthroughs at a steadier pace.

At the start of this retrograde, Uranus is stationed at 1 degree Gemini, but it will dip back into Taurus before the cycle ends. This gives the retrograde two distinct phases: from now until November, the focus is on Gemini themes of thought and communication; later, as Uranus returns to Taurus, the energy will shift toward stability, resources, and the material foundations of life.

September 7th: Full Moon in Pisces / Lunar Eclipse ~ 2:08pm EST 
On Sunday, September 7th, the Full Moon in Pisces occurs at 2:08pm EST, with the Moon at 15 degrees Pisces and the Sun at 15 degrees Virgo. Falling exactly halfway through their respective signs, this lunation also arrives as a total Lunar Eclipse. This will be most potent in Asia and western Australia, where the visibility will be the greatest. This is the opening of eclipse season, which continues until September 22nd. Eclipse season is always a powerful period, when the veil is said to thin and transformation accelerates. Changes often come with urgency or pressure, especially around the eclipses themselves on September 7th and 21st.

This particular Full Moon is deeply emotional, sensitive, and dreamlike. Imagination runs strong, but illusions may be pierced by reality, bringing clarity where we’ve been avoiding truth. Emotions are heightened, and the energy can swing from waves of longing and daydreaming to intense bursts of creativity and insight. With the Moon in the second decan of Pisces (ruled by the Moon itself), intuition and spirituality are emphasized. This is a time to trust signs, synchronicities, and gut feelings, while also remembering to stay grounded.

The Virgo Sun reminds us not to get lost in fantasy or overwhelm, but to keep one foot firmly on the earth. Simplicity, discernment, and clarity are allies here, helping us anchor the wisdom of this eclipse into tangible growth.

September 10th: Sun conjunct South Node ~ 3:19pm EST 
After a few quieter astrological days, the Sun meets the South Node on Wednesday, September 10th, perfecting at 3:19pm EST. The South Node is a point along the Moon’s orbital axis that represents history, memory, and karmic ties. This transit, felt throughout the day, draws us toward nostalgia and the familiar, whether childhood memories, old favorites, or even echoes of past lives.

You may find yourself craving comfort, revisiting beloved music, films, or places that once brought joy. The energy can feel like a warm blanket, reminding us of where we’ve come from and the experiences that have shaped us. While it can be meaningful to reconnect with the past, it’s important not to get stuck there. This alignment is best used as inspiration. Gather insight from what once was, and carry it forward into the present and future with clarity and purpose.

September 11th: Mercury conjunct South Node ~ 9:58pm EST 
On Thursday, September 11th, Mercury aligns with the South Node of the Moon, following the Sun’s connection to this same point just yesterday. This transit invites us to look back, whether through reminiscing with friends and family, revisiting old memories, or rediscovering ideas that once sparked our curiosity. It’s also supportive for recalling forgotten details, finding misplaced objects, or mentally returning to significant moments from the past. This can even be helpful for recalling past lives. The aspect perfects at 9:58pm EST, with its energy especially strong in the hour before and after. Use this time to reconnect with what has shaped you and notice what the past may still have to offer.

September 12th: Sun sextile Jupiter ~ 3:30am EST // Mercury sextile Jupiter ~ 5:53pm EST 
On Friday, September 12th, we’re graced with two cheerful transits. The first arrives early, at 3:30am EST, when the Sun in Virgo forms a supportive sextile to Jupiter in Cancer. This uplifting influence lasts throughout the day, bringing optimism, generosity, and a spirit of adventure. It encourages openness to new experiences and helps us approach challenges with humor and grace, making it easier to see fresh possibilities. Later, at 5:53pm EST, Mercury also sextiles Jupiter, adding another layer of warmth and inspiration. This energy sparks lively conversations, exciting ideas, and plenty of humor. It’s a wonderful influence for sharing thoughts, exploring philosophy, and engaging in meaningful discussions. Writers and creatives, in particular, may find words flowing with ease and enthusiasm.

September 13th: Sun conjunct Mercury ~ 6:51am EST 
On Saturday, September 13th, the Sun meets Mercury at 6:51am EST in what’s known as Mercury Cazimi, a potent alignment often called the “genius aspect.” During the exact window from 5:51am to 7:51am EST, the mind is especially sharp and receptive, with ideas flowing quickly and brilliantly. This energy continues throughout the day, offering perspective shifts, flashes of inspiration, and sudden insights. Some of these ideas may be fleeting, so it’s wise to jot them down or share them aloud before they slip away. With this Cazimi happening in Virgo, spending time in nature can open you further to divine inspiration and help channel clarity into practical form.

September 15th: Venus sextile Mars ~ 11:03pm EST 
On Monday, September 15th, Venus forms a harmonious sextile with Mars at 11:03pm EST. Venus shines at 25 degrees Leo while Mars energizes at 25 degrees Libra, blending fire and air in a lively and creative exchange. This pleasant aspect stirs passion and inspiration, motivating us to direct our energy toward pursuits that light us up. It’s especially supportive of creative expression like music, dance, art, photography, and any form of play that lets us channel joy into action. In relationships, this transit encourages teamwork, passion, and mutual engagement, making it easier to collaborate and connect in meaningful ways. It can also spark healthy competition, offering a boost for athletes, performers, or anyone working together toward a shared goal.

September 16th: Venus trine Chiron ~ 6:10am EST  // Mars opposite Chiron ~ 11:46am EST 
On Tuesday, September 16th, we experience two significant Chiron transits. The first arrives at 6:10am EST, when Venus forms a supportive trine to Chiron. This brings opportunities for healing through relationships, whether by working through old wounds with loved ones or creating an atmosphere where others feel safe and supported. Because this is a trine, the energy flows more easily, suggesting that healing may come in gentle, affirming ways rather than through struggle or conflict.

Later, at 11:46am EST, Mars opposes Chiron. This is a more challenging influence that has been building for several days and will linger through the week. This aspect can stir up frustrations around decision-making, self-assertion, or the tendency to suppress anger, which may then surface as resentment or passive-aggressiveness. It may also manifest physically as tension or discomfort in the body. The invitation here is to lean on the Venus–Chiron trine. Approach vulnerability with openness, communicate honestly, and resist the urge to bottle things up. Releasing what’s inside with compassion can transform frustration into clarity and healing.

September 17th: Mercury opposite Saturn ~ 1:47pm EST 
On Wednesday, September 17th, Mercury opposes Saturn at 1:47pm EST. Mercury sits at 28 degrees Virgo while Saturn, having recently retrograded back into Pisces, also reaches 28 degrees. This transit is strongly felt throughout the day, sharpening the mind and encouraging focused, detail-oriented work. It can, however, tip into over-critical thinking both toward yourself and others, so be mindful and redirect your thoughts when needed. This is an excellent time to tackle projects or work toward a goal, but if you find yourself trying to “fix” things that don’t need fixing, channel that energy into something productive, like helping with tasks that truly need attention or engaging in puzzles or games that challenge your analytical skills.

September 18th: Mercury enters Libra ~ 6:05am EST // Mercury opposite Neptune ~ 6:00pm EST 
On Thursday, September 18th, Mercury moves into Libra at 6:05am EST, where it will remain until October 6th. Mercury in Libra favors fairness, balance, and harmony, making it an excellent time for pleasant conversations, thoughtful discussions, and engaging with art, music, and film. On the flip side, this placement can heighten indecision and make quick, bold choices more challenging. Communication flows best when we seek common ground and aim to unite rather than confront.

Those with natal Mercury in Gemini, Leo, Libra, Sagittarius, or Aquarius will feel especially supported by this energy, finding it enhances self-expression and connection. If your natal Mercury is in Taurus, Virgo, Scorpio, or Pisces, this transit will be more neutral. For those with natal Mercury in Aries, Cancer, or Capricorn, it may require extra effort to compromise and step outside your comfort zone.

Later, at 6:00pm EST, Mercury opposes Neptune, introducing a more dreamy and imaginative influence. This transit can inspire far-reaching ideas, abstract thinking, and creative insights, but it can also blur boundaries and lead to confusion if we’re not careful. Stay grounded while exploring the wilder edges of your imagination, and be mindful of others who may try to drain your energy or offload their problems onto you.

September 19th: Mercury trine Uranus ~ 12:52am EST // Mercury trine Pluto ~ 2:26am EST // Venus enters Virgo ~ 8:39am EST 
On Friday, September 19th, the skies bring us several noteworthy shifts. The first arrives just after midnight, at 12:52am EST, as Mercury in Libra trines Uranus. This airy connection sparks fresh perspectives, innovative thinking, and surprising breakthroughs. Expect flashes of inspiration that help break through stagnation, along with conversations that feel playful, quirky, or delightfully outside the norm.

Shortly after, at 2:26am EST, Mercury also trines Pluto, sharpening focus and adding depth to the day. Where Uranus brings novelty, Pluto cuts through to the essence. This aspect encourages boldness, clarity, and emotional honesty, perfect for meaningful conversations or diving into subjects that matter most.

Later in the morning, Venus enters Virgo at 8:39am EST, where it will remain until October 13th. Venus in Virgo highlights attention to detail, making this an excellent time for refined creative work, artistry that relies on precision, and showing care for others through acts of service. It invites us to consider how we can make the lives of loved ones easier in small but significant ways.

Those with natal Venus in Taurus, Cancer, Virgo, Scorpio, or Capricorn will feel especially supported, finding this transit grounding and creatively enriching. For Venus in Aries, Leo, Libra, or Aquarius, the influence is more neutral, while Venus in Gemini, Sagittarius, or Pisces may find Virgo’s exacting nature a bit restrictive. Regardless of placement, this is a time to learn the value of focus, discernment, and bringing vision into form through practical effort.

September 20th: Venus square Uranus ~ 11:41am EST 
On Saturday, September 20th, Venus forms a square to Uranus at 11:41am EST, an aspect we’ll feel throughout the day. With Venus newly in Virgo and Uranus adding its unpredictable influence, this mutable square can stir up shake-ups in relationships and creativity. Interactions may feel a bit unsteady or surprising. Someone close to us may act in unexpected ways, or dynamics could suddenly shift.

The key is to loosen control and flow with the energy rather than resisting it. While this transit can feel chaotic, it also opens the door to pleasant surprises if we release rigid expectations. In creative work or group projects, differing visions may clash or a partner may take an unforeseen direction, but these twists can also spark innovation. Stay flexible, and you may discover that the disruption leads to something fresh and exciting.

September 21st: Sun opposite Saturn ~ 1:45am EST  // New Moon in Virgo (Black Moon Solar Eclipse) ~ 3:54pm EST
On Sunday, September 21st, we reach the final day of Virgo season, and it arrives with transformative energy. The day begins with the Sun opposing Saturn at 1:45am EST, a sobering influence that may highlight responsibilities, limitations, or the weight of self-criticism. We may long for more freedom or realize that perfectionism has been holding us back. It is time to notice what can be adjusted or released so that greater ease and movement are possible going forward.

Later, the New Moon in Virgo arrives. This is our second Virgo New Moon of the season, and this one is also a Black Moon Solar Eclipse. Visible in Australia, New Zealand, and the Polynesian Islands, this eclipse brings a powerful closing to eclipse season. It is an intensely transformative portal, inviting deep internal shifts. The eclipse opposes both Saturn and Neptune while forming a grand trine with Uranus and Pluto, a rare configuration that amplifies its global significance. These outer planet connections suggest collective change, breakthroughs, and the potential to harness energy for transformation on a larger scale.

While New Moons are inherently inward-focused, this one feels like lighting a lantern within yourself and then contributing that light to the collective flame. The more you tend to your own passion and center yourself, the more your energy can uplift others. Take time for yourself without guilt—this inner renewal is the first step to offering meaningful support to the wider world without depleting your own reserves.

September 22nd: Mars enters Scorpio ~ 3:54am EST // Sun enters Libra ~ 2:19pm EST 
Happy Libra Season! On Monday, September 22nd, the day begins with Mars entering Scorpio at 3:54am EST, where it will remain until November 4th. Mars in Scorpio is intense, exacting, and deeply focused. This placement strengthens our determination, helping us pursue goals with passion and persistence, while also empowering transformation of both mind and body. It fuels intimacy and desire, making it a potent time for deep connections, though it can also bring difficulty with forgiveness and a tendency to hold onto grudges. Transparency is key. Deception is much harder to conceal under this transit.

For those with natal Mars in Cancer, Virgo, Scorpio, Capricorn, or Pisces, this energy will feel especially resonant, bringing vitality and drive. Mars in Aries, Gemini, Libra, or Sagittarius may experience smooth sailing but without a noticeable boost. Meanwhile, Taurus, Leo, and Aquarius placements could feel more fatigued, requiring extra rest and slower, more deliberate action.

Later, at 2:19pm EST, the Sun moves into Libra, officially beginning Libra Season and marking the Autumnal Equinox in the Northern Hemisphere (and the Vernal Equinox in the Southern). The equinox is a sacred moment of balance, when day and night are equal in length. Libra Season, a cardinal air energy, is ideal for engaging with Venusian themes like art, music, design, creativity, and social connection. This season encourages harmony, fairness, and the pursuit of balance, whether in relationships, creative work, or daily life. Enjoy gatherings, lively conversations, and finding common ground rather than stirring conflict.

September 23rd: Sun opposite Neptune ~ 8:53am EST  // Sun trine Uranus ~ 10:55pm EST
On Tuesday, September 23rd, the Sun in Libra opposes Neptune in Aries at 8:53am EST. This transit heightens imagination and opens the door to creative inspiration, allowing abstract ideas and visions to flow more freely. It can feel like slipping on rose-colored glasses and seeing the beauty and potential in people and situations. While this perspective can be uplifting, take care not to overlook red flags or idealize things simply because you want them to be a certain way.

Later in the evening, at 10:55pm EST, the Sun trines Uranus, bringing a fresh wave of spontaneity and excitement. This is an excellent transit for shaking off stagnation, embracing surprises, and embarking on new adventures. The combined energy of the day makes it ideal for a spontaneous outing, trying something outside your usual routine, or simply moving through the world with curiosity and wonder.

September 24th: Sun trine Pluto ~ 2:04am EST // Mars square Pluto ~ 7:51am EST
Wednesday, September 24th carries a distinctly Plutonian tone, bringing depth, intensity, and focus. The day begins with the Sun trining Pluto at 2:04am EST, an empowering influence that lasts well into the day. This transit supports goal-setting, ambition, and personal strength, helping you shed fears and insecurities while stepping boldly into transformation. This is the constructive side of Pluto, the kind that fuels growth, courage, and lasting change.

Later, at 7:51am EST, Mars squares Pluto, a fixed square that has been building for several days and will linger through the week. This is a more volatile energy, one that heightens stubbornness, conflict, and power struggles. Anger and frustration can feel exaggerated, and the impulse to pull the rug out on yourself may be strong. While this can be destructive if left unchecked, it also offers an opportunity to reflect on power dynamics in your life and the world around you. Choose not to feed unhealthy imbalances or destructive impulses and instead direct the intensity into transformation rather than conflict.

With this, we close out the month’s major transits. I’ll be taking a short forecast break until October 1st, though readings are still open for booking. Wishing you a wonderful end to September! May you use the quieter days ahead to rest, reflect, and reset.
