By If it feels like you’re on the precipice of a whole new era, it’s not just you — it’s that the astrology of the moment is truly extraordinary. Neptune, the planet of dreams, mysticism and spirituality, takes approximately 165 years to orbit the sun and make its way through the zodiac, and for the first time since the late 1800s, it’s entering Aries, the impulsive, competitive, action-oriented fire sign. From Sunday, March 30 to Wednesday, October 22, 2025 — and then from early 2026 until 2039 — Neptune will make its way through astrological territory never before charted during our lifetimes, bringing a more initiative-taking, independent and assertive tone to the way in which we idealize, dream and engage with imaginative and spiritual pursuits. Here’s what to know to make the most of what’s sure to be an eye-opening and wild ride.
What is the meaning of Neptune in Aries?
Neptune, the planet that oversees dreams and spirituality, tends to cloud rational thought and encourage you to put on rose-colored glasses. Think of a particularly stressful situation at work or ongoing emotional challenge you’ve faced in a relationship. Neptune’s the planet that helps you to lean into idealism — sometimes escapism — in order to smooth over the rough edges of reality, telling yourself that with a little extra time, effort or TLC, everything’s going to be OK. It fuels romanticism and supports self-healing and compassion for others. Since 2011, Neptune has been in Pisces, the mutable water sign, which it also happens to rule and, therefore is right at home in. The energies of the sign of the Fish and Neptune not only complement but inform one another.
But in Aries, ruled by Mars, the planet of action, Neptune’s presented with a thoroughly different ball game. Instead of a more passive, dreamy, compassionate approach to making your dreams a reality, you could be inspired to be more trailblazing, pioneering, action-oriented and assertive or even aggressive. Because Aries is associated with the first house of self, this period also lends itself to doing self-work and caring for your psychological well-being in a way that will bolster your confidence, self-image and ability to go to bat for your boldest goals.
Because Neptune is an outer, transpersonal planet, its effects tend to be felt on a societal level more than a day-to-day, personal one (unless it’s hitting your birth chart spot-on). And for a sense of what its transit through Aries could bring, consider the fact that the last time it entered Aries was April 13, 1861 — one day after the attack on Fort Sumter, which ushered in the American Civil War. The US clashed (Aries) over what the country’s collective dream (Neptune) ought to be. And until 1875, when Neptune finally left Aries for Taurus, the world was immersed in a rapid-fire technological evolution marked by the introduction of numerous modern inventions, like the typewriter, telephone and phonograph.
When will Neptune be in Aries?
On Sunday, March 30, at 8 a.m. ET/5 a.m. PT, Neptune enters Aries, and it’ll move forward in the dynamic fire sign until its retrograde begins on Friday, July 4. It re-enters Pisces on Wednesday, October 22, where it’ll remain until January 26, 2026, when it moves back into Aries and stays there until March 2039.
Along the way, Saturn, the planet of boundaries, limitations and industrious work, will also enter Aries on May 24, where it remains until it retrogrades back into Pisces on September 1. As the taskmaster planet makes its way through the cardinal fire sign this year, you could notice a surge of go-getter, self-focused energy that inspires you to take a more dynamic, initiative-taking approach to put your nose to the grindstone, claiming responsibility, stepping into positions of authority and laying the groundwork for pursuing your most ambitious goals.
