Neptune in Aries: dates, meaning and what it means for your sign
Neptune in Aries is one of the slow transits that set the tone for years. This guide gives the exact dates Neptune enters and leaves Aries, what astrologers read into it, the retrogrades that happen inside it and the area of life it touches for each sign.
Neptune is in Aries from March 30, 2025 to March 23, 2039, with short returns to the neighbouring signs at both ends; the unbroken stay runs from January 26, 2026 to May 22, 2038. Astrologers read it as new ideals about identity, courage and fresh starts, with a risk of illusion.

| Mar 30, 2025 | Oct 22, 2025 | Neptune enters Aries; then backs into Pisces while retrograde |
| Jan 26, 2026 | May 22, 2038 | Returns to Aries, moving forward; then moves on into Taurus |
| Oct 21, 2038 | Mar 23, 2039 | Backs into Aries while retrograde; then moves on into Taurus |

When is Neptune in Aries?
Neptune is in Aries from March 30, 2025 to March 23, 2039, with short returns to the neighbouring signs at both ends; the unbroken stay runs from January 26, 2026 to May 22, 2038. A slow planet often enters a sign, backs out of it while retrograde and then returns to stay; that is why there is more than one date. After that Neptune is in Taurus from March 23, 2039.
What Neptune in Aries means
Neptune stands for dreams, ideals, imagination and illusion; Aries stands for the self, courage and beginnings. Astrologers read a long period of new ideals about identity and action: inspiration to begin again, causes worth fighting for, and the risk of confusing the fantasy of a fresh start with a real one.
Who notices it most. People with the Sun, Moon, rising sign or personal planets in Aries, and in Cancer, Libra and Capricorn, which Neptune squares or opposes from Aries. Everyone else can read it through the house it falls in, below.
What to do
Give a dream its first concrete step. Check a crusade against the facts. Keep a creative or contemplative practice going. The sky suggests; you decide.
