Aries September 2027 Horoscope — The Three Dates

September is your working month — routine, method, health — and hands over to partnership on the 23rd. The new moon falls on the 30th, so the month's fresh start lands in the relationship sector rather than the work one, right after the handover.

Aries runs a month at one speed and then wonders where it went. The dates below are useful mainly as brakes.

The three dates that structure September for Aries

Every time below is computed — the solar ingress from the Sun's actual longitude, the lunations from the exact moon–sun conjunction and opposition. Times are UTC, in chronological order.

For the first part of September the Sun sits in Virgo, which is your 6th solar house (work routine and health). On September 23 it hands over to your 7th, and the other person becomes the subject, in partnership or in negotiation.

September 30 — the new moon, in your 7th house

A beginning that involves a second person by definition: a partnership, a contract, a formal ask. It is not a lunation for deciding alone.

The new moon is the darkest point of the lunar month — moon and Sun at the same longitude, so nothing of the moon is lit from where we stand. Astrologically it is a starting line, and starting lines are worth more in the two weeks after the gun than on the day. For Aries in September 2027 that window runs from September 30 to roughly October 15 — it runs past the end of the month.

September 15 — the full moon, in your 12th house

A private ending, often unannounced. You will notice the weight leaving before you notice what it was.

Full moon is the moment the moon reaches 180° from the Sun. The sign it lands in is therefore never a matter of opinion: it is whatever sits opposite the season. In September 2027 the Sun is in Virgo and the moon is therefore in Pisces, your 12th house rather than the 7th the new moon opened. That pairing — you open in the 7th and close in the 12th — is what September actually runs on for you.

September 23 — the handover

The Sun crosses into Libra at 06:01 UTC, moving from your 6th solar house to your 7th. The register of the month changes here: work routine and health gives way to partnership. If September feels like two different months, this is why, and the date is the reason rather than a mood.

September week by week for Aries

The dates above cut the month into windows. Which of your houses is active in each one, and which half of the lunar cycle it sits in, is different for every sign — this is the Aries version.

• September 1–14 — Sun in your 6th house (work routine and health); the moon is building toward full — the half of the cycle for starting and pushing.
• September 15–22 — Sun in your 6th house (work routine and health); the moon is shedding light — the half of the cycle for finishing, cutting and recovering.
• September 23–29 — Sun in your 7th house (partnership); the moon is shedding light — the half of the cycle for finishing, cutting and recovering.
• September 30 — Sun in your 7th house (partnership); the moon is building toward full — the half of the cycle for starting and pushing.

If Aries is your rising sign

Read the same three dates against the same house numbers — but as your real houses rather than solar ones. A whole-sign chart with Aries rising puts Virgo on your 6th house and Libra on your 7th, exactly as above, so the September 30 new moon falls in your 7th and the September 15 full moon in your 12th. That version is considerably more specific than the Sun-sign one, and it costs only your birth time to check.

What this forecast does not claim

You will not find a retrograde window, an eclipse degree or an outer-planet ingress here. We publish a date only when we have computed it, and the three above are the three we computed for this month. The dates above are computed; everything else is interpretation of the house they fall in.

A Sun-sign month is the coarsest useful resolution. Your moon and rising sign change what these same three dates mean, and both come from your birth time. Run the free natal chart calculator to see which real houses these dates land in for you, read how transits work for the mechanism, and the twelve houses for what each one covers. The year as a whole is in the Aries 2027 forecast, and the computed calendar behind every date here is in the 2027 year ahead.
