Aries December 2027 Horoscope — The Three Dates

December widens the frame and then reaches the top of your chart on the 22nd. The year ends where it began, on your professional standing, and the new moon on the 27th opens that sector rather than closing it — a start, not a summary.

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 December 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 December the Sun sits in Sagittarius, which is your 9th solar house (travel, study and belief). On December 22 it hands over to your 10th, and your professional standing moves into the light, whether or not you asked for it.

December 27 — the new moon, in your 10th house

The professional beginning of your year: the application, the announcement, the visible move. Use it while people are still deciding rather than after.

A new moon is the moon–sun conjunction: the moon sits between us and the Sun and shows no lit face. It opens a lunar cycle rather than marking an event, so what matters is the fortnight after it, not the day itself. For Aries in December 2027 that window runs from December 27 to roughly January 12 — it runs past the end of the month.

December 13 — the full moon, in your 3rd house

Something gets said. The conversation you have been drafting either happens or becomes impossible to keep drafting.

A full moon is the opposition — moon opposite Sun — which is why it always falls in the sign opposite the current solar season. In December 2027 the Sun is in Sagittarius and the moon is therefore in Gemini, your 3rd house rather than the 10th the new moon opened. That pairing — you open in the 10th and close in the 3rd — is what December actually runs on for you.

December 22 — the handover

The Sun crosses into Capricorn at 02:42 UTC, moving from your 9th solar house to your 10th. The register of the month changes here: travel, study and belief gives way to career and public role. If December feels like two different months, this is why, and the date is the reason rather than a mood.

December 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.

• December 1–12 — Sun in your 9th house (travel, study and belief); the moon is building toward full — the half of the cycle for starting and pushing.
• December 13–21 — Sun in your 9th house (travel, study and belief); the moon is shedding light — the half of the cycle for finishing, cutting and recovering.
• December 22–26 — Sun in your 10th house (career and public role); the moon is shedding light — the half of the cycle for finishing, cutting and recovering.
• December 27–31 — Sun in your 10th house (career and public role); 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 Sagittarius on your 9th house and Capricorn on your 10th, exactly as above, so the December 27 new moon falls in your 10th and the December 13 full moon in your 3rd. 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

No outer-planet position, retrograde window or eclipse is asserted anywhere on this page. Those need checking against an ephemeris before publication, and a monthly horoscope that guesses at them in order to look complete is worse than one that says only what it computed. The dates above are computed; everything else is interpretation of the house they fall in.

Your Sun sign is a third of the picture — the moon and the rising sign move the whole reading, and both need 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.
