January 2027 Astrology Calendar: Every Transit, Date and Time

January 2027 begins the year with a clear start date and a clear brake. The Capricorn New Moon on January 7 favours setting goals; three days later Mars turns retrograde for almost three months. Venus and the Sun move into lighter, more social signs, and two slow outer-planet aspects shape the background. All times below are UTC, calculated with the Swiss Ephemeris; the table above converts them to your local time.

The big picture for January 2027

Mars retrograde is the theme of the season. Mars stations at 10°25′ Virgo on January 10, moves backward through Virgo, re-enters Leo on February 21 and turns direct on April 1. Projects, conflicts and physical routines from autumn come back for revision. Starting new battles or forcing results tends to cost more energy than usual during these months.

The other side of January is social and forward-looking. Venus enters Sagittarius on January 7, Mercury enters Aquarius on January 13 and the Sun on January 20. Mercury and the Sun both meet Pluto at around 5° Aquarius, and Uranus makes an exact sextile to Neptune on January 15. Jupiter remains retrograde in Leo all month.

Week by week

January 1–9: superior conjunction and the Capricorn New Moon

The year opens with the Sun conjunct Mercury on January 1 at 11°02′ Capricorn. This superior conjunction starts a new Mercury cycle and suits clear, practical planning. Venus squares Jupiter on January 3, a warning against overspending after the holidays.

The New Moon on January 7 at 20:24 UTC falls at 17°18′ Capricorn: the best date this month for yearly goals, career plans and long-term commitments. Venus enters Sagittarius the same morning, then trines Neptune and opposes Uranus on January 9. Expect a pull toward freedom, travel and spontaneous plans in relationships.

January 10–16: Mars turns retrograde

Mars stations retrograde on January 10 at 12:59 UTC at 10°25′ Virgo. Stations feel heavy and slow; avoid scheduling surgery, major purchases of machinery or confrontational meetings right on this day if you can. Venus sextiles Pluto on January 11.

Mercury enters Aquarius on January 13, sextiles Neptune and trines Uranus on January 14: a strong two days for ideas, technology and networking. On January 15 Uranus sextiles Neptune at about 2° Gemini and Aries, the rare outer-planet aspect of the month. Venus trines Saturn that evening, which steadies relationships and agreements. Mercury conjoins Pluto on January 16 at 4°48′ Aquarius, good for research and serious conversations; Venus squares retrograde Mars the same day, so old relationship tensions may resurface.

January 17–23: Aquarius season and the Leo Full Moon

Mercury sextiles Saturn on January 18. The Sun enters Aquarius on January 20 at 07:30 UTC and Aquarius season begins. On January 22 the Sun trines Uranus and sextiles Neptune, and the Full Moon follows at 12:17 UTC at 2°14′ Leo. It highlights creativity, romance, children and self-expression, with retrograde Jupiter in Leo asking you to look honestly at what you want recognition for.

January 24–31: Sun meets Pluto, Mercury enters its shadow

Mercury sextiles Venus on January 23. The Sun conjoins Pluto on January 25 at 08:01 UTC at 5°06′ Aquarius, a day of intensity and power questions in groups, work and technology. Around January 25–26 Mercury passes 20°55′ Aquarius and enters the shadow of the February retrograde. Mercury opposes Jupiter on January 27 and Venus trines Jupiter on January 29, the warmest aspect of the month for love and generosity. The Sun sextiles Saturn on January 30, a good closing note for practical plans.

How to use the January calendar

1. Set your yearly goals at the Capricorn New Moon on January 7, before Mars turns retrograde.
2. Treat Mars retrograde as a revision period. Return to unfinished projects, repair routines and train for endurance rather than personal records.
3. Use January 14–16 for ideas and research, when Mercury links with Uranus, Neptune and Pluto.
4. Expect old tensions around January 16, when Venus squares retrograde Mars, and answer them calmly.
5. Finish contracts and important messages before mid-February, because Mercury enters its shadow around January 25.
