Weekly Astrology Update: December 15 - 21, 2025
Overview
Week of December 15 – 21, 2025:
The week opens with Mars entering Capricorn and closes with the Sun entering Capricorn, bringing a stronger focus on structure, responsibility and long-term goals. Earth element emphasis increases as Mars and the Sun join Uranus in Taurus, highlighting the influence of Earth signs and encouraging practicality, realism and steady progress after a period with little grounding.
Mercury completes its post-shadow phase on December 17, helping plans, conversations and decisions finally move forward with greater clarity, following Neptune’s recent station direct.
The Sun in Sagittarius squares Saturn and later Neptune in Pisces, highlighting pressure between duties, limits and fading motivation, followed by uncertainty or low energy that calls for rest and realistic expectations. Venus square Saturn can test relationships or self-worth, asking for maturity and commitment rather than avoidance.
Saturn and Neptune continue moving forward through the final degrees of Pisces, closing a long chapter shaped by dissolution and the blurring of old structures. Neptune moves through the very last degree of the zodiac (29° Pisces), emphasizing endings, release and the completion of a collective cycle before both enter Aries and conjoin on February 20, 2026.
Jupiter, Uranus and Chiron remain retrograde, slowing outward momentum and emphasizing review, recalibration and unfinished collective themes.
The Moon moves through Scorpio, Sagittarius and Capricorn.
A New Moon at 28° Sagittarius on December 20, 2025, opens space for renewed vision, honesty and a reassessment of beliefs before the Capricorn season begins.
December 21 marks the Solstice, a turning point of light and a shift in the seasonal cycle.
Happy birthday to all Capricorns.
