December always marks the transition of Sagittarius to Capricorn, or, more plainly, possibility to actuality. The ruling planet of Capricorn is Saturn, who’s known for hard limits, reality checks, and consequences. This month is characterized not only by three planets entering Capricorn but also by four planets (Mars, the Sun, Venus, and Mercury) squaring Saturn between December 8 and 30. A square aspect describes two planets that are at cross purposes. Square aspects are fricative, challenging, and highly creative. They compel us to take action because we’ve hit a snag, or, what might feel like a road block. It would be very easy to feel demoralized if we’re getting stopped at every turn, but square aspects beg us to be productive instead. Take that “no” and turn it into a lesson that helps you make things better! Saturn’s job is to make sure our dreams can survive the harsh demands of the three-dimensional, material world.
It all starts innocently enough with a full Moon in Gemini on December 4, though we may finally feel the effects of too much information, communication, and unnecessary busyness. On the 11th, Mercury’s re-entrance into Sagittarius pours gasoline on an already wild verbal fire. On the 15th, Mars enters Capricorn to cut through the noise and take effective actions. A new Moon in Sagittarius (square Saturn and Neptune) on December 19 kicks up the confusion between what’s real and what’s fabricated. Luckily, the Sun enters Capricorn (winter solstice) on the 21st to offer grounding. Finally, Venus enters Capricorn on the 24th. Love either turns cold or gets serious, and we’ll all need to reassess our values and budgets in favor of necessities. Think of December as a stern and caring teacher who wants you to be an active participant in the realization of your wishes.
