December shimmers with that familiar end-of-year magic, and the illuminations across Tokyo make the city glow as we take stock of who we’ve become in the past year. We’re leaving behind the emotional heaviness of retrograde season, and the air feels sharper, as though the world is encouraging us to take a deep breath before we cross the threshold into a new solar year. The calendar makes it easy to look back, but we’re still in adventurous Sagittarius season — this is a time to not just reflect but expand, to imagine the best possible version of ourselves we’re growing into.
We begin the month with a full moon in Gemini on December 4. Bottled up emotions or thoughts might come bubbling to the surface on this day; when in doubt, compassionate honesty won’t lead you astray. Then, Neptune, our dreamy planet of spirituality and illusions, stations direct on December 10 after a five-month retrograde. This transit will help clear up confusing inner turmoils and allow us to put the deep inner work we’ve done into action. This is just in time for Mercury entering expansive Sagittarius, which takes place the day after, giving us the courage to speak honestly and envision bigger, brighter futures.
Mars moves into Capricorn on December 15, grounding our ambitions with newfound focus. (Plus, it will help you come up with beautifully coordinated to-do lists for all your pre-holiday preparations.) The new moon in Sagittarius on December 19 beckons in a wave of fresh optimism, whether it’s noticing a new path or experiencing a reignited dream. Then, on December 21, we enter ambitious Capricorn season, marking the winter solstice and a general turn toward steadiness and structure in our daily lives. Venus also finds its home in Capricorn on Christmas Eve, blessing us with a renewed sense of commitment towards the people we cherish and a feeling of patient, enduring love.
December is a month that wants you to feel both the weight of everything you’ve survived this year and the possibility of all that’s to come. Go gently, go bravely — you’re stepping into a new chapter with more wisdom than you give yourself credit for.
Keep reading for your sign’s December horoscope, and don’t forget to check both your sun and rising signs.
