Just before winter truly begins with the solstice on December 21, 2025, the year’s final New Moon offers a symbolic moment to close out 2025—and, in numerology, a nine-year cycle. As we welcome 2026, we also step toward the next nine-year chapter.

During a New Moon, the Moon sits between Earth and the Sun. Its sunlit side faces the Sun, leaving the side facing Earth in shadow, which makes it appear dark in the sky. This effect will be especially pronounced on December 20, when the New Moon brings the darkest night of the year. Not only will the sky be exceptionally dark due to the absence of moonlight, but it also happens on the eve of the Winter Solstice—the longest night of the year.

Yet within this darkness, there are messages of light. As astrologer Rachel Ruth Tate of Casinos Analyzer tells Vogue, this New Moon represents “a ‘lesson is a blessing’ moment—a reset that pushes us all toward honesty, clarity, evolution, and movement, even if we don’t feel ready.”

Below, we explore the meaning of the last New Moon of 2025 and what it may bring in 2026 for three zodiac signs.

What will the New Moon in Sagittarius on December 20, 2025 bring?

This New Moon invites introspection, helping us to feel and perceive both our environment and ourselves. “It encourages us to set goals and aim high, especially since its ruler, Jupiter, is well-placed in Cancer,” explains Tate. How can we embrace this? “You need to believe in yourself enough to pick up the bow and pull the string.”

“Venus is close to Sagittarius, helping us find courage and choose joy,” Tate adds. “On the other hand, Saturn’s pressure meets Neptune’s fog. This means the New Moon isn’t without challenges, as it’s also under pressure from a Saturn square in Pisces—a stern reminder that obstacles are part of the path to success.” How should we respond? Stay patient and keep faith when doubts arise. “‘Someday’ has to become ‘today,’” says Tate. “Remember, you’ll never feel as ‘ready’ as you think you should be.”

“However, Neptune—a potentially confusing planet—also blurs things while in conjunction with Saturn in Pisces,” she continues. Be careful not to get lost in illusion. “There’s a difference between answering a personal calling and seeking glory.” Self-glorification isn’t encouraged, but self-realization is.

The best advice for this New Moon? “Be honest and move forward with love in your process of becoming, however chaotic and imperfect it may be.”

3 zodiac signs most affected by the New Moon

Cancer: deeper clarity and emotional reset
You tend to feel each lunar phase more intensely, Cancer, because the Moon is your ruler and its cycles align with yours. This New Moon will resonate especially deeply due to Jupiter—the Moon’s ruling planet—currently in your sign. Jupiter went retrograde in Cancer in mid-November, and since then you’ve gained insight into what you truly want. From your beliefs about the universe to how you want to live each day, you’ve been reflecting deeply on your life—and that’s a positive thing. Set clear intentions and do your best.

Sagittarius: endings that pave the way for new beginnings
This New Moon falls in your sign, Sagittarius, which often signals fresh starts. But as some things begin, others must end. It’s natural to grieve what’s closing, and it’s easier to turn the page when you acknowledge and accept the situation with dignity. Your ruling planet, Jupiter, is retrograde in Cancer, encouraging you to accept life’s ups and downs gracefully. Remember: there’s no peak without a valley. Venus conjuncts this Moon, gently reminding you that something beautiful awaits beyond the next hill. Keep moving forward.

Pisces: tension now, relief soon
You’re likely to feel the tension of this lunation, Pisces, with Saturn and Neptune sending challenging squares from your sign.With this added tension comes a sense of heaviness, so be sure to give yourself more space than usual to rest and unwind. Things may feel uncomfortable right now, keeping you from fully enjoying life. But this will pass once Saturn and Neptune move out of your typically gentle and pleasant sign in the first two months of next year. Just hang in there a little longer, Pisces. Soon enough, you’ll be able to enjoy yourself again—I promise.
