The last new moon of 2025 occurs on the evening of Dec. 19, at the end of Sagittarius season and marks the seasonal transition into winter, which begins on Dec. 21.
At this time, we will start to let go of our old sentiments and transition into new ones. The caveat is that the new moon faces off with Venus in Sagittarius, Saturn in Pisces and Neptune in Pisces.
As a result, we may feel like it is hard to set our goals in motion. Saturn restricts, while Neptune makes us dream. The combination will push us to put more stamina into our manifestations. We must give them time to commence and allow them to adjust accordingly. Our romantic emotions will be tested, urging us to redefine the terms of the partnerships and friendships we are invested in.
Here's why mutable signs Gemini, Sagittarius, Pisces and Virgo will be most impacted by the new moon.
Gemini
If you’ve been having some bad luck in the love department lately, the tides will turn. This planetary lineup is ideal for sparking conversations and forming new connections, so be sure to put yourself out there over the next several weeks.
While you will feel motivated to couple up or fix all relationship problems, don't put pressure on the matter now. Austere Saturn and tender Neptune have a square to love-oriented Venus, which can lead to heartache if you don’t brace yourself and take your emotions in stride.
Similarly, avoid the temptation to return to toxic situations, as the comfort you feel will be fleeting and can ultimately get in the way of your next great love.
Luckily, the new moon is putting your mind back in the game when it comes to romantic clarity.
Virgo
The new moon in Sagittarius gives you a sense of optimism and confidence that you are happy to bestow upon others. Even if you encounter a few holiday grinches, your shine and charisma are likely to be contagious. People will feel both comforted and at peace when they are around you.
Just make sure you’re not expending all of your energy on others, and plan a reprieve from socialization. If you’re hoping to connect with close friends and family, you may feel a gentle flow of energy that manifests from the lunation, which can help you cultivate a fun dinner party at home.
One thing: Try not to be overly expressive of your feelings, as it may lead to you putting your foot in your mouth.
Sagittarius
You’ve been under a lot of pressure, which is why the new moon in your sign offers you a moment of stillness and resolve.
Take some time out of your busy schedule to practice self-care, as the new moon prompts you to recommit to balance after the chaos that this time of year brings. Getting yourself back to a relaxed and grounded headspace can help prepare you for the romance to come.
Be cautious of tension with family and friends. These vibes are sure to shake things up within your personal, professional, and romantic life, bringing about a bout of intense energy with it. Avoid trying to force anything now, as it will likely backfire. So, save the hard and intense conversations for another day, when you can handle it. Instead, try to make the most of a quiet morning and a peaceful evening.
Pisces
You will focus more on asserting yourself during the new moon. Stand up for yourself. You might get the praise you want; you might not. But you will get a sense of self-respect.
This is especially urgent at work, where you may be experiencing tension (or jealousy) among colleagues. All will be smoothed over eventually. However, in the meantime, you will be able to discern who your trusted colleagues are and who are not.
