The December 4 Gemini full moon is the last full moon of 2025—and a powerful supermoon! Get curious and communicative and bring big ideas to life.

Gemini full moon (supermoon): December 4 (6:14PM; 13°04’)

Wordplay, wit and wisdom: let’s go! Everyone’s got a story to tell under the loquacious full supermoon in Gemini on Thursday, December 4. This is one of the best days in 2025 to articulate your dreams, desires and wishes aloud. (The universe IS listening!) Drop or debut or just get the buzz going.

Gemini rules peers and platonic partnerships, so why go it alone? Post plans to social media and see who wants to help you manifest your vision. Whatever you do, surround yourself with uplifting people today because vibes are contagious. A creative partnership could turn into an official dynamic duo within two weeks of December 4.

Silver-tongued Gemini energy can bring out some slickness. (Consider yourself warned.) Plus, with manipulative Pluto and seductive Venus influencing this supermoon, it’s almost too easy to get a “yes” out of people. But are you ready to deliver on your promises? Don’t get so caught up in this heady supermoon swirl that you lead people on—or worse, get tangled up in a situation that’s way above your pay grade.

And while 2025’s final Mercury retrograde is over, (thank goddess!) the “retroshade” shadow period continues through December 16. If an idea you’re pursuing could use some legal protection, don’t cut corners. Reach out to an attorney and protect your data with all the passwords and firewalls.

Don’t bury yourself in your phone while you’re out and about! The partnership-powered Gemini full moon has a special way of connecting kindred spirits—anywhere from the UPS Store to the gingerbread latte line. Stop scrolling and check out the humans in your IRL field of vision. If you sense a spark of potential (or soul recognition!), it never hurts to make eye contact and (gasp!) say hello.

Single? Ask questions, get curious. The best way to be interesting during a Gemini full moon is to be interested. Plus, you could find out some fascinating deets about people you THOUGHT you knew!

Coupled? Turn your S.O. into your adventure buddy. Hit the indoor pickleball court, go see a play or live music—with or without a crew of mutual friends.

How to make the most of the Gemini full moon

Partner up. Don’t go it alone under these dynamic-duo moonbeams. Someone in your circle (or a degree of separation away) could be sitting on resources that help you manifest your vision. Alliances that have been bubbling over the past six months (since the Gemini new moon, on May 26, also a supermoon) may formalize into a bona fide partnership.

Act locally. Don’t sleep on the locals as Gemini is the sign that rules our neighborhood vibes. Your perfect plus-one could be closer to home than you realize. Circulate!

Share your perspective. Post thoughtfully about your passions and share your original views. With the full moon in this communicative sign, you never know who might be moved by your message.

Update your transportation. Gemini rules all things with wheels, so if you’re searching for a new car or bike, let this full moon light the way to the perfect car or mobile accessory for commutes. Shop around with care since the Mercury retrograde shadow lingers until December 16.

What you don’t want to do. Avoid delivering any scathing critiques or play devil’s advocate because you’re bored.
