The last full moon of 2025 in the sign of Gemini
Supermoon December 2025 – The St. Nicholas Full Moon on December 5th brings a chance to heal relationships
What the December Full Moon in Gemini Brings
This year, the December full moon falls on the night of December 4th to 5th, when the so-called "Cold Moon" peaks at exactly 00:14 CET. This is the last supermoon of 2025 and takes place in the air sign of Gemini. Gemini symbolizes not only communication, but also inner duality, thinking and relationships between people.
This full moon isn't just visually powerful—it's a time of closure, reflection, and true communication. And that's what makes it a pivotal moment for each of us who has carried unspoken, unheard, or repressed feelings throughout the year.
Main themes: communication, conviction, inner cleansing
Full Moon in Gemini It brings to light everything related to the mind, speech, information – and also to the stories we tell ourselves.
1. Communication as a tool and a trap
Relationships suffer when we stop talking – or when we only talk about practical things. This full moon invites us to say things we have been holding back for a long time. Openly, calmly, but truthfully. Where we fear a reaction. Where we have become accustomed to silence.
2. Beliefs that no longer work
Gemini rules thoughts – but also those that are outdated. You might be surprised at how strongly patterns from the past affect you. Opinions you've picked up from others. Fears that aren't yours. The full moon gives you a chance to recognize them and let them go.
3. Internal inventory of the year
The weekend around the full moon will be ideal for recapitulation.
What left this year? What came in? What didn't you tell yourself?
Take time for silence, journaling, or talking to someone you trust. More healing can happen in this time than you realize.
Introspective vibrations of the number 7
This full moon falls under the numerological vibration of the number 7 – which brings a deeper need for spiritual understanding. We may feel an inner calling to find true meaning in love. Not as a relationship equation, but as an energy that flows.
The number seven teaches us that healing does not come from the outside, but from within. And that in order to love truly, we must first stop deceiving ourselves.
What can you do during this full moon?
- Write down everything you didn't say during 2025 - to yourself and others. And write down what you don't want to carry anymore.i.e.
- Calm down your communication outwards and intensify your communication inwards. Silence is sometimes a greater answer than words.
- Do a symbolic ritual of closure – a letter, burning, meditation, or conversation.
- Accept that not everything has to be resolved – some things need to be let go.
This full moon is like an internal inventory
...kind, but clear. It shows where we cling to old roles, where we put on masks, and where we fear the truth. And at the same time it brings a chance to let it all go.
Action plan:
- Set aside 30 minutes just for yourself – preferably on December 4th or 5th.
- Write 3 sentences that you didn't say this year, but should have.
- Think of one thing you won't take with you until 2026.
