Winter promises to be rich in astrological events, and one of the brightest will be the Full Moon in December 2025. This is not just a bright light in the winter night sky but also an effective spiritual and symbolic marker: a moment of culmination, transformation, and illumination, when emotions reach their peak and hidden truths come to light. At Joy-pup, we will explore the December Full Moon, when it will occur, and its influence.
When the December Full Moon Will Occur – Exact Date and Time

In December 2025, the Full Moon will illuminate the night sky on December 5 at 01:14, on the 15th lunar day of the lunar calendar. This will be a Supermoon – the Moon will be at its closest distance to the Earth, making it appear brighter and amplifying its effects on tides, emotions, and the subconscious.
During this period, the celestial body will be in the constellation of Gemini, activating the axis of the mind: Gemini (an air sign ruled by Mercury) emphasizes logic, communication, and multitasking. From an astrological perspective, the Full Moon always symbolizes culmination, the completion of a cycle, and the revelation of what was hidden or started during the New Moon. It is a time of maximum energy, when emotions reach their peak and many subconscious processes rise to the surface, demanding awareness and resolution.
The December Full Moon is traditionally called the “Cold Moon.” This name, given by Native American tribes, perfectly reflects the harsh beauty and frosty atmosphere of late autumn and early winter, when nights become long and dark, and the temperature drops relentlessly. Other names – “Long Night Moon” or “Frost Moon” – emphasize the connection to the darkest time of the year, leading up to the winter solstice.
Full Moon in Gemini – Influence on Life

The December 2025 Full Moon will occur in the sign of Gemini. Gemini is an air sign ruled by Mercury, the planet of communication, intellect, and movement. What themes will the December Full Moon highlight?
- Communication and information: Important conversations, the revelation of truths, receiving key information, or the completion of projects related to writing, learning, or media may occur.
- Duality and choice: Gemini energy is often associated with duality. During this period, the need to make decisions, resolve internal conflicts, or find balance between two opposing viewpoints may become more pronounced.
- Mind versus emotions: The Full Moon in Gemini can trigger conflicts between rational thinking and deep emotional needs. It is important to find a way to harmonize these aspects.
- Travel and short trips: Issues related to logistics, local travel, or interactions with your immediate environment may come to a conclusion or require your attention.
Influence on various areas of life:
- Emotions and subconscious: Emotional sensitivity may increase. This is a good time for self-reflection and recognizing your true feelings regarding communication and relationships.
- Relationships: Misunderstandings may arise, or, conversely, important clarifications may occur in relationships with siblings, friends, or colleagues. Open and honest communication will be key.
- Career and finances: Projects related to ideas, marketing, or connections may reach their climax. New information influencing financial decisions may also emerge.
- Health and well-being: Nervousness or anxiety may increase, especially if there are unresolved issues. It is important to pay attention to breathing exercises and calming practices.
During the Full Moon in Gemini, it is recommended to focus on completing intellectual tasks, clarifying misunderstandings, and letting go of outdated ideas or communication patterns. This is not the best time to start something completely new but is ideal for analysis and preparation for future endeavors.
