The new moon in Sagittarius reaches its peak at 3:43 am on 20 December 2025 (South Africa Standard Time).
This lunation takes place in Sagittarius, a mutable fire sign associated with spontaneity, curiosity and a willingness to embrace adventure. Mutable signs mark transitions between seasons, and this brings a sense of flexibility, movement and openness to change. Sagittarius is ruled by Jupiter, the planet of growth, exploration and knowledge. Its influence encourages us to pursue new horizons, trust in what lies ahead and direct our attention towards the future rather than staying anchored in present limitations. The tone of this new moon is therefore optimistic, expansive and forward-looking.
The moon sits at 28 degrees, which falls in the third decan of Sagittarius. This decan is linked to the Ten of Wands in the tarot, often referred to as the Lord of Oppression. Co-ruled by Saturn, it highlights themes of pressure, responsibility and the final push required to complete a cycle. This energy can feel polarising. Situations may reach a point where you are either breaking through or recognising that something has come to its natural end. There is a sense of culmination that asks for perseverance and honesty.
The moon forms a conjunction with Venus and Mercury, both also in Sagittarius, which supports warm, charismatic and easy-flowing communication. However, Neptune at 29 degrees of Sagittarius introduces an element of uncertainty. This influence can bring a risk of idealising a situation or placing hope in something that may not be realistic. For some, it may feel like a subtle sense of confusion or even a limitation on self-expression, creating moments of hesitation or doubt.
Mars, meanwhile, is exalted in Capricorn. This placement strengthens discipline, strategy and the ability to take practical action. It is an excellent moment to establish a grounded plan and commit to steady progress. While the Sagittarian energy encourages vision and possibility, Mars in Capricorn offers the structure needed to turn inspiration into tangible results.
