By paying attention to the favorable and unfavorable days of the month, we can organize our lives more consciously: plan important meetings, avoid unnecessary stress, and postpone risky actions. The lunar calendar for September 2025 on Joy-pup is a practical tool for those who want to be in harmony with the rhythms of the Universe.
Astrological and Energetic Background of September 2025

September 2025 is not just another autumn month. It is a time when the energy of nature gradually changes, preparing us for a new cycle. During such transitional periods, it is especially important to consider the influence of astrological factors. Lunar phases, planetary positions, and retrograde motions all affect our activity, emotions, and even the effectiveness of our actions.
The main astronomical events of the month will be the New Moon on September 21 in Virgo and the Full Moon on September 7 in Pisces. The New Moon will provide a powerful impulse for starting new endeavors, especially those requiring a clear plan. The Full Moon in September, on the other hand, will be emotional, raising intuitive and spiritual themes. Pluto remains retrograde, encouraging a reassessment of long-term commitments and life structures.
From an energetic point of view, September 2025 is filled with a transitional vibration—from the brightness of summer to the reflections of autumn. It is a time of gradual slowing down but with high mental activity.
Favorable Days in September 2025

September will have several truly powerful days when energies favor productivity, constructive communication, and positive beginnings.
On September 2, the Moon is waxing and in Capricorn, making it ideal for organizing, starting projects, cleansing rituals, and medical check-ups.
On September 6, harmonious aspects form between Mercury and Jupiter—an excellent day for negotiations, learning, and starting collaborations.
Although the Full Moon on September 7 brings emotional intensity, it is perfect for completing tasks, reflecting on progress, and spiritual practices.
On September 10, the Moon moves into Taurus, and Venus forms positive aspects, creating an atmosphere of romance, creativity, and diplomacy.
On September 24, when the Moon is in Sagittarius and the Sun interacts with Jupiter, trips, legal initiatives, and broadening horizons will be especially successful.
The month concludes on September 28, a day filled with inspiring energy: the waxing Moon and a trine between Venus and Uranus create an atmosphere of unexpected happiness, fresh ideas, and creative breakthroughs.
All these dates can be used for active undertakings, launching projects, investments, romantic meetings, and travels.
Unfavorable Days in September 2025

Despite the generally favorable flow of the month, there are dates when extra caution is advised.
The most tense period is September 4. This time is prone to misunderstandings, calculation errors, and delays. It is especially important not to sign important documents impulsively and to double-check everything.
September 13 may bring emotional disruptions and disagreements, as the Moon forms tense aspects with Mars. It is not the best time for frank conversations or settling disputes—conflicts and hurt feelings are possible.
On September 20, avoid financial decisions and major purchases. The planetary configurations on this day increase impulsiveness and may lead to unnecessary expenses or dubious deals.
Be careful on September 25. Old misunderstandings or technical glitches may resurface. It is better to focus on inner work rather than external achievements.
How to Use This Knowledge in Daily Life

To make September as harmonious and productive as possible, it is worth planning important matters in advance according to the astrological calendar. Schedule key actions on days with favorable energy: negotiations, visits, and new beginnings during the first and fourth weeks of the month. Avoid overloads and hasty decisions near the 7th and 20th.
Unfavorable days can be used for routine work, inner analysis, and rest. If important events must take place during these periods, practice maximum mindfulness, double-check everything in advance, and do not give in to emotions. Proper planning will help you avoid troubles and unlock the full potential of this month.
