In 2025, Mars, the planet of action, energy and ambition, will have a major impact on the zodiac sign Gemini, the sign of communication and intelligence. From January 21 to April 2, 2025, Mars will transit through Gemini, meaning all zodiac signs should prepare to experience a flurry of action and excitement this time. In a contrasting scenario, however, the Moon sign of individuals would decide how Mars in Gemini would work for them. The Moon represents emotions, instincts, and inner self. The effects will be further understood using a person’s birth chart and how this particular transit impacts them.
