October 2025 could present some difficulties for Aries, according to the monthly horoscope for that sign. Sometimes the results are unsatisfactory and mixed. The transit of the Sun will be covered first. You will enjoy a fortunate transit of the Sun till October 17th. After October 17th, though, the Sun's weak position in the seventh house can make it less effective in bringing you good fortune. Until October 27th, Mars will be in your seventh house, which is typically seen as an unlucky transit. When October 27th rolls around, Mars will enter your eighth house. Mars is in its own sign, which could lead to fortunate outcomes in certain situations, but generally speaking, it's not a good omen.
