What are decans in Tarot and astrology? Decans in Tarot are astrological subdivisions that connect Minor Arcana cards to specific zodiac degrees and planetary energies. They’re used to deepen card interpretations, add timing elements, and enhance the richness of Tarot readings with astrological insight.

We start the 10 of Pentacles decan today; it’s September 12th- September 21st. In astrology, it is associated with Mercury or Virgo III, and Mercury is in Libra until October 1st. It begins the retrograde period in Scorpio on October 8th.

Venus rules Libra, and Venus is in Scorpio; the two are not talking to each other.

Mercury in Virgo was cleaning up and organizing communications. The goal with Mercury in Libra is to open lines of communication that are balanced and create fruitful exchange. But with Venus in Scorpio, Mercury doesn’t have its helper, and communication and commerce get weighed down in the trenches.
