What these decans are read as

The third decan of Capricorn is read as carrying a touch of Virgo and Mercury. It is the Capricorn who reads the small print. People here tend to plan in detail, to show love through remembering exactly what you said, and to be most at ease when the job is complicated and theirs alone.

The first decan of Aquarius is read as Aquarius twice over, Uranus and Saturn arguing it out. People here tend to hold firm opinions about how everything should work. In love they need a friend first, and at work they do best with a problem nobody has solved.

What the number 2 adds

Numerology reads a birthday that comes to 2 as the mark of a go-between. It tends to mean a gift for noticing what the other person needs, and a dislike of deciding alone when someone you trust is nearby.
