What these decans are read as

The first decan of Libra is read as Libra twice over, Venus weighing both sides. People here tend to hear the other person out before they have decided what they think. In love they want a real partner, and at work they are the one who stops two colleagues falling out.

The third decan of Virgo is read as carrying a touch of Taurus and Venus. It is the Virgo who enjoys the result as well as the method. People here tend to like good materials and quiet comfort, to love in practical, physical ways, and to do their best work at their own steady pace.

What the number 5 adds

Numerology reads a birthday that comes to 5 as the mark of a free mover. It tends to mean a low tolerance for routine, a taste for change and travel, and a need for a partner who doesn't keep score of where you were.
