Zodiac compatibility: how is it judged?

Each person's sign

Each person's sun sign comes from their birth date; a Persian date is converted to Gregorian automatically, since the signs change in the middle of a Gregorian month.

How two signs stand

The distance between two signs on the circle of twelve says how they stand: the same sign, neighbours, friends, a square, a trine, a quincunx or opposites. The most harmonious are signs four apart, which share an element.

The elements

Fire, earth, air and water each have a manner. Air and fire wake each other, water and earth help each other grow, and fire with water or air with earth need more patience. The score comes from the aspect and the elements together; add the names and the partnership reading by abjad comes with it.
