In Defense of Astrology - So called Shift of Signs - No Such Thing as "New Astrology"

Astrology is based on the seasons and the relationships between the planets (called aspects) and NOT what constellation is located behind the Sun when you were born.
The signs of the Zodiac are merely symbols and metaphors that divide the year into 12 different and equal "seasons". This partition is based on the proportions of day and night or light and darkness experienced throughout the year. Aries always begins on the first day of spring (aka the Spring Equinox), when the day and night are equal and the amount of light is growing. Libra, on the other hand, always begins on the Fall Equinox, when the day and night are also equal, but the amount of light is receding.
Astrology postulates, regardless of what constellation occupies the Equinox, that people born in the spring will exhibit characteristics such as high energy and optimism. They will be the kind of people who spring into action, the same way that nature buds into life after its long winter slumber.
A new study, published by the Nature Neuroscience Journal, found links between the season of birth and personality. It is proven that people born in the winter, i.e. Capricorns, are more at risk to suffer from SAD (Seasonal Affective Disorder), schizophrenia and depression. In Astrology, Capricorn, beginning on the longest night of the year, is associated with suffering, difficulties and pessimism. To quote the author of the paper, Professor Douglas McMahon, "Our biological clocks measure the day's length and change our behavior according to the seasons."
