Decanate Cards: The Hidden Layer of Your Sun Sign
The Decans are 36 groups of stars (small constellations) which rise consecutively on the horizon throughout each earth rotation. Since a new decan appears every ten days, the ancient Greeks called them dekanoi (pl. of dekanos) or "tenths". In Vedic astrology, each sign of the zodiac (30 deg.) is divided by three decans, 10 degrees each. There is the trinal calculation which utilizes the elemental trines to each sign. Each decan has its planetary ruling planet or planets. To find Decanate cards, we use the same method as with the planetary ruling cards. All we need to know is planets that rule the Decan of our Sun placement (in the astrological birth chart). It can be one or two ruling planets, and therefore one or two decanate cards (see table below).
Please, note that dates below ruling planets of each decan are approximate. To be precise, you need to find the actual degree of your Sun placement in your astrological birth chart.
