Decano: Significato in Astrologia

A decan (or decanate) divides each 30° zodiac sign into three equal 10° sections. Each decan is sub-ruled by a different planet (traditional system) or by a different sign of the same element (modern system). Decans add a layer of nuance to any planet's sign placement — a planet at 5° Aries is in the first decan (ruled by Mars), while one at 25° Aries is in the third decan (ruled by Jupiter/Sagittarius).

First decan (0-9°59' Scorpio): Scorpio sub-tone, ruled by Mars/Pluto. Second decan (10-19°59' Scorpio): Pisces sub-tone, ruled by Neptune/Jupiter. Third decan (20-29°59' Scorpio): Cancer sub-tone, ruled by Moon. Each decan colors the Scorpio energy differently.

Your Sun's decan depends on its exact degree in your sign. If your Sun is at 0-9°59', you're in the first decan; 10-19°59' is the second decan; 20-29°59' is the third decan. Each decan of your Sun sign is further flavored by its sub-ruler.

Some horoscope content divides each sign into three groups and gives slightly different readings for each decan. This is more specific than Sun-sign horoscopes but less precise than a full natal chart reading.

Decans divide each sign into three 10° equal sections with a planetary sub-ruler. Terms (or bounds) divide each sign into five unequal sections, each with a different planetary ruler. Both are traditional subdivision techniques that add nuance beyond the basic sign placement.
