A ten-degree subdivision of a thirty-degree zodiac sign.
Why it matters
Dividing each 30° sign into three 10° decans gives astrologers a finer way to describe positions within a sign. Decan rulership systems vary by tradition.
Example
A planet at 7° Leo is in the first decan of Leo; a planet at 17° Leo is in the second decan.
Common confusion
Decans do not create extra zodiac signs. They are subdivisions within the twelve signs.
