Your zodiac sign only tells part of the story when it comes to your personality and life path. Astrological decans reveal deeper insights into your character and destiny based on the exact date and time you were born. Read on to learn all about decans—and unlock the secrets encoded in the stars within your birth chart.

What Are Astrological Decans?

Decans are divisions of the zodiac signs into thirds of 10-degree segments. This dates back to ancient Egyptian astrology, when 36 decans aligned with significant stars rising just ahead of the Sun each day. Later, the Hellenistic astrologers connected the decans with planets as sub-rulers.

Each zodiac sign spans 30 degrees around the wheel. This means that there are three decans per sign, each approximately 10 degrees long. Your decan reveals your ruling sub-planet and element—adding nuance beyond your major zodiac energy.

How Are Decans Calculated?

Your decan is based on your exact birth date and time. To determine your decan:

  1. Identify your Sun sign based on date of birth.
  2. Note the exact degree of your Sun. You can retrieve this from your birth chart.
  3. The first 10 degrees of your sign will be Decan 1. The second set of 10 degrees is Decan 2, and the last 10 degrees will be Decan 3.
  4. Check which decan contains your Sun’s exact degree to find your correct decan ruler and traits.

Understanding your decan adds an extra dimension to your personality profile and life purpose interpretation. Read on to learn about the distinct flavor of each decan within the 12 zodiac signs.
