Decans (Zodiac Sub-Traits)

See finer innate traits from your decan (10°), each sign split into three.

A decan is a 10° subdivision of each zodiac sign (30°) in Western astrology, dividing every sign into three. Even within the same sign, your decan carries a different sub-ruler (traditional triplicity), giving subtly different traits. Find your decan and its sub-ruler by your birth date and explore your personality, love, and work tendencies in finer detail.

How it works

Enter your birth date and we find your sun sign, then which of its three decans you fall in — the thirty degrees of a sign split into ten-degree thirds. Even within one sign, the beginning, middle, and end read differently.

What you'll get

You see the character of your decan and the sub-ruler that governs it alongside your sign, the texture of love and work, and this year's flow as the sub-ruler shapes it.

Frequently Asked Questions

How is a decan different from a sign?

It is a subdivision: the thirty degrees a sign covers, split into three ten-degree parts. Even within one sign, the beginning, middle, and end read differently.

How is my decan decided?

It follows from which ten-day stretch of the sign your birthday falls in. There is nothing to choose by hand.
