How to Identify Your Decan

This decan covers 20° up to but not including 30° of Gemini.

Use your Sun's tropical sign and degree to identify its decan. Calendar dates are approximate; your birthday alone may not settle a boundary placement. If your birth time is unknown, a representative position near a boundary may leave your decan uncertain.

This collection uses modern triplicity: sub-rulers follow the signs of the same element. Other systems, including Chaldean decans, assign different rulers. The descriptions below are interpretive traditions, not measured personality traits. Compare the decan methods at Astrodienst.
