Frequently asked questions

What is a decan?

Each sign (30°) is divided into three decans of 10°: first (0–10°), second (10–20°) and third (20–30°). Each decan is colored by a secondary planet, which nuances the sign: a 1st-decan Aries is not a 3rd-decan Aries.

How do I calculate my decan?

It depends on the exact degree of your Sun, hence on your date of birth (and, at the boundaries, on the time). Enter your date above: the calculation uses the real position of the Sun, not an approximate table.

Are decan dates fixed?

Approximately: they shift by a day depending on the year (leap years, exact time of the equinox). Hence the value of a real calculation rather than date ranges.
