Astrology: Firdaria?

[SeekerOfTruth666]

Does anyone know what firdaria really is and if it's a valid Astrological divination method? Recently i came across firdaria and couldn't find anything about it on our website or forum.
A quick google search came up with this:

Being a method of prediction of the Medieval Astrology, Firdaria draw an outline of a person's life. They associate different periods of life with different planets and thus define which theme will prevail during each of the periods.

The word Firdaria is plural for Firdar, and the latter, although comes to us from Persian Astrology, has the same Greek origin as the English word period. So basically, firdaria means periods of life.
