Firdaria
Firdaria is a Persian time-lord system that divides a life into fixed planetary periods in a set order, each period subdivided into seven sub-periods ruled by the other planets in turn.
The order and the lengths depend on sect. A day chart begins with the Sun for ten years; a night chart begins with the Moon for nine. The full sequence runs seventy-five years before repeating, and the two nodes take a share in some traditions.
Like profection it is a filter rather than a prophecy: it says which planet is currently in charge, so its natal condition and the transits reaching it are the ones worth reading.
Frequently asked
Does firdaria depend on a day or night birth?
Yes, entirely. Sect decides both the starting planet and the order the periods follow, so a wrong birth time can invert the whole sequence.
How does it differ from profection?
Profection moves one sign a year on a twelve-year cycle; firdaria runs long unequal periods on a seventy-five-year one.
