The word Firdaria means
"Planetary Period". It is a certain kind of method giving its planet certain rulership through the course of life.
First I will give short introduction of the method, then I will give some quotes by the medieval astrologers of using the Firdaria.
Once again I need to stress how much important is having a good delineation of the natal chart before using any kind of Predictive Technique. I will stress out that the native chart is showing the promise of WHAT, and the predictive technique the time of it or WHEN.
The Firdaria rulership of the planets is showing the overall clime of certain period, it is a certain kind of overall biography of that period of your life, and when summing them all up, biography of the whole life.
For calculating the Firdaria you can visit the following site specified for it:

Do not forget to click on the day/night button in order to determine the application to count according to your geniture.
Or download the new version of the Morinus software which is specified for traditional astrology and you can find it free on web (just google it).
Lets start with the examination of the method.
This is a circle on which you can see the Chaldean order of the planets:
Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon.
But if you walk with the seven pointed star you can actually see the order of the planets according to their rulership with the days of the week:
Saturn - Saturday (Saturn-day)
Sun - Sunday (Suns-day)
Moon - Monday (Moons-day)
Mars - Tuesday
Mercury - Wednesday
Jupiter - Thursday
Venus - Friday
Each planet rules certain amount of years in the chart.
Sun rules 10 years.
Venus 8
Mercury 13
Moon 9
Saturn 11
Jupiter 12
Mars 7
North Node 3
South Node 2
If a person is born through the day (day chart) the sequence of the rulership begins with the Sun. Sun rules the first 10 years of the life of the person. Next 8 years are ruled by Venus, third by Mercury and so on according to the Chaldean order of the planets.
In a night chart the sequence begin with the Moon.
There are also sub-period rulers which goes the same.
Sun-Sun is the first sub-period.
Sun-Venus the 2nd.
Sun-Mercury the third and so on.
This is the method.
When you know that some period is ruled by certain planet you look at that planet in your chart; its position, zodiacal state, local determination (by house), its aspects and etc.
Then, for further details you look for the ruler of the Sub-Period.
So, the planet ruling the period is having 'the last word' but the ruler of the sub-period is also very important.
People often married (altough this is not the general rule) when the ruler of the 1st and the 7th are rulers of the Firdaria period.
I have often seen Sun ruling the sub-period in women's chart is indicating marriage in those years.
What I often do when some client ask me for times for marriage to look at the ruler of their 7th and the Sun (of they are female), to be Firdaria ruler or sub-ruler. It is often the case to be like this, but it is not of a 'must be' rule.
Here is why delineating the natal chart is of much importance.
What if Marriage is not promised in the natal figure? I know that this is often hard to tell, but there are occasions when the natal chart is showing difficult times or no hope for marriage, and it is very stupid to predict marriage of such a person, you only fire up the Hope and Eagerness in that person. I know that this sounds too deterministic, but traditional astrology in many ways is like that. I don't think that we do not have any amount of free will, but this will is limited, there are greater powers which are playing role here. Maybe God is having some other plan for that person, and Astrology for me is a tool for reading God's intentions (though not God's Mind) and interpret them.
Lets examine this geniture.
The chart is of a male person.
First we need to give natal delineation of the chart.
This should be much more profound analyze but for the sake of time and place I would give a brief one.
It is a day chart.
Lady of the Ascendant is in the 4th, exactly on the IC.
This shows that the native will be favored by his father.
This also shows that the native will have very emotional nature and struggle with the reason (conflict between reason and emotions) because of the square between Moon and Mercury.
This struggle would give a conflict on the professional career and social status (Moon opposition MC, Mercury Square MC).
Sun is the only planet in the upper hemisphere, trying as much as it can to stay visible. It is making very strong square to the out of sect Malefic - Mars in the 4th.
The Sun is representing the native's father and the authority figures.
We can assume that the native would have conflict with his father and authority figures through out the life. They will make opposition (Sun opposite AC).
Venus is weak, peregrine and cadent in 6th.
The native's health it should be good because Sagittarius (of which the ruler is the Greater Benefic) is on the cusp of 6th while Jupiter is in the 6th. This is often indicator for good health, or of very weak illnesses.
Though Mercury on the Facies in 6th is indicating problems with the eyes.
Mars in 4th is indicating a violent father or a turbulence (and violence) in the home.
Saturn in 5th (note that it is in 4 orb toward the cusp of 5th) is indicator of struggles in the creativity, romances and etc.
Ok, this is it.
Lets now use the Firdaria.
Because the chart is a day one, we start with the Sun. So the Sun is ruling the first 10 years of Life.
We look for the state of the Sun in the natal figure.
Sun is in the 7th in detriment in square to Mars in 4th and in wide Trine to the Moon in 4th.
It is ruling the 2nd and having honor in 10th.
This is it. This is all we got.
This indicates that the first 10 years of life will be of a very turbulent nature. Struggles with the father, having difficult relationship with the father. Having an opposition from the authority figures and etc.
We would say that the most difficult period would be the Sun/Mars period because of the square in the natal chart.
And indeed it was. The native was beaten by the father very violently in front of his friends, something which he remembers whole of his life.It was devastating for its self esteem.
Venus rules from 10th till 18th year of life.
This was very struggling period for the native too.
Note the lonely Venus Peregrine in 6th. It is in the so called Galactic Station. No stars around it, no tide aspects. We can say that she is applying to out of sign conjunction to Jupiter in 6th but Jupiter is not very happy either.
Venus rules 4th and 11th and is having honors in 9th.
This was a time when the native was having struggling in finding his place in the Life: friends, love, home support and etc.
But it was very hard indeed. He had many fallen friendships (bad friends), some fallen loves and etc.
But from the other side he begin with Music (music is promised in his chart by the applying sextile from the chart ruler and Almutem Figuris - Moon).
He begin to play guitar, to sing and formed a band.
But it was a very hard life all in all. He was kicked out from the school (Venus has dignity in 9th). He had domestic troubles, especially with his mom and etc. All that you would expect from unfortunate Venus (Peregrine, Cadent and no notable aspects).
The third period is ruled by Mercury.
Mercury is not very happy either. It is in the 6th, ruling 3rd and 12th.
In square to the MC, Moon and conjuncting Jupiter.
These were years where the native start to read a lot, enrolled musical school and finished it with great results.
But the struggles was in the career status. He was not happy in his overall life. He couldn't find his place into the world.
However, he learned a lot of skills, he got interested in Astrology as for his seek of Spirituality and Meaning in this world (conjunction with Jupiter ruler of 6th and 9th).
I think this is enough of this Firdaria delineation, just to give you some remarks and point marks of where we should go with the Firdaria analysis, and in which way to use it.
In the next comments I will give some quotes on using the Firdaira.
