Firdaria
Firdaria is a time-lord technique used by medieval Persian and Arabic astrologers. Life is divided into periods ruled in turn by the seven traditional planets and the lunar nodes. In each period that planet takes the wheel; its themes and its condition in your birth chart set the tone of those years.
The lengths of the periods are fixed: the Sun 10 years, Venus 8, Mercury 13, the Moon 9, Saturn 11, Jupiter 12 and Mars 7, followed by the North Node with 3 years and the South Node with 2. Together they make 75 years, and then the cycle starts again. If you were born during the day the sequence starts with the Sun; if you were born at night it starts with the Moon.
Each planetary period is divided into seven equal sub-periods. The major period gives the broad theme of those years, while the sub-period colours shorter stretches of one to two years. Reading firdaria together with annual profections and transits lets you see the flow of time layer by layer.
How is it calculated?
First we work out whether the birth was by day or by night: if the Sun was above the horizon at the moment of birth (between the 7th and 12th houses of the chart) it is a day birth, and if it was below, a night birth. If you enter your birth time and place we calculate this for you; if you don't know your birth time you can choose day or night yourself.
For a day birth the order is the Sun, Venus, Mercury, the Moon, Saturn, Jupiter, Mars; for a night birth it is the Moon, Saturn, Jupiter, Mars, the Sun, Venus, Mercury. This is the Chaldean order of the planets. In both sequences the periods of the North and South Nodes come at the end. Some sources place the nodes straight after Mars for night births; we follow the more common order used by Abu Ma'shar.
Each sub-period lasts one seventh of its planetary period. The first sub-period is ruled by the period's own planet, and the rest follow in Chaldean order: in the Sun's period they run the Sun, Venus, Mercury, the Moon, Saturn, Jupiter, Mars. The node periods have no sub-periods. Years are counted in solar years from the moment of birth.
How to read firdaria
Start with the major period you are in: the themes of this planet are the big story of these years. Then look at the planet's condition in your birth chart. If it is in its own sign or its exaltation, the period tends to flow more easily and productively; if it is in a sign where it is weak, or under hard aspects, it asks for more effort. The house it occupies tells you in which area of your life the period will be felt.
Then turn to the sub-period. Its planet adds its own colour to the themes of the major period: the Venus sub-period of a Saturn period is a stretch where relationships and compromise come forward in the middle of serious structure-building. If the planets of the major and sub-period make harmonious aspects to each other in your chart, that stretch tends to go more smoothly.
Changes of period often coincide with the moments when life changes scene. The years in which one major period gives way to the next are often marked by big transitions such as finishing school, marriage, moving or a change of career. Comparing the period changes in your past with the events you remember is the best way to get to know the technique.
The planetary periods
- Sun period 10 years
- The Sun's period (10 years) is a time of identity, will and visibility. You clarify who you are, what you want and where you stand in life. Fathers, managers, authority figures and recognition come forward; stepping into view, taking responsibility and creative work are the themes of these years.
- Venus period 8 years
- The Venus period (8 years) is a time of love, relationships, beauty and pleasure. Romance, friendship and partnerships grow stronger, and you discover what you value and what is good for you. The search for harmony, art and taste, and your relationship with money and comfort become clearer in these years.
- Mercury period 13 years
- The Mercury period (13 years) is the longest of the firdaria: years of learning, thinking, communicating and gaining skills. School, writing, trade, short trips, siblings and your close circle come forward. Your mind is curious; you gather knowledge, learn a profession or a craft, and find ways to express yourself.
- Moon period 9 years
- The Moon's period (9 years) is a time of feelings, the body, home and family. Your need for security, your relationship with your mother and those close to you, making a home and giving or receiving care come forward. The rhythm of life may be more changeable; changes, moves and your bond with the wider public are among the themes of these years.
- Saturn period 11 years
- The Saturn period (11 years) is a time of responsibility, hard work and maturing. You deal with limits, delays and building lasting structures: career, authority, discipline and the test of time come forward. It can feel heavy, but whatever is built patiently in these years rests on solid foundations. Elders, tradition and coming to terms with the past are also themes of this period.
- Jupiter period 12 years
- The Jupiter period (12 years) is a time of growth, faith and expansion. Opportunities, teachers and mentors, higher education, long journeys and beliefs that give life meaning come forward. Generosity, optimism and a sense of abundance increase; these are often years in which you earn respect and share what you know.
- Mars period 7 years
- The Mars period (7 years) is a time of action, courage and competition. Your energy rises; you need to fight for things, defend your boundaries, take risks and clear your own path. Conflicts, sudden events and situations that call for care with your health may appear, while Mars energy aimed in the right direction brings determination and success.
- North Node period 3 years
- The North Node's period (3 years) is a time of increase and progress. In the tradition the North Node multiplies what it touches: new beginnings, gains and opportunities that move your life forward may arrive. This period has no sub-periods; the node rules alone for three years.
- South Node period 2 years
- The South Node's period (2 years) is a time of decrease, clearing and letting go. You leave behind habits, relationships or burdens that no longer serve you; what looks like a loss often makes room for a new cycle. This period has no sub-periods either; when it ends, the 75-year cycle starts again.
Frequently asked questions
What is firdaria?
Firdaria is a timing technique that divides life into periods ruled by the planets in turn. It comes from medieval Persian and Arabic astrology; in a 75-year cycle each planet gets a fixed length of time, and each period is coloured by that planet's themes.
Do I need my birth time for firdaria?
You don't need the exact time; what matters is whether you were born during the day or at night. If you know your time we calculate it from the chart; if not, choosing day or night is enough. For births close to sunrise or sunset an accurate time becomes important.
Why is the order different for day and night births?
In traditional astrology the Sun is the main light of a day chart and the Moon the main light of a night chart. That is why firdaria starts with the Sun for day births and with the Moon for night births, and the following periods are ordered from that starting point.
How is firdaria different from annual profections?
Profections give a ruler that changes every year, while firdaria gives major periods of seven to thirteen years and sub-periods of one to two years. Profections describe the detail of a year, firdaria the big chapters of life; read together they complement each other.
What happens after the age of 75?
The cycle starts again: day births return to the Sun's period and night births to the Moon's. Our calculator shows the periods up to the age of 90.
