Firdaria — Persian time-lords
Hellenistic · Year
Firdaria is a Persian time-lord system of medieval astrology: life unfolds as a fixed 75-year cycle of planetary periods, each ruled by one of the seven traditional planets plus the lunar nodes. Day births begin the wheel with the Sun, night births with the Moon, and each major period is subdivided among all seven planets in turn.
What it is
Firdaria (from Persian 'firdar', likely echoing the Greek 'periodos') is a planetary period system transmitted through Perso-Arabic astrology — Abu Ma'shar and al-Biruni describe it — and revived in the modern traditional-astrology renaissance. Unlike transits or progressions, it requires no ongoing sky: the entire schedule is fixed at birth, unfolding as a 75-year wheel of time-lords.
The system is sect-based. For a day birth (Sun above the horizon) the sequence runs: Sun 10 years, Venus 8, Mercury 13, Moon 9, Saturn 11, Jupiter 12, Mars 7 — seventy years through the seven planets in descending Chaldean order from the Sun — followed by the North Node for 3 years and the South Node for 2, completing 75. For a night birth the wheel starts instead from the Moon: Moon 9, Saturn 11, Jupiter 12, Mars 7, then Sun 10, Venus 8, Mercury 13, with the nodes' 5 years attached. After 75 years the cycle simply begins again.
Each planetary period colours its years with the nature and, crucially, the natal condition of its lord: a strong, well-placed Venus makes the Venus firdar a flourishing chapter; an afflicted Saturn makes the Saturn firdar a time of testing. The node periods are read through the nodes' natal sign, house and rulers.
How it is calculated
Step one is sect: determine whether the Sun was above the horizon (day birth) or below it (night birth). Day charts start the sequence with the Sun, night charts with the Moon, and the periods then follow in the fixed order with their fixed lengths — Sun 10, Venus 8, Mercury 13, Moon 9, Saturn 11, Jupiter 12, Mars 7, North Node 3, South Node 2 — laid out from the birth date.
Each planetary major period is divided into seven equal sub-periods. The first sub-period belongs to the major lord itself, and the remaining six follow in the same descending order around the wheel; the sub-period length is simply the major period divided by seven (e.g. the 13-year Mercury firdar yields sub-periods of 1 year 10.3 months). The node periods traditionally receive no subdivisions. One genuine controversy exists: for night births some medieval sources insert the nodes after Mars, mid-sequence, while others always append them at the end — modern software offers both conventions.
What it reveals
Firdaria reveals the chaptering of a life: which planetary agenda holds the pen in each stretch of years. The Sun firdar foregrounds identity, honours and the father; Venus — love, pleasure and alliances; Mercury — study, trade and writing; the Moon — home, body and the public; Saturn — labour, structure and endurance; Jupiter — growth, counsel and fortune; Mars — competition, risk and decisive action. The sub-periods refine this into roughly one-to-two-year episodes where two planetary voices combine.
The quality of each chapter is read from the natal chart, not from the symbolism alone: the period lord's sign dignity, house, sect status and aspects determine whether its years help or test the native. In modern traditional practice Firdaria is rarely used alone — it is layered with annual profections and solar returns, so that a theme flagged by the firdar lord can be confirmed and timed to a specific year.
Frequently asked questions
Where do the lunar nodes go in a night chart?
This is the famous Firdaria dispute. One convention keeps the nodes at the end of the wheel for both sects — North Node 3 years and South Node 2 years after the seven planets. Another, defended from readings of the medieval sources, inserts the nodes after Mars in night charts, i.e. in the middle of the sequence. Both are historically arguable; the practical advice is to test both against known biography and state which convention a given report uses.
How is Firdaria different from the Vedic Vimshottari dasha?
They are parallel inventions from different traditions and must not be mixed. Vimshottari is a sidereal, nakshatra-based 120-year cycle whose starting point depends on the Moon's natal lunar mansion. Firdaria is a Western-tradition system on the tropical zodiac: a fixed 75-year wheel whose entry point depends only on sect — day or night birth. Each is read within its own zodiac and its own interpretive framework.
What makes a Firdaria period fortunate or difficult?
The natal condition of the period lord. A lord in its own sign or exaltation, well placed by house, of the favoured sect and aspected by benefics tends to deliver its years generously. A lord debilitated, combust, retrograde in a difficult house, or afflicted by malefics marks a chapter of friction in its topics. The sub-period lord then modulates each slice — a hard major period can still contain supported sub-periods, and vice versa.
What happens after age 75?
The wheel simply turns again: at 75 the cycle restarts from the same first lord — the Sun for a day birth, the Moon for a night birth — and runs through the identical sequence. Medieval authors wrote little about the second cycle, since it exceeded typical lifespans; modern practitioners read it exactly like the first, often noting that the returning periods echo the themes their lords delivered seven and a half decades earlier.
