Free Firdaria Calculator
Firdaria is a Persian-derived time-lord technique that assigns nine planetary rulers — the seven classical planets plus the lunar Nodes — to fixed-length major periods across your life, in an order set by whether you were born during the day or at night. This calculator finds your birth chart's day/night sect, lays out your full firdaria sequence, and shows which lord governs right now, down to the sub-period.How it works ↓

Firdaria is a Persian-derived time-lord technique: nine planetary rulers, the seven classical planets plus the lunar Nodes, each govern a fixed-length major period across your life, in an order that depends on whether you were born during the day or at night. Each major period further divides into nine shorter sub-periods ruled by the same nine lords, giving a two-layer timeline of planetary "chapters" and "sub-chapters."
Your day/night sect decides the entire lord sequence
Firdaria has two possible orderings of its nine lords, and which one applies to you comes down to a single fact: whether the Sun was above or below the horizon when you were born. The page states this outright as a day chart or night chart badge, so you don't have to work it out from your Sun's house position — it's shown directly, and it's the reason your sequence differs from someone else's even with the same birth date.
Nine lords divide the life into major periods of fixed length
Each of the seven classical planets plus the two lunar Nodes governs one major period, with each planet's period length fixed by tradition rather than tied to its own "mean years" the way decennials assigns them. The order runs Sun through Saturn (or the night-chart equivalent) followed by the Nodes, then repeats if you live long enough to complete the full cycle.
Each major period splits into nine sub-periods
Within every major period, the same nine lords take turns again as shorter L2 sub-periods, always beginning with the major lord itself before cycling through the rest in the same sect-based order. This gives firdaria a finer grain than profections' single yearly lord — you get a major theme and a shorter-range one nested inside it.
Your natal Ascendant sign sits alongside the sect badge
The page also shows your natal Ascendant sign for reference, since it's the anchor point the rest of your chart — and the other time-lord techniques on this site — are built from, even though firdaria's own sequence is keyed to sect rather than to the Ascendant directly.
Firdaria is the only sect-dependent technique in this set
Profections count forward from your Ascendant on a flat twelve-year cycle, decennials hand off rulership by fixed mean-years allotments starting from your Ascendant's ruler, and bounds convert degree widths into years — none of them change with sect. Firdaria is the odd one out: the same birth date at a different time of day produces a genuinely different lord sequence, which is why the day/night badge is the first thing to check.
Frequently Asked Questions
How do I know if I have a day chart or a night chart?
It depends on whether the Sun was above or below your horizon at birth. The page states this directly as a day chart or night chart badge — you don't need to work it out yourself.
Does firdaria use the same lords as decennials or profections?
It draws from the same set of classical planets plus the lunar Nodes, but the sequence and period lengths are fixed by sect rather than by Ascendant position or mean-years allotments, so the order and timing differ from both.
What are firdaria sub-periods?
Each major planetary period splits into nine shorter sub-periods ruled by the same nine lords, starting with the major lord itself before cycling through the rest in sect order.
