Firdaria Doctrine
Definition
Firdaria is presented here as a planetary period timeline, with different starting sequences for day and night births.
The public description names the currently reviewed lane without implying that all historical firdaria variants have been settled.
History and sources
The local notes connect the active lane to medieval Persian and Arabic transmission, while modern Hellenistic sources provide context for time-lord families more generally.
the overview avoids treating later reconstruction choices as source language.
How it is calculated
The active lane uses separate diurnal and nocturnal major-period sequences, a seventy-five-year cycle, and equal seventh-part subdivisions inside planetary periods.
The lunar nodes are treated as terminal periods in this lane and do not receive the same subperiod subdivision as the seven planets.
Variants
The cited materials preserve a larger firdaria family, including possible differences in node placement and subdivision policy.
this overview describes the reviewed equal-subperiod lane only.
What this doctrine covers
The cited material supports reference pages for the major and subperiod timeline, the day-night sequence distinction, and the seventy-five-year cycle.
It does not publish interpretive blending with transits, profections, or revolutions.
Scope and limitations
The current description should not be used as a universal claim about every firdaria tradition.
Interpretive outcome language remains outside this overview until separate facts or rules are reviewed.
Related practices
Firdaria belongs to the larger family of time-lord and period techniques, adjacent to profections, decennials, and revolution-year work.

When the active firdaria subperiod is ruled by the same lord as the major period, this indicates Abu Ma'shar's rule that the subdivision begins with the period lord itself.
2 locator entries
The active firdaria major lord can be read as the current Persian period lord descending from the sect-light sequence.
2 locator entries
When a nodal firdaria period is active, this indicates Abu Ma'shar's terminal Dragon's Head or Tail phase directly.
2 locator entries
The active firdaria sub-lord can be read as the equal seventh-part subdivision of the current Persian period.
