Documented rules
4 documented rules
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.
The active firdaria major lord can be read as the current Persian period lord descending from the sect-light sequence.
When a nodal firdaria period is active, this indicates Abu Ma'shar's terminal Dragon's Head or Tail phase directly.
The active firdaria sub-lord can be read as the equal seventh-part subdivision of the current Persian period.
