Exact birth time required. Day/night sect and the Ascendant are part of every formula.
What an Arabic Lots calculator should show
A useful result should disclose whether the chart is diurnal or nocturnal, which formula tradition is used, the exact degree of every lot, and the ruler of the resulting sign. Without those details, two calculators can disagree without explaining why.
Why Fortune and Spirit come first
Fortune and Spirit form the foundation of the Hermetic set. Fortune describes embodied circumstance and what is received; Spirit describes intention and deliberate action. Eros, Necessity, Courage, Victory, and Nemesis extend that axis through the five visible planets.
Common questions
What is the Part of Fortune?
The Part or Lot of Fortune is a calculated point derived from the Ascendant, Sun, and Moon. Its formula reverses for night charts in the sect-aware Hellenistic method.
Why is exact birth time required?
Every lot starts from the Ascendant, which moves quickly. Birth time also determines whether the Sun is above or below the horizon and therefore which formula direction is used.
Which Arabic Lots does Regu calculate?
Regu calculates the seven Hermetic Lots: Fortune, Spirit, Eros, Necessity, Courage, Victory, and Nemesis.
