Frequently Asked Questions
What is an Arabic part (lot)? ›
A mathematical point usually derived as "Ascendant + planet A − planet B". It is not a physical body; it is read as the focal point of a specific life theme in the chart.
How is the Part of Fortune calculated? ›
By day: Ascendant + Moon − Sun; by night the formula reverses to Ascendant + Sun − Moon. Day or night is decided by whether the Sun is above or below the horizon.
Why does the day/night rule matter? ›
Classical sources reverse many lot formulas for night births. Skipping the rule moves the lot by twice the distance between the two factors, up to the opposite side of the chart (180°). Maxis applies each lot’s reversal rule per the classical sources.
Which lots are calculated? ›
Twenty-five classical lots, led by the Parts of Fortune and Spirit, covering themes such as marriage, children, career and illness — each listed with its formula and exact degree.
