Why this calculator is different
Arabic Lots are often presented as a long table with no indication of which day or night formula was used. Regu surfaces the chart sect, exact calculation, house, ruler, and closest contacts in one focused result.

Common questions
What is the Part of Fortune formula?
For a day chart, the traditional formula is Ascendant plus Moon minus Sun. For a night chart, Sun and Moon are reversed. The result is normalized to the 360-degree zodiac.
Do I need an exact birth time?
Yes. The calculation uses the Ascendant and chart sect, both of which depend on birth time and place. A small time difference can change the exact degree and sometimes the sign or house.
Which Arabic Lots does Regu calculate?
Regu calculates the seven Hermetic Lots: Fortune, Spirit, Eros, Necessity, Courage, Victory, and Nemesis.
