The details you enter are used only for the calculation and are not stored.

The idea behind it is simple: the distance between the Sun and the Moon is measured out from the Ascendant. This creates a «point of harmony» that joins conscious will (the Sun) with emotional needs (the Moon) and brings them down to the body and the world. Its sign describes how you find good fortune; its house shows the area of life where that fortune appears.

How is it calculated?

The calculation depends on whether you were born by day or by night. If the Sun was above the horizon (a day birth), the Part of Fortune = Ascendant + Moon − Sun; if the Sun was below the horizon (a night birth), the Part of Fortune = Ascendant + Sun − Moon. Some modern astrologers use the day formula in every case; this page follows the traditional method. Because the Ascendant changes within minutes, the Part of Fortune needs an accurate birth time.

How to read the Part of Fortune

When reading the Part of Fortune, look first at its house: this is the area of life where luck and ease show up most.

The ruler of the sign the Part of Fortune falls in also matters; the condition of that planet in the chart shows how easily you reach your fortune. Planets conjoining the Part of Fortune, and transits to it, highlight the themes of fortune at that time.
