The Part of Fortune is the best known of the Arabic Lots, a point that blends your Sun, Moon and ascendant to show where ease, joy and good fortune flow most naturally. Enter your birth details and this calculator finds your Part of Fortune by sign and house, then describes the area of life where you find flow and a sense of being in the right place.
What the Part of Fortune Is
The Arabic Lots, or Parts, are calculated points drawn from the angles between planets, used since ancient and medieval astrology. The Part of Fortune is the most important of them. It combines the three pillars of the chart, the Sun for spirit, the Moon for body and the ascendant for the self, into a single point of natural wellbeing.
How It Is Calculated
By day the formula adds the ascendant and the Moon, then subtracts the Sun. By night the order of the Sun and Moon is reversed. The calculator applies the correct day or night version automatically, since using the wrong one places the point in the opposite part of the chart. The result is a sign and degree like any other point.
What Your Part of Fortune Shows
The sign of your Part of Fortune colours the style of your good fortune, while the house shows the area of life where it appears. A Part of Fortune in the tenth may bring satisfaction through career and reputation, in the fifth through creativity and joy, in the second through resources and self-worth. It often marks where things simply feel right.
How It Is Read
The Part of Fortune is read as a place of flow rather than guaranteed luck. Planets that sit near it or aspect it shape how easily its promise comes through. It is a gentle, supportive point, best used to notice where you thrive rather than to predict events.
How to Use the Result
Use the Part of Fortune to spot the area of life where ease and satisfaction come most naturally, and lean into it. Because the formula uses the ascendant and the day or night distinction, an accurate birth time is essential for the point to land correctly.
