What your Part of Fortune is
The Part of Fortune (Pars Fortuna) is the best-known of the Arabic Parts — a point calculated from the relationship between your Ascendant, Sun, and Moon. It marks where the three most personal factors in your chart line up, and it is traditionally read as a place of ease, flow, and well-being. This calculator returns its exact sign and house from your birth chart.
Why day and night charts change the result
The Part of Fortune uses one formula for day (diurnal) charts and the reverse for night (nocturnal) charts — whether the Sun was above or below the horizon at your birth. Skipping that step is the most common way the point is miscalculated, and it can move the Part into a different sign and house entirely. This tool checks your chart's sect automatically and applies the correct formula.
How to read your Part of Fortune
Read the house of your Part of Fortune as the arena where things tend to come together with less force than you expect — where alignment, timing, and a sense of rightness show up. The sign describes the style that unlocks it. It is broader than money: think of it as where your chart is most naturally at home, and a good place to invest energy when you want momentum.
