Determine your Pars Fortunae to discover areas of natural success and prosperity in your natal chart.

What is Calculate Part of Fortune?

To calculate Part of Fortune is to find one of the most significant "Arabic Parts" in a natal astrology chart. Also known as Pars Fortunae, this mathematical point represents a unique synthesis of the three most important pillars of a birth chart: the Sun, the Moon, and the Ascendant. When you calculate Part of Fortune, you are identifying a specific degree in the zodiac where your physical body (Ascendant), your conscious spirit (Sun), and your emotional soul (Moon) harmonize to create a point of natural well-being and prosperity.

Who should use this tool? Anyone interested in Hellenistic or modern astrology who wants to understand their innate talents and where they might find "good luck" or worldly success. A common misconception is that the Part of Fortune acts like a winning lottery ticket; in reality, it indicates where your efforts will feel most supported by the universe and where you find the most joy.

Calculate Part of Fortune Formula and Mathematical Explanation

The math behind the calculate Part of Fortune process depends entirely on whether you were born during the day or at night. This is known as "Sect."

• Day Birth Formula: Ascendant + Moon – Sun
• Night Birth Formula: Ascendant + Sun – Moon

To perform this calculation manually, you must first convert the zodiac positions into "absolute degrees" (0° to 360°). For example, 10° Taurus is 40° in absolute terms (30° for Aries + 10°).

Variable	Meaning	Unit	Typical Range
Ascendant (Asc)	The Rising Sign degree	Degrees (°)	0° – 359.9°
Sun	Position of the Sun	Degrees (°)	0° – 359.9°
Moon	Position of the Moon	Degrees (°)	0° – 359.9°
Sect	Day or Night birth	Binary	Day / Night

Practical Examples (Real-World Use Cases)

Example 1: Day Birth

Suppose an individual has an Ascendant at 15° Leo (135°), Sun at 10° Aries (10°), and Moon at 5° Gemini (65°). Since the Sun is in Aries (a spring sign) and assuming it's above the horizon:

Calculation: 135° (Asc) + 65° (Moon) – 10° (Sun) = 190°.
190° corresponds to 10° Libra. Their Part of Fortune is in Libra.

Example 2: Night Birth

If the same person was born at night, we use the night formula:

Calculation: 135° (Asc) + 10° (Sun) – 65° (Moon) = 80°.
80° corresponds to 20° Gemini. Their Part of Fortune is in Gemini.

Key Factors That Affect Calculate Part of Fortune Results

• Birth Time Accuracy: The Ascendant moves approximately one degree every four minutes. An incorrect birth time will significantly shift the Part of Fortune.
• Sect (Day vs. Night): Using the wrong formula is the most common error when people calculate Part of Fortune.
• Zodiac System: Most use Tropical astrology, but Sidereal calculations will yield different results.
• House System: While the degree remains the same, the house placement of the Part of Fortune changes based on the house system (Placidus, Whole Sign, etc.).
• Planetary Aspects: Any planet conjunct your Part of Fortune will greatly influence how that "fortune" manifests.
• Lunar Phase: Since the formula uses the distance between the Sun and Moon, the Part of Fortune is essentially the Moon's position relative to the Ascendant.
