Your astrological birth chart is more than just planetary placements—and the Part of Fortune (or Pars Fortuna) represents a particularly favorable point. Essentially, your Part of Fortune sign placement reflects the areas of life where you find the most luck and success. Thus, it reveals a lot about how to overcome challenges and achieve your goals! Read on for a complete guide to Part of Fortune in astrology, including how to calculate it and what each sign placement means.
Things You Should Know
- Your Part of Fortune is the intersection between your Sun, Moon, and Rising signs on your birth chart. It represents areas where you find luck and success.
- Calculate your Part of Fortune with the formula Ascendant - Sun + Moon if you have a day chart (meaning your Sun sign is in houses 7 - 12)
- Use the formula Ascendant + Sun - Moon to calculate your Part of Fortune if you have a night chart (meaning your Sun sign is in houses 1 - 6).
Steps
How to Calculate Your Part of Fortune
-
Determine whether you have a day chart or a night chart. Depending on whether you have a “day chart” (meaning you were born during the day) or a “night chart” (meaning you were born at night), the formula to calculate your Part of Fortune differs. If your Sun sign falls in houses 7 through 12, you have a day chart. If it falls in 1 through 6, you have a night chart.
-
Find the degree of your Sun, Moon, and Ascendant signs. There are 30° of each sign (for a total of 360°). Birth charts typically display how many degrees into a sign each placement falls, so first, check yours for each value. For example, if you’re a Virgo Sun, your chart might say “Virgo: 19°,” meaning your Sun placement falls 19 degrees into Virgo. Then, since Virgo starts at 150° on a 360° birth chart, that means your Sun sign is located at 169° on the chart overall (since 150 + 19 = 169).Do this for your Moon and Ascendant signs, too! Using the 360° circle:
- Aries starts at 0°
- Taurus starts at 30°
- Gemini starts at 60°
- Cancer starts at 90°
- Leo starts at 120°
- Virgo starts at 150°
- Libra starts at 180°
- Scorpio starts at 210°
- Sagittarius starts at 240°
- Capricorn starts at 270°
- Aquarius starts at 300°
- Pisces starts at 330°
-
Follow the day chart formula Ascendant - Sun + Moon. Once you’ve figured out the exact degree of your Sun, Moon, and Ascendant, simply follow the formula to figure out where your Part of Fortune placement falls. If you have a day chart, subtract your Sun sign from your Ascendant and then add your Moon.[1] For example:
- Say your Sun sign in Virgo is 169°, your Moon sign in Taurus is 33° and your Ascendant in Libra is 200°.
- That means the formula for your Part of Fortune would be 200° - 169° + 33°.
- The result is 64°, which means your Part of Fortune placement would be in Gemini (since Gemini starts at 60° and ends at 90° on a 360° birth chart).
-
Use the night chart formula Ascendant + Sun - Moon, alternatively. If you have a night chart, use the same degree values for your Sun, Moon, and Ascendant in a slightly different order. Add your Sun and Ascendant, then subtract your Moon to find your Part of Fortune placement.[2] For example:
- Say your Sun sign is Aquarius at 323° (300 as the starting point for Aquarius + 23 degrees into Aquarius on your birth chart).
- Then, say your Moon sign is Leo at 146° and your Ascendant in Libra at 180°. That means your formula would be 180 + 323 - 146.
- The result is 357°, which means your Part of Fortune would fall in Pisces (since Pisces starts at 330° and ends at 360°).
