Derived Houses in Astrology: How to Read the People in Your Life from Your Birth Chart
Derived Houses in Astrology: How to Read the People in Your Life from Your Birth Chart
Your birth chart is not only about you. It also holds symbolic information about your partner, your parents, your children, your friends and even your bosses. The key to reading it lies in a classic and remarkably powerful technique: derived houses, also known as turned houses or rotated houses. At Aspectados we explain how they work, with clear examples, so you can start applying them to your own chart today.
What Derived Houses Represent in Astrology
The basic idea is simple: any house can be treated as if it were a new 1st house, and from there you count all twelve houses again. Their symbolism includes:
- People around you: the 7th house is your partner, the 10th (or the 4th, depending on the tradition) one of your parents, the 5th your children, the 11th your friends.
- Those people's affairs: your partner's money, your children's health or your mother's career.
- Nuances of your own topics: for example, the "2nd from the 10th" describes the income your career generates.
- A finer-grained reading: it lets you answer specific questions without needing another person's chart.
- A traditional technique: used since Hellenistic and medieval astrology and still very common in horary astrology.
One important caveat: derived houses describe how you experience that person or matter, not an objective portrait of the other person.
How the Technique Works Step by Step
Step 1: Choose the starting house
Identify which house represents the person or topic. Your partner is the 7th house; your siblings, the 3rd house; your children, the 5th house; your friends, the 11th house.
Step 2: Count from it as if it were the 1st
That house becomes the "derived 1st house." The next house is its 2nd, the following one its 3rd, and so on. The starting house always counts as number one.
Step 3: Apply the usual meaning of the house
The derived 2nd still speaks of money, the derived 6th of health and routines, the derived 10th of career. The only thing that changes is whose life we are talking about.
Step 4: Interpret signs, rulers and planets
Look at the sign on the derived cusp, where its ruler is placed and which planets occupy that house. This adds texture and detail to the reading.
A handy formula: derived house = (starting house + house you want − 1), subtracting 12 if the result is greater than 12. For example, the 2nd from the 7th is 7 + 2 − 1 = 8th house.
Classic Examples of Derived Houses
Your partner's money: the 8th house
The 2nd from the 7th is your 8th house. That is why the 8th is traditionally linked to shared resources, inheritances and the spouse's money. If you have Jupiter there, astrologers read it as a partner who may bring resources or financial generosity into the relationship.
Your partner's career: the 4th house
The 10th from the 7th is your 4th house. Your partner's profession may therefore show up in your domestic life: perhaps they work from home, or their career shapes where you live together. It is a great example of how derived houses connect areas of life that seem unrelated.
Your partner's siblings: the 9th house
The 3rd from the 7th is your 9th house. That is why, in traditional astrology, the 9th also describes your in-laws, especially brothers- and sisters-in-law. Planets in the 9th can describe how you get along with your partner's family.
Mother and father: the 4th and 10th houses
Depending on the school, the 4th house represents one parent and the 10th the other. The 2nd from the 4th is your 5th house: that parent's resources. The 10th from the 4th is your 1st house, suggesting that a parent's "career" or public legacy is reflected in you.
Your children's health: the 10th house
The 6th from the 5th is your 10th house. It is one of those surprising connections: your professional life and your children's health share a derived house, something many parents recognize when they have to balance work and caregiving.
Friends of friends: the 9th house
The 11th from the 11th is your 9th house. Second-degree networks and friendships born during travel or study fit this symbolism nicely.
Your second marriage: the 9th house
Some traditions associate a second committed partnership with the 9th house, following the logic that the 3rd from the 7th represents "the next one" in the series. Other schools use the 11th for a third bond. It is a debated reading, but it shows how flexible the system is.
Income from your work: the 11th house
The 2nd from the 10th is your 11th house. It is no coincidence that tradition called the 11th "the house of good fortune" and linked it to the rewards of one's profession.
Practical Tips for Using Derived Houses
- Start with specific questions: "How do I experience my partner's money?" is far more useful than trying to read everything at once.
- They do not replace the other person's chart: if you have their birth data, their own chart will always be more precise. Derived houses show your experience of that person.
- Look for confirmation: if the derived house and the natural significator (for example, Venus for a partner) say the same thing, the reading gains strength.
- Be consistent with your house system: derived houses work with whole sign, Placidus or any other system, but do not mix systems within the same reading.
- Combine them with transits: a transit through your 8th house may coincide with changes in your partner's finances. This is an excellent way to deepen your transit analysis.
- Avoid determinism: a challenging derived house does not doom anyone. It describes tendencies and dynamics, not fixed destinies.
Conclusion
Derived houses turn your birth chart into a map of relationships: every house contains another twelve, and with a little practice you will be able to see the important people in your life, and the matters you share with them, within your own chart. It is a technique that rewards patience and curiosity.
