What the 7th house is responsible for
The classical astrologers gave the seventh house marriage, alliances, agreements and lawsuits — and, as is often forgotten, open enemies: the one who stands opposite you without hiding. It is the angle of sunset, and everything that comes to a person from outside, through another, was read from here.
Modern astrology reads the seventh house as a mirror: in a partner a person looks for and meets the qualities they see poorly in themselves. Hence the observation that people with a cautious Ascendant often choose pushy partners, and vice versa. Also here — any one-on-one relationship: a business partnership, co-authorship, a regular client, the lawyer on your case.
Where traditions differ. First — love: romance and falling in love belong to the fifth house, marriage and a long union to the seventh, and popular texts often mix them. Second — the house system: in Placidus the seventh house begins at the Descendant, while in whole signs it begins at the start of the sign opposite the Ascendant, and a planet near the Descendant may land in the neighboring house.
Analogy: Libra and Venus
The seventh house is compared to Libra, the sign of balance, and to Venus — the planet of attraction. The hint “the seventh is about the couple” works, but it doesn't turn partnership into harmony: for a person with Aries on the Descendant a couple is built through argument and rivalry, and that is read from Aries.
How to read the 7th house in your chart
The sign on the Descendant
The sign at the start of the seventh house is always opposite the sign of the Ascendant: Ascendant in Leo — Descendant in Aquarius. It describes which people you attract and what you expect from a partner: fire — initiative, earth — reliability, air — conversation and freedom, water — closeness and feeling.
The manner of each sign at the start of a house — on the pages of the zodiac signs.
Planets in the 7th house
Planets in the seventh house — what comes through partners: Saturn — a union with an older or very serious person, relationships as an obligation; Jupiter — generous and useful partners; Mars — arguments and rivalry in the couple; Uranus — sudden beginnings and breakups, a need for freedom; Venus — ease and attraction.
What each planet means and how to read it by house: Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.
The ruler of the 7th house
The ruler of the seventh house shows where you meet partners and what binds you: in the tenth — through work, often a colleague or a boss; in the ninth — a person from another country or culture; in the third — a neighbor, a fellow student, someone from the close circle.
If the 7th house is empty
An empty seventh house is found in about half of people, by our measurement even slightly more often than the other houses — and it isn't “there will be no marriage.” The couple is then read from the sign on the Descendant, its ruler and Venus.
The rulers of all twelve signs are in the table on the page of all houses.
How to check it on yourself
Each statement below may turn out to be false about you — that’s how it’s written. Check it against your past, and write your answer down before you compare it with the chart. The first item checks the calculation itself, the rest — the interpretation.
If your Sun is in the 7th house
What should match. Your birth time falls in the last third of the interval from true noon to sunset — shortly before sunset. Sunrise and sunset for the day and city of your birth are in any astronomical calendar; true noon is exactly halfway between them, true midnight is twelve hours after noon.
When it’s not about you. The time on your birth record doesn’t fall in this window and is more than a quarter of an hour from its edge — then the wrong time, time zone or city went into the calculation, and the houses in the chart aren’t yours. This checks the calculation, not the interpretation.
If Saturn is in the seventh house
What should match. Write down your three longest unions — marriage, a relationship, a business partnership. At least one of them is with a person noticeably older than you, by five years or more, or very serious, “adult” in character, and it felt like an obligation, not like ease.
When it’s not about you. None of the three fits, either by age or by description — a contradiction.
If Uranus is in the seventh house
What should match. At least one union that lasted more than a year began within a matter of days or ended abruptly, without a long fading.
When it’s not about you. All long unions began gradually and ended slowly — a miss.
If the ruler of the seventh house is in the tenth
What should match. You met at least one of your main partners through work.
When it’s not about you. No main partner is connected with work — a miss. Meeting at work is common, so a hit proves little, and a miss is an honest negative result.
