If the planets are the actors in a birth chart and the signs describe how they act, the houses are the stage: the areas of life where everything happens. There are twelve of them, and between them they cover a whole life, from the body you arrive in to the parts of yourself you keep out of sight.

The houses are drawn from the horizon at the exact time and place of your birth. That is why they are the most personal part of a chart. Two people born on the same day in the same city share almost every planet, but if they were born a few hours apart, their houses can be completely different.

The cusp and its sign

Each house begins at a point called its cusp, and every cusp falls in a sign of the zodiac. That sign colours the whole house. It describes the attitude you bring to that area of life, the style in which you handle it, whether or not any planet lives there.

This matters because most charts have several empty houses. An empty house is not an empty area of life. Someone with no planets in the seventh house still has relationships; the sign on the seventh cusp says what they look for in a partner and how they behave in one. With Cancer there, a partnership is meant to feel like home. With Aquarius there, it is meant to leave plenty of room to breathe, ideally with separate opinions and possibly separate desks.

The sign on a cusp also points to a planet: the one that rules that sign. If Leo is on your tenth house, the Sun has a say in your career wherever it sits in your chart. Following these threads is how astrologers connect one area of life to another.

The twelve houses

The first house begins at the Ascendant, the sign rising in the east when you were born. It is the self as others first meet it: your manner, your appearance, the way you walk into a room. Its sign is your rising sign, and it is the one house our report always gives the highest importance.

The second house is what you own and what you value: money, possessions, and the sense of worth that sits underneath them.

The third house is your immediate world: communication, everyday learning, siblings, neighbours and short trips. It is where you talk, write and listen.

The fourth house is home, family and roots: where you come from, and what you need to feel settled. Its cusp is the lowest point of the chart.

The fifth house is pleasure and creativity: romance, play, children, hobbies, anything you do because you enjoy it.

The sixth house is daily life and work: routines, duties, colleagues, and the habits that keep everything running.

The seventh house begins at the Descendant, opposite the Ascendant. It is partnership in every form: love, marriage, close collaborators and open rivals. It describes what we seek in another person, often the qualities we have not yet developed in ourselves.

The eighth house is what is shared and what is hidden: intimacy, other people's resources, inheritance, crisis and deep change.

The ninth house is the wider world: long journeys, higher education, beliefs, philosophy and the search for meaning.

The tenth house begins at the Midheaven, the highest point of the chart. It is career, reputation and public life: what you want to be known for.

The eleventh house is friends, groups and communities, and the hopes you share with them.

The twelfth house is the most private room in the chart: solitude, the unconscious, what we keep behind the scenes, and the quiet strength we find when we stop performing.

How the sign changes the house

The same house reads very differently depending on its sign. Picture three people with three different signs on the second house, the house of money. With Taurus there, money is about security, comfort and patience, and saving is a pleasure rather than a sacrifice. With Sagittarius there, money is fuel for experience, and a budget is more of a hopeful suggestion. With Virgo there, money is a system, and this person probably knows exactly how much the last coffee cost.

Or take the tenth house, career. Capricorn on the Midheaven tends to want a long climb towards real authority. Pisces there tends to want work that means something, and may take a winding road to find it. Neither is better. They are different answers to the same question.

What our report shows

The houses in signs are the last section of our "Aspects, Combos, Houses" report. You get twelve readings, one for each house, written for the sign on its cusp, with the exact degree of the cusp beside it. The first house is always given five stars of importance, since it describes your Ascendant. The other houses are rated by how much weight they carry in your particular chart, so the areas of life where your chart is busiest rise to the top in importance.

Above the readings, you can ask the AI astrologer to synthesise all twelve into a single picture of how your life is laid out.

The houses are calculated with the house system set in your profile, Placidus by default. In Placidus and similar systems the houses are not all the same size, so in some charts a sign appears on two cusps in a row while another sign does not begin any house at all. That is normal, and it simply means one sign colours more of your life than another.

The birth time matters most here

The houses depend on the Ascendant, and the Ascendant moves about one degree every four minutes. An error of an hour can shift every cusp by a whole sign. That is why this section needs a reliable birth time. Without one, it is better to leave the houses out than to read them from a guess, and the rest of the report, the aspects between planets, still stands on its own.

When you are ready, read your twelve houses in their signs here, starting from the first house and your rising sign.

Frequently asked questions

What are the houses in a birth chart?
Twelve divisions of the chart, each standing for an area of life, from the self and money to partnership, career and the private inner world. They are drawn from the horizon at your time and place of birth.

What does the sign on a house cusp mean?
It describes your attitude and style in that area of life. It applies whether or not any planet is in the house, and it also points to the planet that rules that sign, which then has a say in that area.

I have empty houses. Is something missing?
No. Most charts have several empty houses. The area of life is still there, and the sign on its cusp describes how you approach it. An empty house is simply not where your chart concentrates its energy.

Why do some signs appear on two houses, and some on none?
In unequal house systems like Placidus, the houses vary in size, especially far from the equator. A large house can contain a whole sign without that sign beginning any house. It is a normal feature of many charts.

Which house system do you use?
Whichever you set in your profile, Placidus by default. The planets and their signs are the same in every system; only the cusps, and so the houses, differ.

Can I read the houses without a birth time?
Not reliably. The cusps move about one degree every four minutes, so an hour of error can change every sign on every house. With an unknown birth time, read the planets and aspects and leave the houses aside.
