Houses in astrology are the twelve sections of a birth chart, and each one stands, in astrological tradition, for an area of life: self, resources, communication, home, creativity, work, partnership and so on. If you have looked at your chart and wondered what “6th house” or “10th house” is meant to tell you, this guide walks through all twelve in order. It also explains why the same birth details can put a planet in different houses depending on the system, and how to find your own. Everything here is tradition, offered for reflection and entertainment.
What the houses in astrology are
A birth chart is a map of the sky from one place at one moment. The planets and signs show what was where. The houses divide the same map differently: they cut the sky into twelve sectors using the horizon and the meridian, the line running from north to south through the highest point above you. Popular guides, from the Almanac to Chani, describe the houses as segments of the chart that represent distinct areas of your life, and that is how most astrologers use them.
A common way astrologers teach this is a three-part shortcut: the planet is what, the sign is how, and the house is where. Almanac.com puts the last part as “The houses show where the action is going down.” So Venus in Taurus in the 5th house would be read, in that shorthand, as affection (what), expressed steadily (how), in the area of creativity and play (where).
The planets and signs are astronomy: they can be measured. The houses add a layer of convention on top, which is why the same chart can be read with different house systems, as you will see below.
Why birth time matters
The houses sweep around the sky once a day as the Earth turns, so the house a planet occupies depends on the exact time of birth. Two people born in the same city on the same morning, a few hours apart, share most of their planetary signs and can still have completely different houses, because the Ascendant has moved on.
We computed how long each sign spends rising over the eastern horizon, for one date (21 June 2001). At the equator every sign takes between 1.85 and 2.14 hours. At 51.5 degrees north, roughly the latitude of London, Aries takes 0.88 hours while Virgo takes 2.84. So the window in which your first house begins in a given sign can be under an hour or nearly three, depending on the sign and on where you were born. If you do not know your birth time, a chart can still show your planets in their signs, but it cannot show houses at all. Our methodology page explains what we leave out in that case and why.
Where the first house begins
The first house starts at the Ascendant, the degree of the zodiac rising over the eastern horizon. Sepharial (1910) defines it in these words: “the Ascendant (the degree which is rising)”. From there the houses run counter-clockwise below the horizon and then up over the top of the chart, so the first house is at the left of the wheel, the fourth at the bottom, the seventh at the right and the tenth at the top.
Two house systems, two answers
The horizon and the meridian give the chart its frame, but there are several ways to cut the twelve slices, and each gives a slightly different result. Wikipedia’s summary of the subject puts it plainly: “It is impossible for any system to satisfy all the criteria completely, so each one represents a different compromise.” This is one of the places where astrologers themselves disagree, so we always say which system we use.
Placidus and Whole Sign in plain words
Placidus is, in Wikipedia’s words, “the most commonly used house system in modern Western astrology”. Its houses have unequal sizes, as the example below shows. It belongs to the quadrant family of systems, which put the Ascendant on the edge of the first house and the Midheaven on the edge of the tenth. Our birth chart calculator uses Placidus by default.
Whole Sign is the simplest system. The sign that holds the Ascendant becomes the whole first house, the next sign is the second house, and so on, so every house is exactly 30 degrees and lines up with a sign. In this system the Midheaven is not the start of the tenth house. Wikipedia notes that it can land “anywhere in the 7th, 8th, 9th, 10th, 11th, 12th, depending on the latitude”. You can switch the calculator to Whole Sign and compare.
Where they disagree
To see how much the choice matters we built an example chart for an invented person born on 15 June 1990 at 2:30 pm in Chicago. The Ascendant is 14 degrees 39 minutes of Libra. Under Placidus the house edges fall at unequal distances: the first six houses measure, in order, roughly 27, 31, 34, 34, 29 and 24 degrees (the seventh to twelfth mirror them). Under Whole Sign each house measures 30.
We counted 11 placements: the ten planets and the Moon’s North Node. Seven of the eleven land in a different house depending on the system:
| Placement | Placidus | Whole Sign |
|---|---|---|
| Moon | 5th | 6th |
| Mercury | 8th | 9th |
| Mars | 6th | 7th |
| Jupiter | 9th | 10th |
| Uranus | 3rd | 4th |
| Neptune | 3rd | 4th |
| North Node | 4th | 5th |
The Moon is a good illustration of how a small gap decides it. It sits at 19 degrees 33 minutes of Pisces, and the Placidus sixth house begins at 20 degrees 13 minutes of Pisces, forty minutes of arc further on. So the Moon is in the fifth house under Placidus and in the sixth under Whole Sign, which begins at the start of Pisces. The other four placements, including the Sun in the ninth house, stay put in either system. Astrologers who prefer one system will say the other misplaces planets, and they are describing a real difference in method, not a mistake in the arithmetic.
Near the poles
Placidus has a geometric limit. Wikipedia notes that it “is sometimes not defined beyond polar circles (latitudes greater than 66°N or 66°S)”. If you were born that far north or south, we switch to Porphyry houses and say so on the result.
Angular, succedent and cadent houses
Astrologers sort the twelve houses into three groups, which Wikipedia phrases as “Angular, Succedent and Cadent”. The groups repeat around the wheel in that order:
- Angular houses (1, 4, 7, 10) begin at the four angles of the chart. In quadrant systems these are the Ascendant on the first edge, the Midheaven on the tenth, and the two points opposite them.
- Succedent houses (2, 5, 8, 11) follow each angular house.
- Cadent houses (3, 6, 9, 12) come last in each group and lead into the next angle.
This answers a question people often search: the 1st, 4th, 7th and 10th houses are the angular houses.
The grouping matters in a reading because of emphasis. Traditionally, astrologers treat planets in the angular houses as the most prominent in a chart, and those in the cadent houses as the quietest. Skyscript’s guide to traditional astrology says a planet in an angular house “is much more forceful in its effects than it would be in a cadent house”, and modern guides still call the angular houses the most prominent part of a chart. A planet right on one of the four angles, such as the Ascendant or the Midheaven, is read as more prominent still. In the example chart above, Jupiter sits 1.3 degrees before the Midheaven: that is the end of the 9th house under Placidus and the 10th under Whole Sign, but it is on the angle in both, so an astrologer would call it prominent either way. Prominent here means emphasised in the reading. It is not a verdict on a house, and no house is better or worse than another.
The 12 houses in astrology
Here is the whole set at a glance. The keywords are our own summary of modern usage. The sign in the last column is the one each house echoes: Alan Leo (1903) tells readers of a chart to “pay special attention to the corresponding house” for a sign, the same pairing astrologers use today: house 1 with Aries, house 2 with Taurus and so on.
| House | Name | Keywords | Echoes | Group |
|---|---|---|---|---|
| 1 | Self | identity, appearance, approach, beginnings | Aries | Angular |
| 2 | Resources | values, possessions, self-worth, security | Taurus | Succedent |
| 3 | Communication | communication, learning, siblings, neighborhood | Gemini | Cadent |
| 4 | Home and Roots | home, family, roots, foundations | Cancer | Angular |
| 5 | Creativity | creativity, play, romance, self-expression | Leo | Succedent |
| 6 | Work and Routine | routine, service, daily work, habits | Virgo | Cadent |
| 7 | Partnership | partnership, commitment, cooperation, others | Libra | Angular |
| 8 | Shared Resources | intimacy, trust, shared resources, change | Scorpio | Succedent |
| 9 | Meaning | belief, travel, higher learning, perspective | Sagittarius | Cadent |
| 10 | Vocation | vocation, reputation, public life, achievement | Capricorn | Angular |
| 11 | Community | friendship, community, networks, hopes | Aquarius | Succedent |
| 12 | Solitude | solitude, reflection, the unseen, retreat | Pisces | Cadent |
Each entry below quotes Sepharial, whose 1910 book Astrology: How to Make and Read Your Own Horoscope is one of the plain-language early texts. He lists the matters each house governs. We quote a short clause at most and leave out the parts that read as predictions, and we then describe what modern astrologers add.
1st house: self
Sepharial (1910) begins with “personal appearance”. The first house is the house of how you come across: your manner, your presence, the way you begin things. Modern astrologers read it as self-image and approach, which is why the rising sign, the sign on the first house edge, is so often described as a first impression.
Planets in this house are said to be very visible in a person’s style. An empty first house is not a gap, since the sign on its edge and the planet that rules that sign still describe the house. It echoes Aries, the sign of the first step. The longer page is the 1st house.
2nd house: resources
For the second house Sepharial (1910) lists “finance, movable effects, commerce”. Modern usage keeps the material side and adds what you value: possessions, earnings, talents and a sense of self-worth. Astrologers describe it as the house of what feels truly yours and what you are willing to work for.
Read as a description and never as advice, a planet here is said to colour your relationship with comfort and ownership. The house echoes Taurus, the sign associated with steadiness and the senses. More on the 2nd house.
3rd house: communication
Sepharial (1910) says the third house governs “short journeys, letters, and other means of communication”. The reading has aged well, because everyday messages and short trips are still what most of us do daily. Modern astrologers add learning, curiosity, siblings and the neighborhood around you.
This is the house of the immediate environment, the people and information you meet every day. It echoes Gemini, the sign linked with talk, questions and quick exchange, and it is a cadent house that leads toward the fourth. See the 3rd house for the detail.
4th house: home and roots
Sepharial (1910) links the fourth house with “the residence” among other matters. It sits at the base of the chart, and astrologers read it as your private foundations: home, family, ancestry and the place you come from. This is the part of life that is not on display.
The fourth house edge sits directly opposite the Midheaven at the top of the chart. The house echoes Cancer, the sign of the home and of belonging, and it is the first angular house below the horizon. The 4th house has a page of its own.
5th house: creativity
Sepharial (1910) mentions “social pleasures” alongside other matters. Modern astrologers keep the pleasure and add creative work, play, hobbies and romance: the things you make or enjoy for their own sake rather than for their use. It is often called the house of self-expression.
Planets here are said to show how a person has fun and how comfortable they are being seen doing what they love. It echoes Leo, the sign of performance and warmth, and it is the first house of the second group. Read on in the 5th house.
6th house: work and routine
Sepharial (1910) lists “servants, and personal comforts” among the sixth house’s concerns. Today astrologers use it for the rhythm of ordinary days: daily work, routines, duties, colleagues and the habits that keep a life running. It is the house of practical skill built by repetition.
We treat it as a house of craft and routine only. Older texts attach health language to it, and we do not, because a birth chart is not a place to look for health guidance. The house echoes Virgo, the sign of care for detail. The full page is the 6th house.
7th house: partnership
For the seventh house Sepharial (1910) lists “contracts, agreements, partners”. It begins at the Descendant, the point opposite the Ascendant, and astrologers read it as the house of the other: close partnerships, commitments and the people you meet one to one, whether personal or professional.
If the first house is how you meet the world, the seventh is how you meet one other person within it. The house echoes Libra, the sign of balance and cooperation, and it is the third angular house. The 7th house goes further.
8th house: shared resources
Sepharial (1910) includes “legacies and dowries” in the eighth house, the language of shared and inherited property. Modern astrologers extend it to shared money, trust and intimacy, and describe it as the house of the deeper changes life brings: endings, renewals and what is held in common.
Because the house can sound heavy, it helps to hold it as a description of depth and of joint resources rather than as a forecast of anything. It echoes Scorpio, the sign traditionally linked with intensity, and it is a succedent house. More in the 8th house.
9th house: meaning
Sepharial (1910) lists “long journeys, publications, religious beliefs, foreign lands” among the ninth house’s matters. Astrologers today describe the ninth house as the house of the wider view: travel, higher learning, belief and the search for perspective.
The third house deals with the near and the everyday, and the ninth with the far and the abstract, so the two are often read as a pair. It echoes Sagittarius, the sign of the traveller and the seeker, and it is a cadent house. See the 9th house.
10th house: vocation
Sepharial (1910) sets the tenth house over “position, honour and fame”. Astrologers read it as your public direction: vocation, reputation and the work you become known for. The house and the Midheaven are not always the same thing: in Whole Sign the Midheaven can fall in another house, as we saw above.
In quadrant systems the tenth house begins at the Midheaven, the highest point of the chart, and popular guides associate that point with career and public image. It echoes Capricorn, the sign of structure and ambition. The longer read is the 10th house.
11th house: community
Sepharial (1910) describes the eleventh house as governing “friends, social relations, societies and companies”. Modern astrologers add networks, groups, causes and the hopes you share with others, so the house is often summed up as community.
If the seventh house is about one person, the eleventh is about many. It echoes Aquarius, the sign linked with friendship and shared ideals, and it is the last succedent house of the wheel. The 11th house covers it at length.
12th house: solitude
Sepharial (1910) associates the twelfth house with “all limitations of the personal freedom”, a stern reading typical of the period. Later astrologers reworked the house into a gentler picture: solitude, reflection, retreat and whatever happens behind the scenes, away from ordinary awareness.
You can think of it as the house of the unseen. A planet here is often described as working quietly. It echoes Pisces, the sign of imagination and dissolving edges, and it is the last cadent house, leading back round to the first. The detail is in the 12th house.
How to find your houses
You need three things: your birth date, your birth place and, above all, your birth time. Our birth chart calculator takes all three, works out the Ascendant and the house edges, and lists which house each planet falls in. It uses Placidus by default and lets you switch to Whole Sign.
If your birth certificate does not state the time, ask the hospital or a relative, since even a rough time is better than none. Without one the tool shows your planets in their signs and leaves out the houses, because a wrong time would give wrong houses.
Once you have your houses, how to read a birth chart shows the order in which to look at everything else, and the guide to the Sun, Moon and rising signs covers the three placements that come before the houses.
Empty houses and crowded houses
Every chart has all twelve houses, and it is normal for some to hold no planets. In the example chart above, five of the twelve houses are empty of planets under either system. Under Placidus they are the 1st, 7th, 10th, 11th and 12th. Under Whole Sign they are the 1st, 3rd, 5th, 11th and 12th.
An empty house does not mean that area of life is missing. Astrologers read it through the sign on its edge and through the planet that traditionally rules that sign, wherever that planet sits. A house with several planets, sometimes called a stellium, is read as an area given extra emphasis. Both cases are descriptions for reflection, and neither is a forecast.
Reading a house in three steps
A simple routine works for any house. First, note the sign on its edge. Second, note any planets inside it. Third, find where the ruler of the edge sign sits, and read the two houses together. Practice it on one house at a time, starting with the one you are most curious about, rather than trying to read all twelve at once.
The houses are a tradition, not a measurement
The houses are one of astrology’s most useful tools and also one of its most debated. Astronomy gives us the horizon and the meridian, and the rest is convention: which system to use, how to divide the sky, what each sector stands for. Wikipedia’s astrology entry states that scientific studies have found the practice to have “no scientific validity or explanatory power”. We share that here because we would rather you use the houses as a vocabulary for reflection than as a source of answers.
Questions people ask
Enter your birth date, exact birth time and birth place into a birth chart calculator. It works out the Ascendant and the boundaries of the twelve houses, then lists the house each planet sits in. Without a birth time the houses cannot be calculated, because they turn once around the chart in about a day.
They are twelve sections of a birth chart, each traditionally tied to an area of life: self, resources, communication, home, creativity, routine, partnership, shared resources, belief, vocation, community and solitude. Each house is also linked to the zodiac sign of the same number, from Aries for the first to Pisces for the twelfth.
They are the angular houses. Astrologers sort the twelve houses into angular (1, 4, 7, 10), succedent (2, 5, 8, 11) and cadent (3, 6, 9, 12). In quadrant systems such as Placidus they begin at the Ascendant, the Midheaven and the two points opposite them, and planets in them are traditionally read as the most prominent in a chart.
Yes. Every birth chart is divided into twelve houses, whatever the birth details. What differs is which houses hold planets and which are empty. An empty house is normal: it still has a sign on its edge, and astrologers read it through the sign and the planet that rules that sign.
Traditionally, yes. Each house is linked to the sign on its edge, and that sign has a ruling planet: Sepharial (1910) gives Mars as the ruler of Aries and Scorpio, for example. Astrologers read the house through where its ruling planet sits. Modern astrologers also assign Pluto to Scorpio.
There is no single correct answer. Placidus is the most common choice in modern Western astrology, and Whole Sign is the simplest to read because each sign is one house. If you are curious, look at your chart in both: planets far from a house edge stay in the same house under either system.
