The key detail
You know your star sign, but do you know your houses? They show the areas of life where your planets take action, making your chart so much clearer.
Read along
Two people with the same birthday can have completely different birth charts. The reason is your exact time of birth. It determines the 12 houses in your chart. Think of your chart like a flat. The houses are the different rooms. A planet is a flatmate with a job. The sign is their style. The house is the room they are working in. Is your Venus, the planet of love, in the 10th house of career? You might find great joy in your work. Check for yourself. Find out which areas of life your planets are in.

The 12 astrology houses: how they are calculated
The signs describe how a planet works. The houses describe where in your life it happens. They are calculated from the moment and place of your birth: the point rising over the eastern horizon is your Ascendant and also the cusp of the 1st house. The highest point of the sky is the MC, the cusp of the 10th house. From these axes the sky is divided into twelve sections. Because the Earth turns, every planet passes through all twelve houses once a day, spending about two hours in each. That is why the birth time matters so much.

| House | Life area | Natural sign | Ruler | Type |
|---|---|---|---|---|
| 1st house | Self & Appearance | Aries | Mars | Angular house |
| 2nd house | Money & Values | Taurus | Venus | Succedent house |
| 3rd house | Mind & Communication | Gemini | Mercury | Cadent house |
| 4th house | Home & Roots | Cancer | Moon | Angular house |
| 5th house | Creativity & Romance | Leo | Sun | Succedent house |
| 6th house | Work & Health | Virgo | Mercury | Cadent house |
| 7th house | Partnership & Others | Libra | Venus | Angular house |
| 8th house | Intimacy & Change | Scorpio | Mars / Pluto | Succedent house |
| 9th house | Meaning & Horizons | Sagittarius | Jupiter | Cadent house |
| 10th house | Career & Reputation | Capricorn | Saturn | Angular house |
| 11th house | Community & Hopes | Aquarius | Saturn / Uranus | Succedent house |
| 12th house | Solitude & the Unseen | Pisces | Jupiter / Neptune | Cadent house |

The three house types
- Angular houses (1, 4, 7, 10): start at an angle. Planets here are visible and push outward.
- Succedent houses (2, 5, 8, 11): secure and deepen what the angular houses start. Think of possessions, joy, trust and friendships.
- Cadent houses (3, 6, 9, 12): process experience and turn it into understanding, through conversations, routines, travel and retreat.
The calculator uses the Placidus system, the standard in western astrology. Without a birth time the houses cannot be determined; even 15 minutes can push a house cusp into the next sign. Curious which Rising sign is most common? Read our data study on rising signs. The axis opposite the Ascendant is explained by the Descendant calculator, the 10th-house cusp on the Midheaven page. Every house in depth, with an everyday example, is in our guide to the 12 houses, and how the planets in the houses relate to each other is shown by the aspects calculator.
How often does a chart have intercepted signs?
For births in Germany, Austria and Switzerland, in 77.1 % of all charts. Intercepted means a sign lies entirely inside one house and gets no cusp of its own. It always happens in pairs, because opposite houses are the same size. 71.4 % of charts have one such pair, 5.7 % even two.
It is a question of latitude. The further north, the more the zodiac slants against the horizon and the more unequal the Placidus houses become. In Zurich it is 73.3 %, in Hamburg already 81.7 %, at the equator only 14.5 %. So at our latitude an intercepted sign is the norm, not the exception.

| Place | Share |
|---|---|
| Zurich (47.4° N) | 73.3 % |
| Munich (48.1° N) | 74.4 % |
| Vienna (48.2° N) | 74.6 % |
| Frankfurt (50.1° N) | 77.2 % |
| Cologne (50.9° N) | 78.2 % |
| Berlin (52.5° N) | 80.2 % |
| Hamburg (53.6° N) | 81.7 % |
| Equator | 14.5 % |
| 60° north | 89.2 % |
Computed with the Swiss Ephemeris and Placidus houses, as in our calculator: 248,215 birth moments from 1950 to 2009, spread evenly over every hour and every day of the year, for Zurich, Munich, Vienna, Frankfurt, Cologne, Berlin and Hamburg. Equator and 60° north from the same birth moments. Every hour counts equally, so the numbers show what the sky allows, not when babies actually arrive.
Houses: frequently asked questions
- What are the astrological houses?
- The twelve houses divide the chart into twelve areas of life, from the self (1st house) to the unconscious (12th). The house a planet sits in is where its force shows up in your life.
- Do I need my birth time?
- Yes. Houses are calculated from your time and place of birth (via the Ascendant). Without an accurate time they cannot be determined.
- Which house system do you use?
- Placidus. It is the most widely used system in western astrology and the default on astro.com and similar tools.
