The 12 Astrological Houses

If signs are the how and planets are the what, the twelve houses are the where — the areas of life where the chart's energies actually show up.

What the houses are

The houses divide the chart into twelve life areas, anchored to the horizon at your birth moment. This is why your birth time and place matter: they set the house cusps and your Rising sign. A planet's house tells you which department of life it works in.

House systems

There's more than one way to divide the houses — Placidus, Whole Sign, Koch and others place the cusps differently. AskCelesta lets you switch systems in the chart tool. If you're new, Whole Sign is the simplest to learn; Placidus is the most widely used in modern Western astrology.

Reading a planet in a house

Combine the planet (what), its sign (how), and its house (where). Venus in the 10th house, for instance, brings charm and relationship values into career and public life. Learn the full method in how to read your birth chart.

Frequently asked questions

What are the 12 houses in astrology?

The twelve houses are life areas: self, resources, communication, home, creativity, work and health, partnership, depth, expansion, career, community, and the unconscious.

Why do I need my birth time for the houses?

The houses are anchored to the horizon at your exact birth moment, which moves quickly. Without an accurate time, the house cusps and Rising sign can't be placed reliably.

Which house system should I use?

Placidus is the most common in modern Western astrology; Whole Sign is the easiest for beginners. AskCelesta lets you switch between systems in the chart tool.
