Astrology · Houses
Your houses,
calculated
The twelve houses show which life areas your planets work in — from identity (1st) through relationship (7th) to career (10th). Enter your birth data and see your whole house picture at a glance.
Houses need your date, time and birthplace.
How it works
Three steps to your houses
Enter your birth data
Houses depend on time and place — we need your date, time and birthplace.
Calculate the houses
We use the Swiss Ephemeris engine with the Placidus house system — arc-second accurate, free.

You see your whole house framework and can read each placement in detail.
Houses — frequently asked questions
- What are the astrological houses?
- The twelve houses split the chart into twelve life areas — from the self (1st house) to the unconscious (12th). Wherever a planet sits, that is where its force plays out in 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 — the most widely used system in western astrology and the default on astro.com and similar tools.
