Astrology · Planet signs
Your planets,
in their signs
You are more than your star sign. Each planet sits in its own sign and colours a different part of you — how you think (Mercury), want (Mars), drive (Sun). Enter your birth date and see them all at once.
Only your birth date is needed.
How it works
Three steps to your signs
Enter your birth date
Your birth date is enough — planet signs need no time.
Calculate the signs
We use the Swiss Ephemeris engine, arc-second accurate, free.
Read your signs
You see every planet sign and can read each placement in detail.
Planet signs — frequently asked questions
- What's the difference from my star sign?
- Your "star sign" is just your Sun sign. But every planet sits in a sign — your Mercury sign shows your thinking, your Mars sign your drive, and so on.
- Do I need my birth time?
- No. A planet's sign depends only on the date. You only need the time for houses and the ascendant.
- How accurate is the calculation?
- Accurate to the arc-second — we use the Swiss Ephemeris, the same standard professional astrology software runs on.
