Sign calculators
Find every sign that makes you you
Your zodiac sign is really several signs working together. Your Sun sign is your core identity, your Moon sign is your emotional world, your Rising sign is how you come across, and Black Moon Lilith is your hidden, instinctive self. Each of the free calculators below finds one of these placements accurately — and the Big Three gives you your Sun, Moon and Rising in a single result.
Common questions
Frequently asked questions
What are the main zodiac sign calculators?
The placements most people want to find are their Sun sign (core identity), Moon sign (emotions), Rising sign or Ascendant (how they come across), the Big Three which combines all three, and Black Moon Lilith (the hidden, instinctive self). Each has its own free calculator here, and each explains what your result means.
Which sign calculators need my birth time?
Your Sun, Moon and Lilith signs come from your birth date alone. Your Rising sign needs your exact birth time and birthplace because it changes roughly every two hours. The Big Three gives your Sun and Moon from your date, and adds your Rising when you provide a birth time and place.
Are these sign calculators accurate?
Yes. Every calculator uses the Meeus astronomical algorithms — the same methods professional astrology software relies on — so your signs are genuinely accurate. They are free, require no sign-up, and run instantly in your browser.
Where should I start?
If you only want the quickest snapshot, start with the Big Three Calculator — it gives your Sun, Moon and Rising in one go. If you want to explore one placement at a time, pick the Sun, Moon, Rising or Lilith calculator individually. For the complete picture, try the full birth chart calculator.
