Frequently asked questions
What are the Sun, Moon, and Rising signs?
They’re your "Big Three" — the three most important placements in your chart. Your Sun sign is your core identity, your Moon sign is your emotional inner world, and your Rising sign (Ascendant) is how you come across to others and the lens through which you meet the world.
Do I need my exact birth time to find my Rising sign?
Yes — your Rising sign changes roughly every two hours, so an accurate birth time is essential to calculate it correctly. Your Sun and Moon signs can be found with just your birth date (and, for the Moon, approximate time).
How is this calculator accurate?
It computes real planetary positions from your exact birth moment using a precise astronomical engine — the same calculations professional astrologers use — rather than generic sun-sign tables.
Is it really free?
Yes. Calculating your Big Three is completely free and requires no account. Creating a free Aurae account unlocks your full natal chart — all ten planets, twelve houses, and a personalized AI reading.
