Big Three Calculator
Your Sun, Moon and Rising sign – free and instant
Your Sun shows who you are at your core, your Moon what you need emotionally and your Rising sign how you meet the world. Together they say far more than your Sun sign alone.
What is the Big Three?
The Big Three are your three key placements: Sun sign, Moon sign and Rising sign (ascendant). They describe your core, your emotional life and how others see you.
Why do you need my birth time?
The Rising sign changes roughly every two hours. Without an exact time it can't be calculated, so we leave it out rather than guess.
Why are two Moon signs shown?
The Moon changes sign every 2–3 days. If it changed on your birthday and the time is unknown, we show both possible signs.
How is it calculated?
With AstroCorex™, our calculation engine built on the open astronomy-engine. Positions are astronomically exact in the tropical zodiac.
