Free astrology calculators
Three calculators, one engine: your birth data goes in, a real chart comes out — computed with a NASA JPL ephemeris, not a date lookup table. Every result is free, with no account and no sun-sign guesswork.
Birth Chart Calculator
Your full natal chart: Sun, Moon and rising signs, all ten planet placements, houses and element balance — each placement explained in plain language.
Moon Sign Calculator
Your emotional nature: the sign the Moon was in when you were born, your exact Moon degree, and an honest note if you were born near a sign change.
Rising Sign Calculator
Your Ascendant: how you come across and meet the world. It changes about every two hours, so we calculate it from your exact birth time and place — and never guess.
The Big Three
Sun, Moon and rising — why all three matter
Most horoscopes only use your Sun sign — one placement out of a whole chart. The quickest honest sketch of a person needs three: the Sun (who you are at the core), the Moon (what you need emotionally) and the rising sign (how you come across). These calculators give you all three, calculated, not guessed.

From your chart to your compatibility
A single chart is half a story. Enter a partner's birth details and we calculate both charts, compare every cross-aspect, and give you a free Harmony Index with five dimension scores.
Computed with our own engine on NASA JPL DE421 ephemeris data. Results are for reflection and entertainment.
