Read the sky you were born under

Yes — every calculator, chart wheel and interpretation is completely free, with no sign-up and no email required. There's no paywall and no trial.

Very. We compute planetary positions from the Moshier ephemeris (the same astronomical lineage as the Swiss Ephemeris used by professional astrologers) and resolve historical timezones — including daylight saving — from your birth city, so results match paid astrology software.

Completely. All calculations run inside your browser — your birth date, time and place are never sent to a server or stored anywhere. The only network request is an anonymous city lookup to find your birth coordinates.

Your date of birth, your time of birth and your birth city. Your date and city alone give an accurate Sun, Moon and planets; an exact birth time adds your Rising sign, Midheaven and house placements.

You can still get a meaningful chart — tick 'I don't know my birth time' and we use noon. Your Sun, Moon and most planets will be correct; only your Rising sign and houses need an exact time.

Your sun sign is your core identity, your moon sign is your emotional inner world, and your rising sign is the impression you make on others. Together they're your 'Big Three' and give a far fuller picture than your star sign alone.

Birth chart, sun/moon/rising and every planet sign, Midheaven, compatibility and synastry, composite charts, the 12 houses, transits like Mercury retrograde and Saturn return, plus numerology life path and the Chinese zodiac — over two dozen free tools.

Yes — every calculator is fully responsive and works on phones, tablets and desktop, with no app to install.
