Free Chart Calculator

One birth chart,
three systems.

Enter your birth details once — get a free reading across Western astrology (planets, houses, aspects), BaZi (Chinese Four Pillars), and Matrix of Destiny, side by side.

BaZi's luck-cycle calculation is gender-specific — this is a property of the traditional method itself, not a comment on identity.

Start typing and pick your city from the list — we'll work out the correct time zone and exact chart automatically.
