Find your Sun, Moon and Rising sign, calculated from the real sky the moment you were born.
What your signs mean
Sun sign
Who you are at your core: your energy, what lights you up, and what you're here to grow into. It only needs your birth date.
Moon sign
How you feel, what comforts you, and what you need to feel safe. The Moon moves fast, so a birth time helps.
Rising sign
The sign on the eastern horizon when you were born: how you come across and how you start things. It needs your birth time.

Good to know
What are the Big Three?
Your Sun, Moon and Rising sign: who you are, how you feel, and how you come across.
Why do I need my birth time?
The Rising sign changes about every two hours, and the Moon changes sign every two to three days, so your birth time makes both exact.
How is it calculated?
From real astronomy: the true positions of the Sun and Moon and the eastern horizon at your birth time and place, using your city's historical time zone, including daylight saving.
Is my birth data saved?
No. The calculator runs in your browser. Nothing you type here is stored or sent to us.
