Questions people ask
What are the Big Three in astrology?
Your Sun, Moon and Rising signs. The Sun sign describes your core character, the Moon sign your emotional needs, and the Rising sign how you come across to people when they first meet you.
Why does my Rising sign need a birth time and city?
The Rising sign is the sign coming up over the eastern horizon at the moment you were born. It changes about every two hours, so a date alone cannot give it, and the city sets where that horizon was.
What if I do not know my birth time?
You still get your Sun sign, your Moon sign (or the two signs it moved between that day) and your sign in six other traditions. A birth certificate often lists the time.
Is astrology scientific?
No. Astrology is a symbolic tradition, and nothing here predicts events. People use it as a set of prompts for thinking about their character and habits, which is how this calculator presents it.
