Sun, Moon and rising sign calculator
Your Big Three are your Sun, your Moon and your rising sign: who you are, what you need, and how you come across. Enter your birth details and see all three, each in words.
What each of the three is
Your Sun is the sign the Sun stood in on your birthday: what you set out to do, and how you go about it. Your Moon is the sign the Moon stood in: what comforts you, and what you go back to when the day has been long. Your rising sign is the sign coming up over the eastern horizon as you were born: how you come across, the first thing people meet.
The Sun and Moon need only your date. The rising sign needs the minute and the place, because it turns with the Earth. The chart is cast to the minute, with the same astronomy professional astrologers use.
If you do not know your birth time
You still get your Sun and Moon signs, and the planets. The chart leaves out the rising sign and the houses, and says so. A parent, a long-form birth certificate or a hospital record can usually give you the time.
Questions
What are the Big Three in astrology?
Your Sun sign, your Moon sign and your rising sign. Together they are the quickest true picture of a chart: who you are, what you need, and how you come across.
Which of the three matters most?
They describe different parts of you, so none replaces the others. The Sun is the best known, the Moon is the most private, and the rising sign is the most visible.
Do I need my birth time for all three?
Only for the rising sign. Your date gives your Sun sign and nearly always your Moon sign.
What comes after the Big Three?
The rest of the planets, each in a sign and a house, and the angles between them. Your free chart shows them all, and the full analysis reads every one.
