What is a birth chart?
A birth chart, or natal chart, is a map of the sky at the exact moment and place you were born. It shows which zodiac sign each planet was in, and how the twelve houses were laid out over your birthplace.
Your sun sign is one line of that map. The full chart shows the rest: your emotional needs (Moon), how you think (Mercury), how you love (Venus), how you act (Mars), and where in life each of those plays out.
How to read your natal chart
Signs are the style: a planet in Aries acts fast, in Taurus it takes its time. Houses are the stage: the 7th house is partnership, the 10th is career and reputation. Planets are the actors: each one is a different part of you.
Read a placement as a sentence: “My Venus (how I love) is in Cancer (protectively) in the 5th house (in romance and play).” Start with your Sun, Moon, and rising sign, then add one planet at a time.
Frequently asked questions
How do I read my birth chart?
Start with your big three: the Sun (who you are), the Moon (what you need), and the rising sign (how you meet the world). Then look at each planet’s sign for its style and its house for the area of life it works in.
Do I need my exact birth time?
For the full chart, yes. The rising sign and the houses move quickly through the day. Without a time you still get every planet’s sign, and we flag any planet that changed sign on your birthday.
Which house system do you use?
Placidus, the most common system in Western astrology, with the tropical zodiac.
Is the birth chart calculator free?
Yes. The chart wheel, positions, and short readings are free with no email or account. An optional six-chapter natal report, written for your chart, is $19.9 one time.
Is my birth data stored?
The free calculator does not save your birth data. It is stored only if you buy the report, so it can be delivered to you.
