How to read a birth chart
A birth chart is a map of the sky at the moment you were born. The twelve signs form the outer ring. The planets show what is acting, the signs show how, and the houses show in which area of life. Aspects are the angles between planets and describe how those parts of you work together. Read it as a language for reflection, not as a forecast.

Questions and answers
Why do I need my exact birth time?
The Ascendant and the house cusps move quickly, roughly one sign every two hours, so they depend on the exact time and place. Without a time the tool still lists each planet's sign, calculated for midday, but leaves out the houses, the Ascendant and the Midheaven.
Which house system does the chart use?
Houses are calculated with the Placidus system, the one most Western astrologers use. Placidus breaks down close to the poles, so for births above 66 degrees of latitude the chart switches to equal houses, where each house spans exactly thirty degrees from the Ascendant.
Why does my chart differ slightly from another website?
Positions here are accurate to a fraction of a degree, which is enough for signs and houses. If a planet sits within a degree of a sign boundary, professional software may place it in the next sign. The North Node shown is the mean node; some sites use the true node instead.
