Questions people ask
What is a birth chart?
A birth chart is a map of where the Sun, Moon and planets were, from the point of view of your birthplace, at the moment you were born. Astrologers read it as a description of temperament and tendency — not as a forecast.
Do I need my exact birth time?
For your Sun sign and most planets, no. For your Rising sign, your Midheaven and your houses, yes — those change roughly every two hours. If you do not know your time, tick the box and you will still get an accurate reading for everything else.
Where can I find my birth time?
Usually on a long-form birth certificate, in hospital records, or from a parent. Some countries record it as standard, some do not.
Which house system do you use?
Placidus, the most common system in modern Western astrology. Very close to the poles Placidus is mathematically undefined, so the chart falls back to whole-sign houses and says so.
