Birth Chart

A horoscope is about your Sun sign. A birth chart is about where every body stood in the minute you were born — and that belongs to you, not to your sign.

You will get a chart without the exact time — the signs are there. The Ascendant and houses, though, need the time to the minute.

Common questions

What is the difference between a horoscope and a birth chart?

A horoscope starts from the Sun sign — one data point among many. A birth chart shows all thirteen points, together with the houses and the aspects between them. That is why two people with the same Sun sign can have charts that barely resemble each other.

What if I do not know my exact birth time?

You still get a chart: the signs come from the date alone. What is missing is the Ascendant and the houses, which depend on the Earth turning and so need the time to the minute. The Moon sign can also be uncertain, since it moves about thirteen degrees a day.

Which house system do you use?

Placidus, the most widely used one — most likely what you have seen elsewhere. Beyond the polar circles Placidus breaks down mathematically, so there we switch automatically to Whole Sign houses, and the chart says so.
