Free birth chart

1. The date you were born.

2. The time, as exact as you can find it. The Rising sign and the houses depend on it. If you do not know it, tick the box: you still get the Sun, the Moon and every planet.

3. The place. Nadir knows some 70,000 towns and cities, each with its historical time zone.

What you get

The wheel of your chart, drawn in front of you. Sun, Moon and Rising, each with a short reading and a question to write about. A table with the sign, degree and house of every planet, and the closest aspects between them.

Positions come from astronomy-engine, an open astronomy library, in the tropical zodiac and as seen from the Earth. Houses are Placidus; close to the poles, where Placidus is undefined, whole sign. The lunar node is the mean node. The birth time is converted with historical time zone data, so old daylight saving changes are taken into account.

We do not store these details. The chart is drawn and forgotten.

How it is made

Do I need my exact birth time?

No. Without it Nadir leaves out the Rising sign and the houses, which change every few minutes, and shows everything else. If the Moon changed sign on the day you were born, you get both readings.

Is it really free?

Yes. The chart is free and needs no account and no email address.

Do you keep my birth details?

No. They travel to our server, the chart comes back, and your birth details are not stored.

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

A horoscope column speaks to everyone born under one Sun sign. A birth chart is drawn for one minute and one place, with the Moon, the planets and the Rising sign, so no two are quite alike. Nadir reads it as a mirror for reflection, not as a forecast.

Which zodiac and house system does Nadir use?

The tropical zodiac and Placidus houses, the most common choices in Western astrology.
