Date of birth

It sets your rising sign and houses. Don’t know it? That’s fine: tick the box and we’ll leave those out.

Start typing and pick from the list. It sets the time zone.

How the chart is divided: Placidus, the usual way (change)
House system

Houses split the chart into twelve parts of life, like work or home. If you’re not sure, keep Placidus.

What is a birth chart?

A birth chart is a map of the sky at the moment you were born, seen from where you were born. It shows the Sun, the Moon and the eight planets, each in a sign of the zodiac, and it divides the sky into twelve houses. Your sun sign is one line of it. The rest is what makes two people born in the same week read so differently.

What you need

Your date, time and place of birth. The date gives the planets. The time and place give your rising sign and houses, which turn all the way around the sky in a day. If you don’t know your time, you’ll still get every planet, and we’ll tell you plainly what’s left out. A birth certificate or a parent’s memory is the usual source.

Sun, Moon and rising sign

These three are the usual place to begin. The Sun is the steady middle of you. The Moon is your inner weather, the way you settle and what you need when you’re tired. Your rising sign is the front door, the first thing people meet.

Which house system should I pick?

If you’re not sure, keep Placidus. It’s what most websites show, so your chart will match the others you’ve seen. Whole Sign is older and simpler, and many people find its houses easier to read. Both are one click apart here, so you can compare them.

How we calculate

Positions are tropical and geocentric, seen from the centre of the Earth. We checked our calculations against NASA’s JPL Horizons for the planets and the Swiss Ephemeris for houses and nodes, on 39 test charts from 1879 to 2026. The largest planet error was under 20 arcseconds, far smaller than one degree. We don’t calculate Chiron or other asteroids, so you won’t find them here.

What happens to your details

They go to our calculator to work out the chart, then they’re gone. We don’t store them, and they’re not in our logs. Your chart stays free, with nothing to unlock. If you’d like to come back to it, save the image or keep the link, because we can’t look it up for you.
