Do I need my birth time?

Not for your Sun and Moon. Your Rising sign changes roughly every two hours, so it needs the time. If the Moon changed signs on your birthday, the page shows both possible signs instead of guessing.

How accurate is this birth chart?

Planet positions come from real astronomical calculations for your date, time and the coordinates of your birthplace, using the tropical zodiac and Placidus houses. Interpreting them is a tradition, not a science.

Why do I have to pick a city?

Your Rising sign and the local time zone depend on where you were born. Picking from the list gives the calculation the right coordinates. If your town is not listed, choose the nearest larger city.

Are my birth details saved?

No. The chart is calculated in your browser and your date, time and birthplace are not sent to our servers. You do not need an account or an email.
