Planet positions use a deterministic astronomy engine. Unknown birth times use noon and make the Rising sign an estimate.

Frequently asked questions

How is this birth chart calculated?

Planet positions are calculated by an astronomy engine from your date, time and coordinates. AI is not used for astronomical calculations.

What if I do not know my exact birth time?

You can still calculate planetary signs, but the Rising sign and houses are less reliable without an exact time.

Is my birth data private?

Guest calculations stay in your browser. Signed-in users can choose to sync readings to their private account.
