Three questions, then your real birth chart is ready
House system: Equal

Placidus divides the houses by angles only a birth time defines, so it cannot be chosen without one. Equal and Whole Sign stay well-defined without a time.

Equal houses: every house is exactly 30°, counted from the Ascendant. The simplest system — the same at every latitude.

The product also has Koch, Porphyry and Regiomontanus. Watching a setting change the result is the fastest way to learn.

A full account defaults to Placidus; pick a different system here and house numbers may look different once you sign up.

What you enter is not stored anywhere and never appears in the address bar.

This page computes 10 bodies; the product computes 22, including Lilith and Chiron.

The arithmetic is free. It stays free.

You do not need an account to compute. You need one to save a chart, compare charts and read an interpretation.
