FAQ
What can I see for free in the Astrowl birth chart calculator?
You can preview your Sun sign, Moon sign, Rising sign, dominant element, and three short personality observations without creating an account.
Do I need an exact birth time?
An exact birth time gives you the most reliable Rising sign and house structure. If you only know an approximate time, Astrowl can still show a useful preview, but the full report is strongest with precise timing.
How is this different from a quiz-based personality test?
Astrowl starts from your birth chart rather than your self-reported answers. The goal is to show personality patterns from chart structure first, then help you explore the details in context.
