Natal chart questions
Everything you need before you calculate.
What do I need to calculate my birth chart?+
You need your birth date, your birth time as accurately as possible, and your birth city or coordinates. The time and place determine your Ascendant and house cusps.
Why does birth time matter for a natal chart?+
Your Rising sign (Ascendant) and the house divisions depend on the exact birth time and location. Even a few minutes can shift the Ascendant.
What house system does Horoscope use?+
Horoscope uses the Equal House system, where each of the twelve houses spans 30 degrees starting from the Ascendant.
How accurate is the birth chart calculation?+
Planet positions use the VSOP87 astronomical model and are computed in your browser. Interpretations are general, symbolic and for entertainment only.
Is my birth information private?+
Yes. All calculations run locally in your browser; your birth details are never sent to a server.
