Frequently asked questions about birth charts
How is a birth chart calculated?
The date, time and location of birth are converted into astronomical coordinates, then planets and houses are calculated.
Why does the ascendant depend on birth time?
The ascendant changes quickly during the day, so accurate birth time is essential for a precise result.
Are Moon sign and Sun sign the same?
No. The Sun sign describes core identity, while the Moon sign describes emotional needs and inner responses.
What do house placements mean?
Houses connect planetary placements with life areas such as relationships, career, family and personal growth.
Can I calculate a chart without birth time?
Main planetary positions can still be estimated, but ascendant and houses require an accurate birth time.
