Frequently Asked Questions
Essential information about the free calculators and the use of birth data.
Why is birth time important?
The Rising sign, houses, Midheaven and certain sensitive chart points depend on birth time. Without an accurate birth time, these fields cannot be calculated reliably.
Do the calculators include personal interpretation?
No. The free tools display technical calculation results. Personal astrological interpretation requires evaluating the chart as a whole.
Which astrology system is used?
Western astrology tools use the tropical zodiac and the house system stated on each tool. The calculation method is shown on the result screen.
Can I calculate without knowing my birth time?
Yes. However, only fields that can be calculated reliably without a birth time are shown. The system never assumes 12:00 for an unknown birth time.
Where can I learn what my results mean?
The personal meaning of technical chart data should be evaluated together with other placements and aspects. Moodfex Premium readings are designed for this complete interpretation.
A calculator shows where your placements are. Interpretation explains what they mean within your complete chart.
Personal interpretation of astrological data is the work of experienced astrologers. With Moodfex, you can have your calculated chart data interpreted through comprehensive Premium astrology readings.
