What does this calculator do?

A birth chart calculator maps the zodiac positions of the Sun, Moon and planets for your birth moment. When an accurate birth time is available, it also calculates the Ascendant, Midheaven, houses and time-sensitive chart points.

This page separates astronomical or arithmetic calculation from interpretation. It reports only values supported by the supplied data and the selected calculation method. Missing information is shown as unavailable rather than replaced with a guessed value.

Results included

• Planet signs and exact degrees
• Ascendant and Midheaven when time is known
• House placements
• Major aspects and orbs
• Retrograde status
• Nodes and selected chart points

How to read the technical result

Check the sign or number first, then review exact degrees, houses, aspects, or reduction steps where they apply. A complete result should identify the input data, calculation system and any limitations. These details make the result reproducible and easier to compare with other professional tools.

Accuracy and data limitations

Without a reliable birth time, planetary signs can still be calculated, but the Ascendant, houses, Midheaven and other time-sensitive positions must be omitted. Names, dates, local times and locations should be entered carefully. A technically correct calculator cannot recover information that was not supplied, and Moodfex does not manufacture missing birth data.
