What does this calculator do?

A transit chart calculator determines where the planets are at a selected date and time, then compares those positions with natal placements using defined aspect and orb rules.

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

• Transit planet positions
• Transit-to-natal aspects
• Aspect orbs
• Exact-time information when supported
• Data limitations

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

Unknown natal birth time limits aspects to natal angles, houses and the Moon when boundary uncertainty applies. 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.
