Void of Course Moon (VOC) - Methods, Meaning, and Calculation

Void of Course Moon (VOC) means the Moon will not perfect a major aspect before it changes sign. Different traditions define the boundary differently, so the answer depends on the method you choose.

VOC in this app

Void of Course is handled as an operational timing state. Because traditions differ, the app provides multiple validated profiles and keeps them coherent with the selected zodiac mode and planet set.

To reduce copycat replication, detailed method internals are not fully published in this public article.

Practical use

  • ✦Pick one VOC profile and keep it consistent during comparison.
  • ✦Evaluate VOC together with Moon aspects and ruler condition.
  • ✦Use Advanced panels for context, not as a single yes/no switch.
