What is Vertex in astrology?

Vertex is an angle-related point often read as an encounter or timing marker. It can describe experiences that feel unusually significant, but it does not replace the full chart.

Do I need an exact birth time for Vertex?

Yes. Vertex is calculated from house geometry, so exact birth time and birth location are important. Unknown-time results should be treated as estimates.

Why Regu treats Vertex carefully

Vertex pages often become vague fate language. Regu keeps the technical placement visible and frames the interpretation as timing and encounter context rather than certainty.
