HVD — CHRONAL-VECTOR DIAGNOSTICS

Chronal-Vector Diagnostics (CVD) is an authorial system developed in the post-Soviet space, belonging to the cluster of numerical analytical practices that emerged predominantly in the 1990s-2010s. The system employs specific "chronal" terminology referencing time (chronos) as a structuring principle, and positions itself as a synthesis of numerology, chronobiology, and systematic personality analysis. The details of authorship and development history have not been fully disclosed publicly.

The basis of calculation is the complete birth data: date, month, year, and time of day. From this data, through mathematical operations — computation, decomposition into components, summation in specific combinations — a "chronal matrix" is constructed: a set of numerical codes distributed across positions, each describing a specific aspect of personality, destiny, or life program. The inclusion of birth time as a separate parameter distinguishes CVD from most numerological systems, which are limited to the date.

The system interprets numbers through the lens of an authorial dictionary of meanings — programs, vectors, and patterns. The characteristic language of CVD appeals to the concepts of "code," "program," and "temporal vector" — terminology that creates a quasi-scientific framework for a system that is esoteric in nature. Such language is typical of the post-Soviet synthetic cluster, where scientific rhetoric and mystical content frequently coexist.

In Errarium, CVD (#52) is classified in the post-Soviet numerological cluster alongside the Pythagorean Square (#46), Formula of the Soul (#41), and Syutsai (#53). Its distinctive feature is the inclusion of birth time as a mandatory parameter, which theoretically brings the system closer to astrological methods requiring precise time (Western astrology #1, Jyotish #18), while maintaining a fundamentally numerological calculation mechanism.
