९×९ · २८ नक्षत्र · १२ राशि · ८ दिशा
सर्वतोभद्र-चक्रम् Sarvatobhadra Cakra
The all-around-auspiciousness wheel — an 81-cell matrix placing 28 nakṣatras, 12 rāśis, and 8 directions around a fixed centre. Cells on the same row, column, or diagonal as a focus cell are structurally pierced (vedha) — the geometry used in muhūrta and praśna work. PRAŚNA MĀRGA CH. 17 · BPHS CH. 81 · PHALADĪPIKĀ 26.6-26.18

Structure only — the lattice and its piercing lines are geometry; no outcome is predicted here.

गणना · Compute
URL-driven overlayAppend ?nakshatra=N (N = 0..26) or ?moonLon=DEG to overlay vedha analysis. Example: /sarvatobhadra?nakshatra=3 (Rohiṇī).
The overlay takes an index or a longitude — never birth data in a URL.
