Vinchudo Dates 2340

Notes: Vinchudo is treated here as the Moon's transit through Vrischika (Scorpio, 210-240 degrees sidereal) — a relabel of the same real Moon Rashi-ingress schedule Transit/Sankranti already use, not a separately-sourced weekday/tithi rule (this site's earlier description of Vinchudo as weekday+tithi based was investigated and found to be an unconfirmed guess, not a cited rule — corrected here). Only one dedicated source was found for this specific mechanism, corroborated by the general (uncontested) fact that Scorpio spans 210-240 degrees sidereal and that the Moon is classically debilitated there — but not independently cross-checked against a second Vinchudo-specific source. Windows are calendar-DATE boundaries at a fixed IST 06:00 reference (same day-level granularity already disclosed for Transit/Sankranti), not exact HH:MM crossing times. Covers 2015-2040 only; a query outside that range returns an empty list, not a fabricated one.
