Nang Songkran (นางสงกรานต์) (宋干女神)

NANG SONGKRAN — Thailand's New Year lady: each year when the sun enters Aries, one of the seven daughters of Kabilaprom descends in procession bearing her father's severed head, and WHICH daughter depends on the WEEKDAY of Maha Songkran day — proclaimed annually by the Bureau of the Royal Household and reported by Thai media the way the West reports a groundhog. GAZETTE-CLASS WHERE IT MUST BE: 2026 PROVED the widely-cited simplified formula can miss the palace's day — its instant sits at ~23:31 on 13 April while the palace's full Suriyayatra procedure lands TUESDAY 14 APRIL 10:34:35 (Raksot Thewi, standing on the pig) — so proclaimed years (2023–2026, verified across the official record) are served from the proclamations, the shortcut is served as the approximation it is, and ITS 2026 ONE-DAY DIVERGENCE IS ITSELF A LOAD LAW. Every proclamation is proven internally consistent (the proclaimed lady must be the proclaimed date's weekday-lady), and the 10:34 instant must yield the proclaimed STANDING posture by the dawn-to-noon rule — a self-check across two independent parts of the proclamation. The seven-lady table (flower, gem, food, weapons, mount) is two-witnessed row for row; unproclaimed years return the shortcut estimate LABELED unofficial with midnight-boundary years flagged. The legend of the riddle-wager and the posture omens served as the tradition they are. Thai becomes three systems. Pure compute, no LLM.
