SEFIRAT HAOMER — the Counting of the Omer: the 49 nights counted aloud from the second day of Pesach (16 Nisan) to the eve of Shavuot, in the same words in every community on earth — 'Today is X days, which are Y weeks and Z days, of the Omer' — with the Kabbalistic layer that made the count a ladder: the 7×7 grid of the seven lower sefirot, each week an outer quality and each day an inner one (day 1 Chesed sheb'Chesed; day 33, LAG BAOMER, Hod sheb'Hod; day 49 Malchut sheb'Malchut). RIDES THE VERIFIED HEBREW ENGINE, and THE STRUCTURAL THEOREMS ARE PROVED AT LOAD ACROSS TWO CENTURIES (5700–5900): because Nisan is always 30 days and Iyar always 29, day 33 IS 18 Iyar and day 49 IS 5 Sivan in EVERY year, with Shavuot the morrow of the count — asserted, not assumed — plus the published civil anchors of 5786 corroborated between two independent services (Hebcal, Chabad): 3 April, 5 May, 21 May 2026. THE CUSTOMS SERVED AS THE DIVERGENCES THEY ARE: the semi-mourning period's three main customs named with their sources (Shulchan Aruch OC 493, the Rema's glosses) and ruled on by nobody; the concordant missed-day practice described, not decreed; NOT A PSAK stated in every payload. Evening-count disclosure on every response (Hebrew days begin at sunset). Kabbalistic becomes seven systems. Pure compute, no LLM.
