The Akan ADADUANAN — the 42-day ritual cycle of Ghana and Côte d'Ivoire, the calendar behind AKWASIDAE at the Manhyia Palace and the day-naming system that gave the world Kofi (Friday-born) Annan. The cycle is the least common multiple of the seven-day nnawɔtwe (Ɛdwoada Monday … Kwasiada Sunday) and the six-day nnanson (Fo, Nwuna, Nkyi, Kuru, Kwa, Mono), with the four dabɔne (sacred days) at FIXED positions whose weekday identities are theorems the engine proves at load: Fɔdwo day 1 (always a Monday), Awukudae day 10 (a Wednesday), Fofie day 19 (a Friday), Akwasidae day 28 (a Sunday, every 42 days). ANCHORED to a nine-date published Akwasidae chain from two independent sources — 2025-12-21 and the full 2026 calendar (Feb 1 through Nov 22) — every pair exactly 42 days apart, all reproducing as cycle day 28, asserted at load. Any date returns its cycle day, compound day name (constructed per the documented pattern, labeled as such), dabɔne flag, the NEXT Akwasidae, and — for a birthdate — the KRADIN soul name by weekday (Kwadwo/Adwoa Monday … Kwasi/Akosua Sunday; the engine even sides with the biographers on Nkrumah: his official Tuesday birthdate cannot yield the Kwame his name records). The nine-cycle ritual year (378 days, the ninth Akwasidae as Odwira/Adae Kese) is served as the tradition states it — never forced onto the solar year. Community variance named; local practice governs. Pure computation, no LLM.
