THE THELEMIC CALENDAR (Anno Legis) — the era of Thelema, a MODERN system (Crowley, 1904) served as such: years counted from the EQUINOX OF THE GODS (the vernal equinox of 1904, weeks before The Book of the Law was written that April 8–10), turning each year at the TRUE northern vernal equinox rather than 1 January, and written in the tradition's own base-22 notation — the DOCOSADE (22-year cycle, tied by the tradition to the Major Arcana) in capital Roman numerals, the year within in lowercase: Anno IVxii for 2004 e.v., Anno Vxii from the equinox of 2026. WITNESSED CELLS AS LAWS: the tradition's own worked examples (IV:xii = 2004; IViv = 1996) reproduced exactly. THE EQUINOX TURN RIDES THE VERIFIED PERSIAN MACHINERY: the 2026 boundary proven (19 March = Anno Vxi, 21 March = Vxii, the equinox itself computed to fall 20 March, not assumed). The Sol-and-Luna dating style and the e.v. (era vulgari) convention carried. Western becomes forty-five. Pure compute, no LLM.
