The ancient Armenian calendar (Հայոց տոմար) in BOTH of its historical reckonings, never blended: the MOVEABLE tomar — a 365-day vague year (12 months of 30 days + the five aweleacʿ days, no leap rule) whose New Year, 1 Nawasard, regresses one day against the Julian calendar every four years, completing its full 1,461-year circuit around 2011/12 — and the SARKAWAG calendar, the 1084 reform of Yovhannes Sarkawag (Hovhannes Imastaser) that fixed the year start from AE 533 (11 August 1084) and added a sixth aweleacʿ day every four years. Any Gregorian date returns the Armenian year, the month (transliteration + Armenian script + meaning, Nawasard through Hroticʿ and the epagomenal Aweleacʿ), the day — and the day's NAME, because every one of the 30 days of the Armenian month bears one: the gods, mountains and stars of pre-Christian Armenia (Aramazd, Anahit, Astłik, Mihr, Vahagn; Masis and Aragats), a naming layer the Zoroastrian Roz-o-Mah engine's users will recognize as a sibling tradition. Both reckonings reported side by side where both exist. Ported faithfully from the convertdate reference implementation and locked to its gold vectors; epoch identities (AE 1/1/1 = 11 July 552 Julian) analytic at load; round-trips proven over centuries; all name tables double-sourced with exact-match witnesses. Armenia becomes the catalogue's 30th tradition. Pure computation, no LLM.
