Attic Calendar of Athens (雅典曆)

THE ATTIC CALENDAR of classical Athens — the calendar of the first democracy, and of history's most famous calendar TAMPERING. Twelve lunar months from HEKATOMBAION (the first new moon after the summer solstice) to Skirophorion, full and hollow days alternating, a second Poseideon intercalated to chase the sun — and beside the festival year, the boule's PRYTANY YEAR of ten tribal months, so every Athenian decree is DOUBLE-DATED. THE REFUSAL IS THE DESIGN (the Qumran lineage, closing a long-parked deferral): NO Gregorian mapping is minted, because none would be honest — the archons inserted and omitted days AT WILL, the decrees themselves split into dates KATA THEON (by the god's moon) and KATA ARCHONTA (by the official fiction), and Aristophanes staged the moon's own complaint. THE THEOREMS ASSERTED: 6×30 + 6×29 = 354 and the embolismic 384; the prytany arithmetic 4×36 + 6×35 = 354 meeting the festival year; the eleven-day solar drift; and the METONIC IDENTITY (19×12 + 7 = 235) asserted in Meton's own city — with the irony served that Athens never adopted her citizen's cycle. Greek becomes eight systems. Pure compute, no LLM.
