Seleucid Era (Anno Graecorum) (塞琉古紀元)

THE SELEUCID ERA (Anno Graecorum / מנין שטרות) — THE FIRST CONTINUOUS ERA IN HISTORY: before it, years restarted with every king; from Seleucus I's recovery of Babylon (312/311 BC) this count just KEPT GOING for two thousand years — the conceptual ancestor of every continuous era since, CE included. The era of the Maccabees, the Babylonian astronomical diaries, Syriac church inscriptions from the Xi'an Stele to Kerala, and — as the ERA OF CONTRACTS — of Jewish deeds, kept by Yemenite Jews into living memory. THE TWO RECKONINGS SERVED AS THE DUAL SYSTEM THEY ARE: Macedonian (autumn 312 BC epoch) and Babylonian (1 Nisanu 311 BC) — one year apart every winter, agreeing every summer, exactly the seam the books of Maccabees straddle. ANCHORS AS LAWS: 1 Macc year 137 = Antiochus IV's accession (175 BC, Macedonian); year 145 = the Temple's desecration (25 Kislev 167 BC, Babylonian); year 148 = the first Hanukkah (164 BC); and the Nestorian XI'AN STELE of 781 AD — 'Year of the Greeks 1092' — reproduced exactly (781 + 311). THE HEBREW CROSS-LOCK: SE = AM − 3449, asserted against the catalogue's verified Hebrew engine four years running. Greek becomes seven systems. Pure compute, no LLM.
