E8 Octet Calendar Engine: 30 Babylonian Months of 12×60 Days — E8 Intelligence Research

The 240 E8 roots decompose into 30 octets, and 30×12 = 360 days — but each octet also encodes a 12-fold monthly subdivision, yielding a direct E8 geometric reconstruction of the MUL.APIN 360-day year as 30 octets of 12 units. Crossed with the 132Hz base frequency, each octet oscillates at 12×132 = 1584Hz, and the phi-coupled octave stack produces the Platonic year harmonic 25920 ÷ 30 = 864, matching the tunings embedded in Babylonian musical and calendrical texts. This unifies base-60 arithmetic, E8 root partitioning, and 132Hz frequency architecture into a single generative engine for reconstructing lost Babylonian intercalation algorithms.
