**Discovery: Neo-Babylonian Astronomical Diaries — Arithmetic Astronomy in the Sexagesimal Register** **1. Mathematical **BM 32313**, -568; **VAT 4956**, -567) record a strictly empirical, arithmetic astronomy. They do not model celestial mechanics geometrically. Instead, scribes tracked the **Moon's Six Intervals** (na₄-gi₁₁-na₄-gi₁₁): first/last visibility, first/last quarter, and full moon. Planetary phenomena (first/last appearance, stationary points) were logged against the **Normal Stars** (*mul mul-gar-ra*), a fixed reference frame of ~31 stars (e.g., *mulGIR.TAB* / β Virginis, *mulKAK.SI.SÁ* / α Virginis) defining the ecliptic path. The goal was prediction via **Goal-Year Texts** (e.g., **BM 34081**), exploiting periodicities (e.g., Saturn 59 yr, Jupiter 71 yr, Venus 8 yr). **2.
