Hilo Moon — Makahiki Calendar

First Visible Crescent · Honolulu, Hawaiʻi
Anchored to the Setting of Hilo & Rising of Makali'i
Each Makahiki year opens when Makali'i (the Pleiades) rises above the eastern horizon exactly as the sun sets — traditionally around November 17th in Honolulu. The anchor Hilo is the first new crescent that appears after that opening — the lunar cycle that begins the active Makahiki season. Every subsequent Hilo marks the start of a new lunar month within the year, until the cycle closes with the next Makali'i rising. The table groups all Hilo events by Makahiki year rather than Gregorian calendar, restoring the traditional frame of the sky calendar.
Methodology: Makahiki year opens at the acronychal rising of Makali'i (Pleiades, RA 56.85° / Dec +24.12°) — when the cluster first clears the eastern horizon at geometric sunset. Hilo is detected as the first sunset after each new moon when the waxing crescent reaches ≥7.5° altitude above the western horizon. The anchor Hilo is the crescent event with the smallest positive day-offset from the Makali'i opening. All times HST (UTC−10). Location: Honolulu (21.31°N, 157.86°W).
