In the traditional Hawaiian calendar, the 29.5-day mahina (moon) cycle is divided into three anahulu (10-day periods): ho‘onui (growing bigger), beginning on the first visible crescent; poepoe (round or full); and emi (decreasing). The traditional names of the Hawaiian moon months and phases may vary by island and moku (district). This calendar uses the O‘ahu moon phases listed in the Hawaiian Almanac by Clarice Taylor. The tides are for Honolulu.
