In the traditional Hawaiian calendar, the lunar month was determined by the 29.5-day cycles of mahina, the moon, and the passage of days were marked by the phases of the moon. The approximately 30 days of the moon cycle were divided into three 10-day periods known as anahulu. The first 10-day period was called “ho‘onui,” “growing bigger,” beginning on the first crescent The second 10-day period was called “poepoe,” “round” or “full,” as the moon became full and round. The nights of the bright moon – Akua, Hoku, and Mahealani – were referred to as “nā pō mahina kōnane,” kōnane meaning “bright moonlight.” Hawaiians plant and fish in accordance with the phases of the moon.
