Senior Project


Aloha kākou, ʻO au ʻo Kaleo’okalani Hayes. My senior project involved finding a way to make historical and valuable knowledge available in a modern way. Our kupuna had great knowledge regarding the phases of the moon, how the calendar was structured and how these affected daily life. This knowledge is still relevant today.

Hawaiians planted, harvested, celebrated, and rested according to the phases of the moon (the calendar). In order to make the names of the phases and the cycles easier to learn and remember, I developed a mobile application that can be with learners at any time. The convenience of an app makes it easy to use, and allows relatively quick updating (adding new information) as this is a “living” project, which I will continue to develop.

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.

From the webpage of Hawaiian Voyaging Traditions (Hokulea), an excellent source of additional inofrmation on this topic.
