What is the Hawaiian word for week?

There isn't a single, direct Hawaiian word for "week." The concept of a "week" as a 7-day period is not native to Hawaiian culture.

Instead, they used a lunar calendar based on the phases of the moon. Here are some relevant terms:

* Mahina: This means "month," which was traditionally defined by the lunar cycle (approximately 29.5 days).

* Pōʻalima: This means "Friday," the last day of the traditional Hawaiian work week, which lasted from Monday to Friday.

Therefore, you would need to use a phrase to express "week" in Hawaiian:

* He pule: Literally "a prayer," but used as a common phrase meaning "a week" in modern Hawaiian.

* ʻEhiku lā: Meaning "seven days."

* ʻElua pōʻalima: Meaning "two Fridays," referring to a period of two weeks.

So, depending on the context, you could say "He pule" or "ʻEhiku lā" to express the concept of a week in Hawaiian.
