Based on the moon cycles, the Native American year is divided in to 13 moons with each moon being 28 days long.

Though calendar types vary from tribe to tribe, nearly all tribal calendars begin in the spring; to Native people, spring symbolizes the start of a new year through the birth of new plant and animal life.

Every three years, an additional moon is added to help the Indian calendar coincide with traditional non-Indian calendars.

Some months in the Native American calendar have multiple names for moons. This could be caused by different tribes involved in naming moons, different translations of the same name or the overlapping of more than one moon in the same calendar month.
