Scientifically, the year is a complete cycle of seasons. A year is when the earth completes one full orbit of the sun. Its length is measured from one spring quinox to the next spring equinox.
Measuring the time of year was important to most people. Knowing the season was vital when deciding to plant and harvest crops as well as managing livestock in colder climates. Other cultural and religious practices happened at specific times of the year, so it was important to have some sense of time.
Matariki, the Maori New Year, is an important festival that reflects our bi-cultural heritage. This page outlines how a study of Matariki can be used by teachers and students of social studies.
