Year - Wikipedia

An animation of the inner Solar System planets' orbit around the Sun. The duration of the year is the time taken to go around the Sun. A year is the time taken for astronomical objects to complete one orbit. For example, a year on Earth is the time taken for Earth to revolve around the Sun. Generally, a year is taken to mean a calendar year, but the word is also used for periods loosely associated

"The average duration of the eclipse year is 346.62 days. This term is sometimes erroneously used for the draconic or nodal period of lunar precession, that is the period of a complete revolution of the Moon's ascending node around the ecliptic: 18.6128 Julian years (6798.331019 days)"
