Definition: An "anomalistic year" is a noun that refers to the time it takes for the Earth to complete one full orbit around the Sun, from the point where it is closest to the Sun (called perihelion) back to that same point again. This period is approximately 365 days, 6 hours, 13 minutes, and 53.1 seconds.

Advanced Usage:

In advanced discussions, the anomalistic year can be contrasted with other types of years, such as the "sidereal year" (the time it takes for Earth to complete one orbit around the Sun relative to fixed stars) and the "tropical year" (the time it takes for the Earth to return to the same position in its seasons).
