Is the turning of the New Year a meaningful event?
time is what keeps everything from happening all at once.
A year is the orbital period of earth.
Due to the Earth's axial tilt, the course of a year sees the passing of the seasons marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility.
the exact date is arbitrary but marks a cycle.
