The longest night of the year occurs during which event?

Explanation:
Day length changes because Earth’s axis is tilted, so the Sun’s path across the sky shifts throughout the year. A solstice is the moment when the Sun reaches its most extreme position north or south of the celestial equator. The winter solstice is when the Sun is at its lowest midday height, giving the fewest daylight hours and thus the longest night. Equinoxes are when day and night are about equal, and the Moon’s phase (new or full) doesn’t affect how long the night lasts—it only changes how bright the night is. So the longest night occurs at the solstice, specifically the winter solstice in the Northern Hemisphere.
