The video debunks the common belief that equinoxes result in equal day and night lengths. It explains that equinoxes are specific moments of astronomical alignment when the Earth's axis is perpendicular to the Sun. Due to the Sun's size and atmospheric refraction, days are slightly longer than nights. The video also highlights how these effects vary with latitude, making equinox day lengths differ across locations.

How does the angle of the sun's approach to the horizon change with latitude?
