The video tutorial explains the concept of the Equinox, which occurs when the Earth's axis is neither tilted towards nor away from the Sun, resulting in equal day and night lengths. It discusses how Earth's tilt and orbit around the Sun cause seasonal changes and variations in daylight length. The video also covers the summer and winter solstices, when the Earth's axis is tilted closest and farthest from the Sun, respectively. The autumn and spring equinoxes mark the transition between these solstices. The tutorial concludes with a reflective question about day length changes after the autumnal equinox.
