Where do solstices come from?

Solstices originate from the Earth's axial tilt and its orbit around the Sun. As the Earth revolves, the tilt causes different parts of the planet to receive varying amounts of sunlight throughout the year. This results in the two solstices: the summer solstice, when the Sun reaches its highest point in the sky, leading to the longest day of the year, and the winter solstice, when the Sun is at its lowest point, resulting in the shortest day. These events have been observed and celebrated by cultures around the world for centuries.
