Actually, a solstice and an equinox are sort of opposites. The seasons on Earth change because the planet is slightly tilted on its axis as it travels around the Sun. ... The two solstices happen in June (20 or 21) and December (21 or 22).
Why do we have solstices?
Solstices occur because Earth's axis of rotation is tilted about 23.4 degrees relative to Earth's orbit around the sun. This tilt drives our planet's seasons, as the Northern and Southern Hemispheres get unequal amounts of sunlight over the course of a year.
Why do we have equinoxes?
The equinoxes and solstices are caused by Earth's tilt on its axis and ceaseless motion in orbit. You can think of an equinox as happening on the imaginary dome of our sky, or as an event that happens in Earth's orbit around the sun.
