In respect to this, what seasons do equinoxes occur?

Equinoxes occur when the axis of rotation of the earth (i.e. the line form the N to S poles) is exactly parallel to the direction of motion of the earth around the sun. This happens on just two days of the year, the spring and autumn equinoxes. How often do equinoxes take place on Earth? The equinoxes are the only time when both the Northern and Southern Hemispheres experience roughly equal amounts of daytime and nighttime. On Earth, there are two equinoxes every year: one around March 21 and another around September 22.

Also, what are the 4 equinoxes?

So, in the Northern Hemisphere you have: Vernal equinox(about March 21): day and night of equal length, marking the start of spring. Summer solstice (June 20 or 21): longest day of the year, marking the start of summer. Autumnal equinox(about September 23): day and night of equal length, marking the start of autumn.
